Product Description
Reverse Osmosis Water Filter Automatic Shut-Off Valve with Quick-Connect fittings, 1/4"
The "in & out" markings are on the top of the valve. The top side of the valve is the high pressure side and the bottom side is the low pressure side. The high pressure from the filter housings goes to the "in" on the top of the valve. Then the high pressure "out" goes to the membrane housing inlet. The membrane housing low pressure outlet connects to the "in" on the bottom side of the valve. The "out" on the bottom goes to the tank.
Note: Continual drain problem can be caused by different factors, including automatic shut-off valve, check valve, flow restrictor, or tank pressure. Replacing the ASV may not help if the problem is caused by other factors.

We had a problem where the shut off was stuck open. This a easy replacement. Works great.

We had a problem where the shut off was stuck open. It is a easy replacement. For a complete rebuild get the check valve and flow restrictor as well.

I bought this item in Jan of 2015. So far it works pretty good. This is an easy install part and dont need any licensed plumber. The seller is very kindly and even followed up with me 9 months later. I would recommend it.

The one that came with the water filter system broke only after 5 months. I got a replacement and that one lasted longer, for a year and 8 months. Well see how long the new one will last. As for how the device functions and the installation with the quick connect, it is great. Durability not as good.
