The pump kept running and I was not sure if it was the pump switch or the shut off valve. I replaced both [Pressure switch and shut off valve] to get the Reverse osmosis system to work perfectly.

This was the third valve I installed and the water still did not shut off. Did some research and learned there are two shut off valves. The second is an elbow valve attached to the RO filter tube. Replaced that and shut off accomplished.

Replaced an oem part with a third party part. It didn't work, and while it wasn't working it made a lot of noise. My wife said it had to go. So, I bought the OEM part and all is well.... except I am out $10

I've had it installed several months now and so far no issues. No more water draining constantly. Easy to install.

Seemed to be a good match to the one I replaced. Be sure to either change one line at a time or to lable everything before you disassemble so the new one goes in correctly.
