Automatic Shut off Valve (ASO) for Reverse Osmosis Systems

Our ¼” Quick Connect ASO allows your system to turn off the water supply when the tank pressure reaches approximately 65% of the supply water pressure. When you have a tank full of clean water and the waste water didn’t shut off this might be an indication to change your ASO Valve. Other indications are:
ASO rupture or burst – which can cause pure water to mix with tap water.
ASO leak and water can’t get through all the valve causing water channels to plug

Remark: Continual drain problem can be caused by different factors, including automatic shut-off valve, check valve, flow restrictor, or tank pressure. Replacing the ASO may not help if the problem is caused by other factors.

Rated 4 out of 5 by nlk from ASO valve I recently had the ultimate RO perm system installed. The TDS was not stable, it would increase to 80 or more over 5 - 6 days after draining and refilling the tank. The techs at APEC told us order an Auto shut off valve which I had installed in the water line. This has corrected the unstable TDS, the numbers are now consistently under 20.

Rated 1 out of 5 by Shedding from Keeps shutting my water down This is the second Shut Off Valve that goes bad for me. I've ordered 3 because I really don't want to be without water. After troubleshooting my system, it always seems to point to this little guy. I wish it was designed a bit better.

Rated 5 out of 5 by ACLOW from Awesome quick fix After consulting with APEC customer service, we figured out that my auto shut-off valve wasn't working any more. For $10 this was a quick fix that worked great. Took me two minutes to replace. A++
