ASV-2000W RO Automatic Shut off Valve 1/4" QC for PuROTwist
This device is designed to save water that your RO system would otherwise send to the drain when the storage tank fills up. Normally RO systems continue sending rinse water to the drain when the tank is full, but the ASV-2000W stops this by shutting off incoming water at a certain pressure. Outfitted with quick connect fittings.
