Steps
Turn off the city water hookup and switch off the RV water pump. Open the kitchen faucet to release pressure, then put a towel and a bucket under the sink.
Unbox the new faucet and lay out the parts. Check the supply lines and note the adapter you need, a 1/2 inch NPT to 3/8 inch compression fitting for RV plumbing.
Disconnect the hot and cold supply lines from the old faucet. Unscrew the mounting nuts underneath, using a basin wrench if space is tight, then lift the old faucet out.
Clean the sink surface and the mounting hole. Check that the new faucet base covers the hole and that the handle and pull-down hose clear the backsplash.
Thread the adapter onto the new faucet inlets and wrap the threads with plumber's tape. Hand tighten, then snug with a wrench without over tightening.
Feed the supply lines and pull-down hose down through the sink hole. Set the faucet in place and tighten the mounting nut from below.
Connect the supply lines to the RV water lines and tighten each fitting. Turn the water back on slowly and check every connection for drips.
Run the faucet on hot and cold, then pull the spray head out and let it retract to test the hose. Dry any drips and tighten fittings a quarter turn if needed.
Tips and common mistakes
Measure the space under the sink before buying, since a pull-down hose and large mounting nut need clearance.
Use plumber's tape on threaded metal fittings but not on compression ferrules.
Keep the old faucet until the new one has run leak free for a day.
Never force plastic RV fittings, because a cracked nut means a second trip to the store.
Questions
Do I need an adapter to fit a residential faucet in an RV?
Yes. Most residential faucets have 1/2 inch NPT inlets while RV lines are 3/8 inch compression, so you need a 1/2 inch NPT to 3/8 inch compression adapter.
Can I install any residential kitchen faucet in an RV?
Most single-hole models fit, but check the base size and the room under the sink for the pull-down hose and mounting hardware.
How do I check for leaks after the install?
Turn the water on slowly, run hot and cold, and dab each fitting under the sink with a dry paper towel. Tighten a quarter turn if you see a drip.
