What length RV sewer hose do I need?

Most campsites work fine with a 15 or 20 foot sewer hose, but a 100 foot setup gives you reach for sites where the dump connection sits across the pad or downhill. Carry at least one 10 foot extension so you can match the distance without coiling slack near the inlet. Confirm your bayonet fitting size (the standard is 3 inch) before ordering replacement hoses or extensions.

What parts make up an RV black water system?

The core components are the black tank itself, the termination valve (often called a dump valve), the bayonet fitting, the sewer hose, and the clear elbow at the dump station end. Supporting parts include tank vents, drain pipe, sensor probes, and the flush kit. If you are also prepping for cold weather storage, see our RV winterizing kits to protect the drain lines and valves from freeze damage.

How often should I replace my RV sewer hose?

Plan on replacing a heavy-use sewer hose every one to two seasons, or sooner if you see cracking at the bayonet fitting, pinholes along the corrugations, or a loose seal at the coupling. Hoses stored in direct sun degrade faster. Keeping a spare 10 or 15 foot section in the rig saves a trip when a hose fails mid-trip.

Do you carry sewer accessories beyond hoses?

Yes. The collection covers 186 parts including bayonet caps, 90 degree clear elbows, hose support cradles, gate valves, tank rinsers, drain pipe fittings, and odor control treatments. For related plumbing and exterior gear, browse our RV electronics for tank monitor panels, or our RV patio mats to keep the dump area clean during hookup.
