RV Sewer Hoses

What length RV sewer hose do I need?

Most RV owners carry a 20-foot hose, which covers the majority of campground dump station distances. If you frequent older parks or sites with offset connections, a 20-foot primary hose plus a 5-foot or 10-foot extension gives you flexibility without dragging excess hose. Measure from your black tank outlet to a typical campsite sewer inlet before ordering. Pair your hose with the right RV winterizing kits when temperatures drop to protect the whole drain line.

What is included in a complete RV sewer hose kit?

A complete kit typically includes the hose itself (15 or 20 feet), a clear elbow fitting with bayonet lugs for the dump station, a bayonet adapter for the RV outlet, and storage caps on both ends. Better kits add a 4-in-1 sewer adapter to fit 3-inch and 3.5-inch threaded or slip-fit inlets. The Prest-O-Fit Ultimate kits and similar systems in this collection ship with all four fittings, so you are not chasing parts at the dump station.

How do I store an RV sewer hose between trips?

Rinse the hose thoroughly with fresh water, drain it fully, and cap both ends before stowing it in a dedicated sewer hose storage tube or your rear bumper compartment. Keeping it isolated from fresh water hoses and drinking water gear is non-negotiable. For freshwater connections and drinking hoses, see our RV accessories options to keep the two systems clearly separated.

Are these sewer hoses compatible with standard RV waste outlets?

Yes. Every hose and kit in this collection uses the industry-standard 3-inch bayonet fitting that mates with the waste outlet on virtually all towable and motorized RVs built in the last 30 years. Dump station connections vary more, which is why the included clear elbow with a 4-in-1 adapter handles 3-inch and 3.5-inch threaded, slip, and rubber-donut inlets. Confirm your RV outlet style if your rig is older than 1990 or has been modified.

What is the difference between vinyl and polyolefin RV sewer hoses?

Vinyl hoses are the budget standard and work fine for occasional weekend use, but they stiffen in cold weather and can crack after a season or two of UV exposure. Polyolefin hoses, like the Prest-O-Fit Ultimate and Camco RhinoFLEX lines, hold their shape, resist crushing, and last several years of full-time use. Full-timers and snowbirds should buy polyolefin once rather than replacing vinyl every season.
