ASV-4000Q RO Automatic Shut Off Valve 1/4" Quick Connect

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-4000Q stops this by shutting off incoming water at a certain pressure. Outfitted with quick connect fittings.
