          • Q:

            Replacing water lines in 30yr old RV with Pex. Need one way valve in two locations, supply line from fresh water tank and supply line from City water connection. Can this valve be used in potable water system for RV? Thank you.

              These valves do not have NSF approvals, so they are not suitable for use in potable water lines.
