High Pressure Automatic Shutoff Valve
Upgraded High Pressure Automatic Shutoff (ASO) Valve. When back pressure builds due to the product line being full, the valve is activated and water is stopped from entering the RO membrane housing. Eliminate ASO chatter. Faster, quieter, and longer life than the standard ASO. *Must be used with check valve. See Files tab for installation diagram. This unit does not come with check valve.
