Swapping an old inlet is straightforward with Valterra RV water inlets built for city water or gravity fill setups. Choose plastic or metal styles, with available brass check valves and lockable hatches to fit your needs. For a clean fit, compare your cutout and flange depth, and match your interior thread type (male or female) and fittings for pex.
Yes, with the right fittings. You can use common adapters for PEX; some installs used push-fit style connectors. If threads are plastic, tighten carefully to avoid stripping and support the inlet to prevent the 1/2" MPT section from rotating. If a flat, unbeveled port won't seal with a rubber ring, use plastic-compatible plumber's putty instead of tape.
Some Valterra inlets include a check valve and others do not. Verify the listing for a built-in brass check valve if you need backflow prevention. If replacing a unit that groans or leaks at partial flow, a new inlet with a check valve can help. Add an elbow or leader hose at the connection to reduce wear on the fitting.
Pick metal for a recessed, durable flange look, or plastic for a lighter, simple replacement. Some metal-flange options note a 2-3/4" recessed flange. If you want better UV appearance, black components can help resist stains versus white. With plastic threads or caps, tighten gently and check the cover fit to avoid looseness over time.
Often yes, but confirm dimensions first. Compare your opening to listed specs like a 3-1/2" cutout or a 2-1/2" depth from flange to barb on some options. A larger faceplate can cover an original or slightly enlarged hole. If the inside box is smaller than your original, expect a tighter hand space around the cap.
