Once again the team here at Flair-It has created a new industry changing fresh water valve. This new RV water heater bypass valve allows for our easiest installation yet. It works on 1/2″ PEX pipe, PE-RT pipe, and our new high pressure braided hose. Easily connect with our revolutionary PEXLOCK clamps, standard stainless steel clamps, or traditional copper crimp rings. This contractor pack includes two valves.
