RV Sewer & Waste

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.
