About this item

Product details

This 1/4 inch Quick Connect Check Valve isolates the membrane from back pressure from the storage tank and provides a solid wall for the shutoff valve to push against. Without a properly working check valve, the RO system will not shut off properly when the tank is full, a great deal of water will be wasted, and eventually the membrane will be ruined.

Allows water to flow away from the RO membrane but not back toward it
Featured 1/4 inch quick connect fittings for easy installation
Manufactured using NSF-compliant materials
Saves thousands of gallons of water per year
Compatible with all APEC under-sink reverse osmosis systems

APEC Check Valve

Worked like a charm. If you're R/O system continuously drains water at the faucet then replace this part first.
