What Would Cause Low / Slow Water Productions?

To test whether you have High or Low Pressure in the Tank, you will need to follow the below instructions.

Step 1 - Shut off the main water supply and open the RO Faucet to completely drain the water from your tank.
Step 2 - Remove the Blue cap underneath the label on your tank to reveal the Schrader valve.
Step 3 - Check the air pressure using a Digital Air Pressure Gauge (WP161000) for the best results. The results should be between 5 to 7 psi.

Issue 1 - If the pressure is below 5 or at 0 psi, you could have a bad tank. Re-pressurize the tank and check periodically over the next few weeks to verify it is holding pressure.
Issue 2 - If the pressure is above 7 psi, release the excess pressure in the tank so that it is between 5 to 7 psi.

 

Any Crimped Tubing can cause Low / Slow Water Production. make sure that all the tubing is straightened out as much as possible. If necessary replace the tubing.

 

Verify that your Pump Assembly is working properly. Perform the tests here to check your electrical components.

 

Pump Assembly Test

If you have a Missing or Bad Flow Restrictor, you will need to verify it is still in place and has not been removed. Otherwise, you will need to replace it.

Step 1 - Turn off your incoming water and Ball Valve.
Step 2 - Open the RO Faucet to relieve pressure on the system.
Step 3 - Remove the unit from the wall.
Step 4 - Once you no longer hear any water running down the drain, remove the Red Drain Line from the membrane housing and inspect the end of the tube.

Issue 1 - If the flow restrictor is damaged or missing you will need to replace it.

 

Missing Zero Pure Plus Flow Restrictor

A Damaged ASOV (Automatic Shut-Off Valve) can cause Low / Slow Water Production as it will cause the tank to not fill properly. Before beginning the ASOV test, (check the air pressure in your tank) and (verify that your flow restrictor is installed). If both the tank and flow restrictor pass, follow the below steps to test your ASOV.

Option 1 - To Quickly Test the ASOV

Step 1 - Make sure the incoming water to the system is on and turn the tank ball valve off.
Step 2 - Open the RO Faucet and close it when you begin to hear water going down the drain.
Step 3 - Wait 4 to 7 minutes for the draining to stop.

Issue 1 - If the draining stops, there may be an issue with the tank pressure or the filters.
Issue 2 - If the draining does NOT stop after 10 minutes, you will need to replace the ASOV (WP610141).

Items to prepare:

Ꙩ Towel

Ꙩ Measuring Cup

 

Option 2 - Test the Production of the Membrane

Step 1 - Turn off the incoming water supply and the tank ball valve.
Step 2 - Open the RO faucet to relieve System pressure.
Step 3 - *Disconnect the Blue tube from the tank and set it into a liquid measuring cup.
Step 4 - Turn on the incoming water supply; with the tank valve turned off you should see water trickling from the Blue tube.
Step 5 - Collect water for approximately 1 minute and then turn the incoming water supply off.
Step 6 - You should have collected approximately 3 to 6 ounces of water once complete.

Issue 1 - If you are within 3 to 6 ounces then your ASOV is functioning properly.
Issue 2 - If you collect less than 3 ounces, (check the filters and lid).
Issue 3 - If you get more than 8 ounces, you may need to replace the ASOV (WP610141).

Step 7 - Reinstall the Blue tube to the tank.
Step 8 - Turn on the incoming water and tank ball valve. Check for leaks over the next few hours.

Note – Amounts may vary based upon incoming water pressure. Check your system for the next 24 hours to make sure you do not have any leaks.

 

You may have a Clogged Filter or Lid, which can cause Low / Slow Water Production. First, (check to see if the tank is functioning correctly) and (verify that your flow restrictor is installed.) If both the tank and flow restrictor pass their tests, follow the steps below to determine whether the issue is one of the Filters or the Lid Assembly.

Items to prepare:

Ꙩ Towel

Ꙩ Bowl

 

Optional:

Ꙩ Pen or Screwdriver

Step 1 - Make sure the incoming water to the system is on.
Step 2 - Turn the tank ball valve off and open the RO faucet so water will drip.
Step 3 - Remove the Red Sediment Pre-filter (WP105311) and place the bowl underneath the system.
Step 4 - Use your finger or the back of a pen to depress the valve inside the center of the Red filter port on the lid assembly. If water sprays out at a high rate of pressure, reinstall the filter and continue to Step 5. If water does NOT pass through or the water is severely restricted, follow the steps below.

Step a - Turn off the incoming water and depress the valve inside the center of the Red filter port to depressurize the system.
Step b - Remove the unit from the wall.
Step c - *Disconnect the Green tube from behind the Red Sediment Pre-Filter (WP105311).
Step d - Hold the tube over the bowl and slowly turn the water on then off again.

Issue 1 - If water does NOT pass through or the water is severely restricted from the Green tube, then you will need to replace the ASOV (WP610141).
Issue 2 - If water does pass through the Green tube, then you have a clogged lid assembly (WP610051**).

Step 5 - Remove the Yellow Carbon Pre-Filter (WP105351) and depress the valve in the center of the Yellow filter port on the lid assembly. If water sprays out at a high rate of pressure, reinstall the filter and continue to step 6. If water does NOT pass through or the water is severely restricted, follow the steps below.

Step a - Exchange the Red Sediment Pre-Filter (WP105311) with the Silver VOC Post-Filter (WP105381).
Step b - Retest the flow from the Yellow Carbon Pre-Filter port with the Silver VOC Post-Filter (WP105381) installed in place of the Red Sediment Pre-Filter (WP105311).

Issue 1 - If water does NOT pass through or the water is severely restricted from the Yellow filter port, then you have a clogged lid assembly (WP610051**).
Issue 2 - If water sprays out at a high rate of pressure through the Yellow filter port, then the Red Sediment Pre-Filter is clogged. We recommend replacing the Red and Yellow Pre-Filters at the same time (WP531102).

Step 6 - Remove the i Membrane (WP105331) and depress the valve in the center of the Green filter port on the lid assembly. If water sprays out at a high rate of pressure, reinstall the filter and continue to step 7. If water does NOT pass through or the water is severely restricted, follow the steps below.

Step a - Exchange the Yellow Carbon Pre-Filter (WP105351) with the Silver VOC Post-Filter (WP105381).
Step b - Retest the flow from the Green filter port with the Silver VOC Post-Filter (WP105381) installed in place of the Yellow Carbon Pre-Filter (WP105351).

Issue 1 - If water does NOT pass through or the water is severely restricted from the Green filter port, then you have a clogged lid assembly (WP610051**).
Issue 2 - If water sprays out at a high rate of pressure through the Green filter port, then the Yellow Carbon Pre-Filter is clogged. We recommend replacing the Red and Yellow Pre-Filters at the same time (WP531102).

Step 7 - If water sprays our at a high rate of pressure from the Red, Yellow and Green filter ports during testing, perform the (ASOV Test) if you have not done so already.

Step a - If the ASOV test produced less than 3 to 6 ounces of water in 1 minute, exchange the Green Membrane (WP105331) with the Silver VOC Carbon Post-Filter (WP105381).
Step b - With the Silver VOC Carbon Post-Filter (WP105381) installed in place of the Green Membrane (WP105331), depress the valve in the center of the Silver filter port on the lid assembly.

Issue 1 - If water does NOT pass through or the water is severely restricted from the Silver filter port, then you have a clogged lid assembly (WP610051**).
Issue 2 - If water sprays out at a high rate of pressure, then the Green Membrane (WP105331) is bad and will need to be replaced.

*Note - Diagram and instructions for using Quick-Connect Fittings.

Using Quick Connect Fittings

Disconnecting - Ensure the system is depressurized before removing the tube. Push in collet squarely against the face of the fitting. With the collet held in this position, the tube can be removed. The fitting can then be reused.

Connecting - Make certain to push the tubing completely into the connector until it comes into contact with the internal tubing stop. The collet (gripper) has stainless steel teeth which hold the tube firmly in position while the O-ring provides a permanent leak proof seal. Pull on the tube to check that it is secure. It is good practice to test the system prior to leaving the site and/or before use.

**Note - To replace the lid assembly (WP610051) you will need to contact our Tech Support Center at 1-800-752-5582.

***Note - When the Green Membrane is installed you will not have a high flow rate from the Silver port as it uses the back pressure of the tank not the incoming water pressure. There should be a small trickle of water.

What Would Cause Milky Colored Water?

If you have Air In The System it can cause Milky Colored Water. This is a normal occurrence with the initial start up of a Reverse Osmosis System. This milky look will disappear during normal use, normally within 1 to 2 weeks. If this condition reoccurs after your filter change, drain the tank 1 to 2 times.

What Would Cause the Water to Constantly Run or The Pump Won't Turn Off?

Any Crimped Tubing can cause Low / Slow Water Production. Make sure that all the tubing is straightened out as much as possible. If necessary replace the tubing.

 

With High Water Pressure make sure that your incoming water pressure does not exceed 100 psi. If it is a pressure relief valve may be necessary.

 

A Faulty Pressure Switch can cause your pump to run continually or not at all. To test, close the ball valve on your Tank, then open the Faucet for a few seconds to depressurize the system, then close it. The Pump should activate, wait a minute or two for the System to turn off and stop the pump. If the System stops running you need to check if you have High or Low Air Pressure in the Tank, you will need to follow the step-by-step instructions located in (What Would Cause Low / Slow Water Productions?). If the System does not stop running then verify that your Pump Assembly is working properly you will need to follow the step-by-step instructions located in (What Would Cause Low / Slow Water Productions?). Perform the tests here to check your other electrical components.

 

To test for a Missing or Bad Flow Restrictor, you will need to follow the step-by-step instructions located in (What Would Cause Low / Slow Water Productions?).

 

A Damaged ASOV (Automatic Shut-Off Valve) can cause Low / Slow Water Production as it will cause the tank to not fill properly. To test for a damages ASOV you will need to follow the step-by-step instructions located in (What Would Cause Low / Slow Water Productions?).

Why Won't The Pump Turn On?

You may not have Power To The Outlet. Make sure the electrical outlet is not controlled by the garbage disposal switch. If so switch to a different outlet.

Power to the RO Pump Test

The Transformer May Be Burned Out due to the Pump trying to pull extra amperage because of Clogged Filters. If the pump is not working, test the Transformer to make sure it is outputting 24 volts, if it doesn't replace the transformer. If a volt tester is not available, disconnect the Transformer from the Pressure Switch and test it by connecting it directly to the Pump and then the Solenoid. If the pump does not run then the Pump may be bad. Test your Solenoid the same way, it should click for only a second confirming its working. Should both the Solenoid and Pump not receive power then you may have a bad transformer.

 

Make sure all Electrical Connections are connected securely and not loose. These connections would include the Controller, Wire Harness, and Solenoid.

Why Would There Only Be a Small Amount of Water in the Storage Tank?

When Starting Up Your System whether it is for the first time or after your system maintenance, it can take up to 4 to 6 hours for the tank to fill.

 

To test whether you have High or Low Air Pressure in the Tank, you will need to follow the step-by-step instructions located in (What Would Cause Low / Slow Water Productions?).

Why Would There Be Low Water Flow From the Faucet?

Test to see if you have High or Low Air Pressure in the Tank, you will need to empty all the water from your storage tank. In order to do this shut off the main water supply and open the RO Faucet until the water stops running. Then check the pressure using a Digital Air Gauge for the best results.

Why Would There Be Noise Coming From The Pump?

The Booster Pump will vibrate causing the Pump to Vibrate Against Adjacent Objects when not in the optimum location. Make sure the pump is attached to the bracket and standing on the rubber feet at the bottom of the bracket. If the pump is hanging on the wall we suggest adding padding, such as foam, between the bracket and wall to dampen the vibration.

 

If the Pump Has Been Damaged it will need to be replaced.

What Would Cause Hot Water Coming From the RO System?

If you are receiving Hot Water from your Reverse Osmosis System then the RO System is too close to the hot water heater. Make sure the System is at least 25' away from the hot water heater.

What Would Cause a Leak at the Fitting?

This could be an issue with either the Fitting or the Tubing. Pull the tubing out of the fitting, if the tubing does not look damaged then re-insert it making sure to fully insert the tubing into the fitting. If there is still a leak, cut the tubing 1" and re-insert it. If the leak continues replace the tubing.

What Would Cause the Water to Have an Unpleasant Taste?

An Unpleasant Taste can come from not Changing Your Filters on time. Performing the Annual Sanitization during the Annual Maintenance will help eliminate the Unpleasant Taste in the Water.

 

If your Reverse Osmosis System has not been in use for an Extended Period of Time (More Than 2 Months) and you have not performed the Procedure for Extended Non-Use prior to your absence, then you will need to replace all filters and sanitize your system.

What Would Cause A Leak In A Faucet?

If you have Damaged, Faulty or Dried Out O-Ring in the lower faucet assembly's ¼” Blue Quick-Connect fitting this can cause your faucet to leak. Lubricate the Blue Quick-Connect fitting's O-Ring and reinstall the ¼” Blue tube. If the leak persists you will need to replace the lower faucet assembly.

Why Would the TDS Levels be High?

The Reverse Osmosis System flushes out the waste/brine water to the Hot water Adapt-A-Valve™ under the sink. If this Adapt-A-Valve™ to the Hot Water Outlet is Turned Off this can cause your Membrane to go Bad, Clog your Filters, and Create Higher TDS Levels. Verify the Adapt-A-Valve™ is turned on and the pump is working properly. Follow these Instructions to check for Clogged Filters.

You can contact us at 1-800-752-5582 or email us at WeCare@WattsWater.com and we will get back with you as soon as possible.

 

Caution - Not recommended for use on homes equipped with tank-less water heaters. Contact Premier for specific details regarding this unit and tank-less water heaters. System was tested in a laboratory setting utilizing a hot water heater of 40 gallons set at 120º F. Performance may vary if your heater is smaller than 40 gallons or set above 120º F, contact the manufacturer for additional details. System should not be used on homes equipped with a backflow prevention on the hot water heater. This device is 100% efficient, as no water is lost to drain in the production of the RO water.

Drill A Hole For The Reverse Osmosis Faucet

Caution - For Marble Counter Tops we recommend contacting a qualified contractor for drilling a hole. Most sinks are Pre-Drilled with a 1 ¼" diameter hole that you can use for your RO faucet. (If you are already using it for a sprayer or soap dispenser, see Step #1 below). Porcelain Sinks are extremely hard and can crack or chip easily. Use extreme caution when drilling. Watts accepts no responsibility for damage resulting from the installation of the faucet. A Diamond tip bit is recommended.

Step 1 - Determine desired location for the RO faucet on your sink and place a piece of masking tape over where the hole is to be drilled. Mark the center of the hole on the tape.

Step 2 - Using a variable speed drill set on the slowest speed, drill a ⅛“ pilot hole through both porcelain and metal casing of sink at the marked center of the desired location. Use lubricating oil or liquid soap to keep the drill bit cool (If drill bit gets hot it may cause the porcelain to crack or chip).

Step 3 - Using a 1 ¼” diamond tip hole saw, proceed to drill the large hole. Keep drill speed on the slowest speed and use lubricating oil or liquid soap to keep the hole saw cool during cutting.

Step 4 - After drilling, remove all sharp edges and make sure the surroundings of the sink are cooled before mounting the faucet.

Monitored, Top-Mount Twist Faucet Installation

The RO Pure Plus Faucet is equipped with quick connect fittings for easy tube installation. To make a connection, the tube is simply pushed into the fitting. The unique locking system holds the tube firmly in place without deforming it or restricting flow. Use the steps below in reference to any quick connect tube connections. Note - Make sure the tube is inserted the full ¾” into the fitting. Follow the below steps to complete the installation.

Step 1 - Locate the ¼” Blue tube that is already connected to the filter lid, labeled “Faucet” and feed it up through the pre-drilled faucet hole. Connect it to the ¼” Blue quick-connect fitting on the lower faucet assembly of the faucet. Make sure the tube is inserted the full ¾” into the fitting.

Step 2 - Make sure the Locking Tabs are “tucked”. Feed the tubes and the lower faucet assembly through the mounting hole in the sink. Test fit faucet placement.

Step 3 - Make sure the lower faucet assembly is seated properly inside of the rubber washer groove. Note - Arrow on base indicates FRONT of faucet.

Step 4 - Using a Phillips screwdriver, tighten the two screws until snug. Then, tighten each screw alternately until faucet is secure. Do not over tighten!

Step 5 - Inspect O-rings on lower faucet assembly. Lubricate with water-soluble lubricant if needed.

Step 6 - Align the release button on the back of the upper faucet assembly approximately 45° left off the back of the lower faucet assembly.

Step 7 - Press the upper faucet assembly firmly on-to the lower faucet assembly and twist clockwise until locked into place. Remove battery cover on faucet handle, pull battery tab and replace battery cover.

This is where you connect the Booster Pump which is the heart of making the system a ZeroWaste® System.

Caution - Water supply line to the system must be from the cold water supply line only. Hot water will severely damage your system.

Step 1 - Location the ¼” Green tube in the parts bag. Insert one end of the green tube into the plastic Adapt-A-Valve™ that is attached to the cold water supply.

Note - Make sure all tubes are pushed in all the way to the tube stop.

Step 2 - ¼” Green tube Adapt-A-Valve™ to Pump - Insert the open end of the ¼” Green tube from the Cold Water Adapt-A-Valve™ into the quick-connect fitting on the inlet (right) side of the booster pump. (See Diagram)

Step 3 -¼” Green tube Filter Lid to Solenoid - Insert the ¼” Green tube from the RO Module (Labeled “Cold”) into the Open quick-connect fitting on the solenoid (See Diagram)

Note - The pressure switch can be installed in either direction.

Step 4 -¼” Blue tube Filter Lid to Pressure Switch - Insert the ¼” Blue tube from the RO System (Labeled “Tank”) into the quick-connect fitting on the pressure switch.

Step 5 -¼” Blue tube Tank to Pressure Switch - In the parts bag, locate the ¼” Blue tube and insert one end into the open quick-connect fitting on the pressure switch.

Step 6 - Locate the wire harness and transformer in the parts bag. Connect the wire from the transformer to pressure switch. Connect the wire harness to the pump, pressure switch and solenoid to the corresponding color.

Caution - Do not plug in the transformer (plug) into the outlet yet.

Watts Premier Zero Pure Plus Reverse Osmosis Installation

After completing the successful installation of your Top-Mount Twist Faucet, Adapt-A-Valve™ and Booster Pump assembly you are prepared to finish the remainder of the installation for your Watts Premier Zero Pure Plus. Follow these steps to complete the installation and get your New Reverse Osmosis System up and running.

Step 1 - Locate the ¼” Red tube that is already connected to the back of the filter lid and connect the open end into the HOT water return Adapt-A-Valve™. Make sure the tube is pushed in all the way to the tube stop.

Caution - The Flow Restrictor is installed inside of the red tube at the bent end. DO NOT REMOVE THE FLOW RESTRICTOR OR CUT THE RED TUBING AS IT WILL DAMAGE THE FLOW RESTRICTOR.

Zero Pure Plus Install

Step 2 - Determine best location for the RO module to be mounted to allow for future system maintenance. The parts bag has 2 self tapping screws. Using an electric drill with a Phillips bit, screw them into the cabinet wall 6” apart and 16” from the bottom of the cabinet. Note - Do not cut any RO System Tubes at this Time.

Step 3 - Teflon tape must be applied in a clockwise direction. Wrap (7 to 12 turns) around the male pipe threads (MPT) on the stainless steel fitting on top of the tank.

Step 4 - Thread the quick connect ball valve (supplied in the parts bag) onto the stainless steel connector on the tank. Note - Do not over tighten the plastic connections.

Step 5 - Position tank in desired location. Stand it upright or lay it on its side (using the black plastic stand). Measure the blue tube (marked “TANK”) from the RO module to the tank and cut it to length leaving a straight, square edge. Insert the tube into the quick connect fitting on the tank ball valve. Make sure the tube is pushed in all the way to the tube stop. Note - Set the blue ball valve knob in-line with the blue tube, this is the “open” position.

Starting Your New Reverse Osmosis System

Caution - To prevent the possibility of electrical shock, clean up any water on the cabinet floor and dry all water from outside of the Reverse Osmosis System.

Step 1 - Turn on the incoming cold water at the angle stop valve and the Adapt-A-Valve™. Check the system for leaks and tighten any fittings as necessary. (Check frequently over the next 24 hours to ensure no leaks are present).

Caution - If you have connected your RO system to a refrigerator / ice maker, make sure the ice maker is off (do not allow water to flow to the ice maker) until flushing (Step #4) is complete and the tank has been allowed to fill completely. Connection from the RO to the ice maker system should have an in-line valve installed before the ice maker so it can easily be closed to prevent water flowing to the ice maker during start up and periodic maintenance. Your storage tank must be allowed to fill up fully in order for the ice maker system to work properly.

Step 2 - Plug the transformer into the electrical outlet under the sink.

Note - If the pump doesn’t start, make sure there is power at the electrical outlet and that it is not controlled by the garbage disposal switch. If the Booster Pump turns on and the water starts to drip out of the RO Faucet you will need to connect the system to a different power outlet.

Step 3 - Make sure the ball valve on the tank is open

Step 4 - Open the RO faucet and leave it open until water begins to trickle out (this may take a few minutes and the water will come out slowly).

Step 5 - Close the RO faucet allowing the storage tank to fill with water. It may take 2 to 4 hours to fill the tank completely depending on the production capability of the membrane, local water temperature and water pressure. 

Note - During the fill period you may hear water trickling which is a normal occurrence.

Step 6 - After the storage tank has filled open the RO Faucet to flush the tank completely. You will know that the tank is empty when the flow rate from the RO faucet is down to a trickle. Repeat this step two more times. The fourth tank can be used for drinking. 

Note - Flushing of the tank 3 times is only necessary during the initial startup and after replacing the membrane. The flushing process should take about a day to complete. Water may be cloudy or milky due to air in the system and carbon particles flushing out of the final polishing filter. This condition will resolve itself after flushing a couple of tanks of water.

Watts Premier wants to make sure you are aware just because you cannot taste it, does not mean that it is not there. Contaminants such as Lead, Chromium and Arsenic are undetectable to the taste. Additionally, over time if you do not replace the filters, other bad tastes and odors will be apparent in your drinking water. It is important to change out your filters at the recommended intervals as indicated below. When replacing the filters, pay special attention to any cleaning instructions. If you have any questions throughout the process you can contact us at 1-800-752-5582 or email us at WeCare@WattsWater.com and we will get back with you as soon as possible.

System Overview

Water quality concerns are becoming more of a focus for the public. You may have heard about contaminants in the drinking water such as Arsenic, Chromium, Cryptosporidium or Giardia. There may also be some local water issues such as high levels of Lead and Copper. This Premier RO Pure Plus Reverse Osmosis system has been designed and tested to provide you with high quality drinking water for years to come. The following is a brief overview of the system. Your Reverse Osmosis System is a four stage RO which is based upon separate treatment segments within the one complete water filtration system. These stages are as follows:

Stage 1 - Five Micron Sediment Filter (WP105311) that traps sediment and other particulate matter like dirt, silt and rust which affect the taste and appearance of your water. Note - Recommended Change Every 6 Months.

Stage 2 - Five Micron Carbon Block Filter (WP105351) which helps ensure that chlorine and other materials that cause bad taste and odor are greatly reduced. Note - Recommended Change Every 6 Months.

Stage 3 - 50 GPD (Gallons Per Day) RO Membrane (WP105331).This semi permeable membrane will effectively remove TDS, Sodium and a wide range of contaminants such as Chromium, Arsenic, Copper, Lead as well as Cysts, such as Giardia and Cryptosporidium. Because the process of extracting this high quality drinking water takes time, your RO water treatment system is equipped with a storage tank This Reverse Osmosis Membrane is critical for effective reduction of total dissolved solids (TDS). Note - Recommended Change Every 3 to 5 Years.

Stage 4 - VOC (Volatile Organic Compound) Carbon Block Filter (WP105381). Through the specialty (VOC) like MTBE’s, Atrazine, Benzene, 2,4-D,Lindane and others from your drinking water. It is estimated that VOC’s are present in one-fifth of the nation’s water supplies. These water contaminants can enter ground water from a variety of sources including localized use of herbicides and pesticides, gasoline or oil spills, leaking underground fuel tanks, septic system cleaners, and chemicals used in the dry-cleaning industry. Premier RO-Pure Plus system conforms to NSF/ANSI 58 for VOC reduction. See performance data sheet for individual contaminants and reduction performance. Note - Recommended Change Every 12 Months.

Filter Kits

Bi-Annual Filter Kit - WP531102 - This kit contains one sediment Filter (WP105311) and one Pre-Carbon Filter (WP105351).

Annual Filter Kit - WP531109 - This kit contains two Sediment Filters, (WP105311), two Pre-Carbon Filters (WP105351) and one VOC Carbon Block Filter (WP105381).

Four Pack Filters - WP531160 - This kit contains one Sediment Filter (WP105311), one Pre-Carbon Filter (WP105351), one VOC Carbon Block Filter (WP105381) and one 50 GPD Membrane (WP105331).

Six Pack Filters - WP531161 - This kit contains two Sediment Filters (WP105311), two Pre-Carbon Filters (105351), one VOC Carbon Block Filter (WP105381) and one 50 GPD Membrane (WP105331).

Changing The Filter Cartridges

Your Reverse Osmosis Module is equipped with valve heads which will automatically turn off the water supply to each filter when the filter is released, thus you do not need to turn off the incoming water supply at the Adapt-A-Valve™. The RO faucet must be off when filters are replaced. To make the removal of the filter cartridges easier, the heads and cartridges may be swiveled up to 90° as shown in the pictures below.

When preforming your Bi-Annual System Maintenance you will be replacing your Sediment Filter (105311) and Carbon Pre-Filter (WP105351). Complete these same steps for the Annual System Maintenance. The only difference will be in addition to replacing your Sediment Filter (WP105311) and Carbon Pre-Filter (WP105351) you will also be replacing your VOC Carbon Block Filter. (WP105381). Note - Flush the first full tank after completing the Annual Maintenance.

Step 1 - Place a towel under the RO module to catch any excess water that may drip out from the filters during the changeover.

Step 2 - To Remove A Filter Cartridge: Push and hold the button on the valve head above the filter. Pull the cartridge downward (from the head) to remove. Release button and discard the old filter.

Step 3 - To Install A Filter Cartridge: Remove the seal cap and insert the cartridge into the valve head until you hear an audible “Click” (the button doesn't need to be pressed to install new filters).

Note - You must reset the faucet monitor. After completing your 6 Month Maintenance it is a good time to check the air pressure in your storage tank

Zero Pure Plus Filter Replacement

Membrane - Your Membrane (WP105331) is only changed every 3 to 5 Years, depending on the incoming water conditions and the amount the Reverse Osmosis System is used. This Reverse Osmosis Membrane is critical for effective reduction of total dissolved solids (TDS).

TDS - The water output should be tested periodically to verify that the system is performing satisfactorily. Premier does have TDS Meters available for purchase as well as a TDS Calculator for you to monitor your TDS levels. Premier recommends replacing the membrane when TDS reduction falls below 75%. Normally, a membrane would be replaced either during a Bi-Annual or Annual Filter change. However, if at any time you notice a reduction in water production or an unpleasant taste in the Reverse Osmosis water, it could be time to replace the membrane.

Annual Sanitization

Caution - Do Not change your Post-Carbon Filter until the sanitization has been completed. The Pre-Filters and Membrane can be changed before the sanitization. If you have connected your Reverse Osmosis System to a Refrigerator or Ice Maker, make sure the connection has been turned off. Do Not re-open the connection until the sanitization process is completed.

Step 1 - Turn off the water supply to your RO system at the Adapt-A-Valve™ and open the RO faucet to drain the storage tank.

Step 2 - Locate the tube that runs between your filter module and the storage tank and disconnect at both ends. Drain any remaining water in the tube.

Step 4 - While covering one end of the tube with your finger, insert the other into the tank. Then insert the open end into the filter module.

Step 5 - Turn the incoming water back on and let the system fill for approximately 10 minutes.

Step 6 - Turn off the incoming water and let the system sit for 1 minute.

Step 7 - Drain the system completely and then follow the startup procedure - filling then draining two full tanks of water.

Step 8 - Replace the post-carbon filter once complete.

Faucet Indicator Battery Replacement

This faucet is equipped with a filter change indicator. The indicator light will flash Blue while the water is being dispensed. After approximately six months or 2,000 gallons of filtered water being used the light will change to Red, indicating that filters should be changed. After filter change you must reset the monitor. To change the indicator battery follow the below instructions.

Step 1 - Turn the handle on the storage tank ball valve to the “off” position and lower faucet handle to “on” position.

Step 2 - Remove the faucet handle cover at the slot. Note - Water will dribble out of the spout, use caution when handling the electronic components.

Step 3 - Slide the old battery out and replace with new battery. Note - Once the battery is pushed into the clip a red and blue light will flash indicating proper installation.

Step 4 - Replace cover assembly onto the faucet handle while aligning the tab on the cover with the notch on the faucets handle.

Check Air Pressure In The Tank & Re-Pressurize

Note - Check the air pressure only when the tank is empty of water. Check air pressure in the storage tank when you notice a decrease in available water from the RO system. Air can be added with a bicycle pump using the schrader valve that is located on the lower side of the tank behind the blue plastic cap. Follow the steps below:

Step 1 - Turn off the incoming water supply to the Reverse Osmosis System.

Step 2 - Open the RO Faucet and allow water to drain from the tank until it is completely empty. Note - When water from the RO faucet slows to a trickle, with the faucet still in the open position, you may add air to the tank to purge any left over water, this will ensure that the tank is completely empty.

Step 3 - Once all water in the tank is purged, check air pressure using an air pressure gauge, it should read between 5 to 7 psi. For best results a Digital Air Pressure Gauge (161000) or Tire Pressure Gauge is recommended.

Step 4 - If your tank is not set between 5 to 7 psi, you will want to Re-Pressurize the tank using a tire pump or other means which will not rupture the bladder.

Caution - It is not recommended to use an air compressor as it is to easy to rupture the bladder in your tank. If you have connected your RO system to a refrigerator / ice maker, make sure the ice maker is off (do not allow water to flow to the ice maker) prior to Re-Pressurizing your tank.

Note - If their is air and sputtering coming from the faucet or water coming out of the Schrader Valve, that is an indication that the bladder in the tank has ruptured. You will need to replace the tank.

Step 5 - Start up your system. See Installations for Instructions.

Procedure For Extended Non-Use (More Than 2 Months)

To prepare your Reverse Osmosis System for your extended leave turn off the water supply to your RO system at the Adapt-A-Valve™ and open the RO faucet to drain the storage tank. Once the storage tank is empty, remove all filter cartridges (order not important). Place them into a sealed plastic bag and store in your refrigerator. Note - Do Not Place In The Freezer. To restart your Reverse Osmosis System follow the below steps.

Step 1 - Re-install all filters on to the RO unit. Filters are color coded to match the filter heads they snap in to.

Step 2 - Turn on water supply to the system at the Adapt-A-Valve™. Note - Check frequently over the next 24 hours to ensure no leaks are present.

Caution - If you have connected your RO system to a refrigerator / ice maker, make sure the ice maker is off (do not allow water to flow to the ice maker) until the tank has been allowed to completely fill.

Step 3 - Open the RO faucet and leave it open until water begins to trickle out (it will come out slowly).

Step 4 - Close the RO faucet allowing the storage tank to fill with water. It may take 2 to 4 hours to fill the tank completely depending on the production capability of the membrane, local water temperature and water pressure.

Step 5 - After the Tank has filled, open the RO Faucet to flush the tank completely. You will know that the tank is empty when the flow rate from the RO faucet is down to a trickle. The second tank can be used for drinking.
