    What Would Cause Low / Slow Water Production?

    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.

    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.

    If you had a prior Reverse Osmosis System make sure that you did not use the Old Adapt-A-Valve™ from this prior system. Install the Adapt-A-Valve™ which was supplied with your new RO system or purchase a new one.

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

    Watts Premier Zero Pure Plus Reverse Osmosis Clogged Filter Troubleshooting

     

    To check for Clogged Filters and/or Filter Head turn off the valve at the top of the tank and check water production from the faucet. The system should produce at least 3 to 4 ounces (89 to 118 mL) per minute with the tank off. If it is producing less, check for Clogged Filters or a Bad Membrane by following these instructions. Prepare a towel and a large bowl. Close the Tank Ball Valve and Open your Faucet so that it will drip. Remove the Red Filter (105311), with the water on and the system connected. Place your little finger into the Red Filter Port and depress the valve. Caution - Water will come spraying out at a good rate. Take care to keep any water away from your electrical components. If you do not get water, turn off the water and remove the Green Tubing from behind the Red Filters Port. Place the end of the tubing into a cup and hold it, then slowly turn on the main water supply. If the water does not come through you may have a problem with your shut-off valve. If you get water, continue testing with the remaining filters using the same steps as the Red Filter (105311). If your get slow water flow during your testing of the Green Filters Port, remove the Yellow Filter (105351) and place the Silver Filter (105381) into the Yellow Filters Port and then re-test. The Silver Filters Port will naturally have slower flow than the other filters as it goes through the Membrane (105331). If you have no flow through the Silver Filters Port then install the Silver Filter (105381) into the Green Filters Port and re-test. If the Silver Filter Port did not have any/or low water flow during the testing, but the Red and Yellow Filter Ports passed the testing you may have a clogged lid. Water should flow through unrestricted while testing if not you should replace the filter(s). Note - If you find that your membrane is bad you will also need to make sure the hot water return Adapt-A-Valve™ has been turned On.

  •  

    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 your Reverse Osmosis System and after changing your Membrane. 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 Water Pressure Regulator may be necessary.

    To check for Clogged Filters and/or Filter Head Turn off the valve at the top of the tank and check water production from the faucet. The system should produce at least 3 to 4 ounces (89 to 118 mL) per minute with the tank off. If it is producing less, follow these instructions to check for Clogged Filters or a Bad Membrane.

    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 here. If the System does not stop running then verify that your Pump Assembly is working properly. Perform the tests here to check your other electrical components.

    If you have a Missing or Bad Flow Restrictor your system may run for extended periods of time. Verify your flow restrictor is still in place and has not been removed. If the flow restrictor is damaged or missing you will need to replace it.

  •  

    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.

    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.

    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 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.

  •  

    What 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 the 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.

    Drill a Hole For The 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.

    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.

    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 Pressure Switch 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 Up Your New Reverse Osmosis System

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

    Step #1 - Turn on the incoming hot and 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 Zero 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 (105311) 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 Month.

    Stage #2 - Five Micron Carbon Block Filter (105351) which helps ensure that chlorine and other materials that cause bad taste and odor are greatly reduced. Note - Recommended Change Every 6 Month.

    Stage #3 - 50 GPD (Gallons Per Day) RO Membrane (105331) the heart of your Reverse Osmosis System.. 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. Note - Recommended Change Every 2 to 5 Years depending on your water quality.

    Stage #4 - VOC (Volatile Organic Compound) Carbon Block Filter (105381). 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.

  •  

    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 (105351). Complete these same steps for the Annual System Maintenance. The only difference will be in addition to replacing your Sediment Filter (105311) and Carbon Pre-Filter (105351) you will also be replacing your VOC Carbon Block Filter. (105381). 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.

    Membrane - Your Membrane (105331) is only changed every 2 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.

    Water Sample - You may send a water sample to Premier for a free diagnosis of your membranes performance. To send a water sample, use 2 clean containers and fill ½ cup of tap water in one container and ½ cup of RO water in another container. Clearly label each sample. Send the samples to 8716 W Ludlow Dr, Suite 1, Peoria, AZ 85381, Attention: “Water Samples”. Premier will test the water and mail or call you with the results.

  •  

    Annual Sanitization

    Note - 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.

    Watts Premier Annual Sanitization

    Step #3 - Hold both ends of the tube together with the ends pointed away from your face. Using a dosing syringe (see figure) slowly insert 1 teaspoon (5 mL) of common household bleach into the tube. Note - Do not use a needle syringe.

     

    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 - (A). 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 - (B).

  •  

    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 follow the below steps to ensure your RO System will perform as it did prior to you leaving.

    Step #1 - Unplug transformer from electrical outlet.

    Step #2 - Turn off the hot and cold water valves to your RO system and open the RO faucet to drain the storage tank. Once the storage tank is empty, remove all the filter cartridges (order not important). Place the filters into a sealed plastic bag and store in the refrigerator. Note - Do Not Place In Freezer

    To restart your Reverse Osmosis System follow the below steps.

    Step #1 - Reinstall all filters onto the Reverse Osmosis System. Filters are color coded to match the filter heads they snap into.

    Step #2 - Turn on the incoming hot and cold water angle stop valves.

    Step #3 - Turn both of the Adapt-A-Valves™ on and check the system for leaks and tighten fittings as necessary. Note - Check daily over the next week to ensure no leaks are present.

    Step #4 - Plug in the transformer into the electrical outlet.

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

    Step #3 - 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 #4 - 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.
