This is the third Premier 531411 unit that I have purchased over the past 9 years. The first went into an off the grid Costa Rica second home with well water supply. The second is in my present home here in California. And the third unit has just been purchased for our new condo in Puerto Vallarta. Quite simply, these were the very best R.O. units that I could buy. The quality of the water is far superior to any bottled water that we have ever bought. You will not be disappointed.

I bought the 531411 RO with a ph balancing filter for my home. We live in San Diego and the city water is pretty nasty. This filtered water tastes amazing and the ph filter puts back in valuable minerals that the filter removes. We had a professional plumber install the unit because that stuff is beyond me, but it was easy for him and he installed it within 2 hours. I'm very glad I bought this product.
