RV Sewer & Waste
RV waste plumbing runs from the tanks under the floor out to the dump station, and every piece in that run has to seal tight or drain clean. This section covers the whole black-and-gray chain: the gate valves that hold your tanks closed, the holding tanks themselves, the sewer hose that reaches the dump inlet, the supports that keep that hose sloped, the fittings and adapters that tie it all together, and portable tote tanks for when you can't move the rig.

Working through your RV's waste system
Everything on the waste side has to do two jobs: hold sewage in when you want it held, and move it out cleanly when you dump. A failure anywhere in that chain is the kind you notice fast, so it helps to know which category solves which problem before you're standing at the dump station.
- Gate & Dump Valves. The blade valves that seal your black and gray tanks, plus the cables, handles, and linkage kits to operate and rebuild them.
- Holding Tanks. Replacement black, gray, and fresh tanks in ABS, sized by gallon and drain position, most with level sensors pre-installed.
- Sewer Hoses & Kits. The hose from your rig to the dump inlet — standard 10- and 20-foot lengths, collapsible extensions, end caps, and complete kits.
- Sewer Hose Supports. Slinky-style troughs and telescoping cradles that hold the hose on a downhill slope so it actually drains.
- Tank Fittings. The elbows, wyes, adapters, and flush fittings that connect tanks, valves, and hoses — including clear elbows for the dump station.
- Tote Tanks. Wheeled portable tanks that let you dump without moving the RV when you're parked long-term without a sewer hookup.
If you're chasing a specific problem — a valve that won't seal, a cracked tank, a hose that keeps clogging — start in the matching category. For odor and buildup, the tank care and chemicals section next door handles treatments and cleaning.
