DIGITEN 1/4" Auto Shut Off 4 Way Valve for RO Reverse Osmosis System Water Filter System

Did the job it was designed for

The old auto shot off valve one was making strange noises, loud rattling sound while resonating. After a while something broke in it and the water was barely flowing. I have picked up this one, installed it in half an hour, and the solved the problem. Gave a new lease on life to my water filtration system.

Works as it should.

I am very impressed woth this little device. I used it for my teverse osmosis system to stop the flow once the tank is full. Works exactly as expected. Saves me loads of water.

Does the job. All as described.

Dry cleaver device

Worked only for 7 months! Bought a different brand & hoping that works for at least a year. New ASO fitted, now water is filling the tank and not going down the brine line 24/7.

Good

Update to my old Reverse Osmosis system. Old ASO worked, but who knows how well or long. Change this ASO along with the Membrane and drain restrictor.

Basic ASO valve, works as expected. Can't speak to the actual pressures that trigger the valve as I didn't measure them, but it seems to be standard. If you have an RO system with a mechanical float in the tank that plugs the output tube and develops backpressure that way (like on an office water cooler), the minimum pressure differential may not ever be reached to trigger the valve and shut off the flow, and it might cause it to flutter or make a loud and annoying buzzing sound. Your RO membrane will continuously pump out wastewater, obviously a major problem. A fix for this is to run the wastewater output through the high pressure side of the ASO valve (side that says In and Out, not the side with the screws) instead of the feed water going into the RO membrane like the typical configuration requires. Wastewater comes out at a lower pressure than incoming city/well water, so the difference between wastewater and clean RO output water will be closer, and the valve will actually open and close quickly like it should. It's not a perfect fix, since running high-TDS wastewater through the ASO valve will make it gunk/mineralize up faster. But they're dirt cheap to swap out, and it definitely beats the hassle of retrofitting a solenoid and electric float switch into a setup that wasn't designed for it.

Aun sin poder opinar sobre su duración, lo cierto es que funciona perfectamente y el equipo de ósmosis inversa ha vuelto a funcionar sin los problemas que tenía con la válvula anterior, que era la de serie del equipo. El envío, como siempre, muy rápido y sin problemas.

Good price.

Diese Teile passt genau. Wir sind zufrieden. Danke
