The system utilizes the TwinFloSXT (8500) twin meter and control valve made by Fleck to initiate and control backwashing and regeneration cycles. We are pleased to offer replacement valves:

We have heard many complaints from AQUAtiva™ water filter system owners regarding the high price of original equipment AQUAtiva™ replacement filters. The good news is that the replacement filters and components for AQUAtiva™ whole house water filters, and reverse osmosis water filter systems are standard sizes, and we have many affordable, high quality replacement cartridges available. In fact, in many cases, our cartridges are the very same filters, made by the same manufacturer as the AQUAtiva™ replacement cartridge, for a fraction of the price! You can rest assured that our compatible replacement filters are of the highest quality - they are made by Pentek Filtration of Wisconsin, USA, one of world's largest water treatment products manufacturers.
