ISpring Reverse Osmosis Automatic Shut-Off Valve – Quick-Connect 1/4" ASV AAS2 For RO Systems

About This Product

If your reverse osmosis system keeps running water to the drain even when the tank is full, the automatic shut-off valve might be the culprit.

This iSpring ASV is designed to do exactly what it says – it shuts off the water supply once the tank pressure hits about 65% of the incoming water pressure.

That's a smart little feature that saves water and keeps your system from overworking.

It comes with 1/4-inch quick-connect fittings, so installation is pretty simple – just match the "in" and "out" markings on the top and bottom.

The top side handles the high-pressure line from the filter housings, and the bottom side connects to the membrane and the tank.

It's compatible with most RO systems on the market, which is great if you're replacing a worn part.

Just keep in mind that if your drain issue persists, it could be the check valve, flow restrictor, or tank pressure – but this ASV is a solid first step to fix things up.
