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.
