Sized for straightforward swaps, these RV water inlets use a 2-3/4 inch diameter flange for a neat, covered opening. Choose metal or brass parts for durability—aluminum flanges handle salt air well—while plastic options are available too. Confirm your interior connection is 1/2" FPT or 1/2" mpt and decide if you want a check valve, then pair with a 3/4" garden hose hookup outside.
Use the included sealant, tape, screws, or adapter if provided, and snug fittings without over-torquing. When tightening a 1/2" adapter, hold the plastic 1/2" MPT portion to keep it from rotating. In freezing weather, drain water trapped between the anti-backflow valve and tank flush valves to help prevent cracking.
Some do, and some use brass while others use plastic. Verify whether the check valve is brass or plastic and match thread types carefully; brass female to plastic male seals, but plastic female to brass male can leak. If you have leaks, recheck thread compatibility and use thread tape or sealant as directed.
An aluminum flange is highly rust resistant and in saltwater it basically does not corrode at all. If you want durability at the hose end, metal threads can help prevent stripped fittings, while fully synthetic designs avoid rust and corrosion. For sun and stains, black parts can stand up to UV and mildew better than white.
Match it to your RV's water line connection. Check if your setup needs a 1/2" FPT or a 1/2" MPT on the inside of the inlet. Also confirm the outside is set for a standard 3/4" garden hose connection if you use city water.
It can, but it isn't a universal fit. Measure your opening and check that your housing will accommodate a 2-3/4 Inch Diameter Flange. Confirm the flange will cover any gaps around the hose connection. If your current housing is tight, verify clearance so the flange can sit flush and seal properly.
