Plumbing & Water

An RV has three separate water systems, and most plumbing problems trace back to one of them. Fresh water runs from the city inlet or onboard tank through the pump and out to your fixtures. Gray water drains from sinks and the shower. Black water handles waste from the toilet.

Fresh water plumbing is the largest part of this range, covering PEX fittings from Flair-It and Watts, pumps from SHURflo and Seaflo, faucets, shower heads, hoses, regulators, and filters. Black water plumbing covers waste valves, sewer hose fittings, tank flush components, and gate seals, mostly from Valterra and Camco. Tank chemicals from Thetford, Walex, Camp Champ, and Odorlos come in liquid, drop-in, and tablet formats.

For fresh water fittings, measure the outside diameter of your existing PEX and identify the connection type before ordering.
