14 stage water treatment replacement filter set
Terrence was a great help in working with me to determine the correct replacement filters I needed for my 14 stage water system. The shipment arrived in great shape and I studied the YouTube video from the link he sent me. I watched the step by step tutorial as I replaced each filter. It was what I needed to make the removal and installation smooth. The water is back to the proper freshness now.

Filter system and leak detection
Easy to install, we do ours every 2 years; with an exception if the city works on the pipes and causes debris in the water lines. I put a plastic rectangle container (like you buy to put pantry items in) under mine with a water sensor in case of a leak in any of the filters or lines.
