APEC RO Replacement Filters Complete Filter Set for ULTIMATE 90 GPD PH Reverse Osmosis 6-Stage Systems (Stages 1-6) - With 1/4"D Tubing

My wife loves her RO water for her coffee

During a remodel several years ago, I had the plumber add the additional 1/4 water line and valve. Drill the granite counter top and drill the drain line for the RO waste water. Once it was in it works great. With filters parts do where out and if you're DIY'er it should no trouble to update the filters. I did overlook these rings the second time i changed the RO filter and took some time to find the right stuff. Eventually found everything I needed and finished it up leak free.

The water is so good we have had it for almost 10 years now. Thank you for a great product!!

I have used my system for years and have always been happy with the way it functions to give me good drinking water!
