When to Replace

Installation Tips

• Shut off the city water supply and depressurize the vehicle's plumbing system.
• Remove the old inlet by disconnecting the interior plumbing line and unscrewing the exterior flange.
• Thoroughly clean the mounting surface of old sealant and debris.
• Apply thread sealant tape to the 1/2" NPT male threads before connecting to the RV's plumbing.
• Apply a continuous bead of non-leveling RV sealant to the back of the new flange before mounting.
• Secure the flange to the vehicle with appropriate screws, ensuring a snug fit without over-tightening.
• Pressurize the system and carefully inspect for leaks at all connection points.
