This valve protects your water heater, pipes, and fixtures from burst lines and premature failure caused by excessive pressure.\u003c\/p\u003e\n\n\u003cp style=\"margin-bottom:16px;\"\u003e\u003cstrong style=\"color:#dc2626;\"\u003eQ: Where does this valve install on my RV?\u003c\/strong\u003e\u003cbr\u003e\nA: This reducing valve installs inline between your fresh water hose and the RV's city water inlet connection.

Many RVers prefer lower pressure settings (10-15 PSI) to extend the life of their water system components.\u003c\/p\u003e\n\n\u003cp style=\"margin-bottom:16px;\"\u003e\u003cstrong style=\"color:#dc2626;\"\u003eQ: Can this valve be used with both hot and cold water lines?\u003c\/strong\u003e\u003cbr\u003e\nA: This valve is designed for cold water inlet regulation.
