I had purchased my own reverse osmosis system and whole home filter from max water flow and the quality was horrible. After the units were installed by another company eco water systems, they leaked like crazy. I called WaterMart because they advertised using high quality fittings which I now realize is very important. The installation and repair done by WaterMart was first class. The tech used sterile latex gloves when handling the filters and canisters, replaced all my joints and connectors with high quality ones that don't leak and even installed a leak detector to shut down the water supply if a leak does happen. WaterMart listened to my concerns and went over and above in their service. Highly recommended.
