RV Sewer Hoses

What should come in an RV sewer hose kit?

A complete RV sewer hose kit has a 3" diameter hose, a bayonet fitting that locks onto your RV's 3" waste outlet, and a sewer adapter or elbow that seals into the campground drain inlet. Many kits also include end caps for odor-free storage. Before ordering, read the listing to see whether a clear elbow, extra coupler, or storage caps are included or sold separately. Some kits ship with the hose and fittings only.

How do I choose the best RV sewer hose?

Judge an RV sewer hose by its specs, not its packaging. Wall thickness, listed in mil, is the main factor: a thicker wall resists punctures, abrasion on gravel pads, and UV cracking better than a thin hose. A steel wire helix keeps the hose from crushing or kinking. Pre-attached, locking bayonet fittings reduce the chance of a leak at the outlet. Full-timers and owners who dump often get the longest service life from a heavier-wall hose. Occasional campers can often use a lighter hose that stores more compactly.

What length RV sewer hose do I need?

A 10' to 15' RV hose covers most pull-through sites. A 20' hose or longer gives you room on back-in sites where the drain sits far from your outlet. Short hoses such as the Prest-O-Fit 1-0062 5' Ultimate sewer hose work for tight dump stations or as an extension. You can join two hoses with a coupler, but each added connection is one more possible leak point. Keep a steady downhill slope from the RV to the inlet so the tank drains completely.

Will a sewer hose fit my RV and the campground drain?

Nearly all RVs use a standard 3" bayonet waste outlet, so a standard 3" RV sewer hose fitting will connect to your black and gray tank valve. Campground inlets vary more. They can be 3", 3.5", or 4" threaded, or an open pipe, so a sewer adapter with stepped threads or a rubber seal covers the most sites. At a full-hookup site, level the RV first with Lynx RV leveling blocks, then run the sewer hose so it keeps a consistent downhill slope to the inlet.

What else do I need for a full-hookup campsite connection?

Along with your sewer hose kit, plan for your shore power connection. Protect your electrical system with one of our Southwire Surge Guard RV surge protectors. Carry RV detachable adapters for pedestals that do not match your cord. If you are unsure which sewer hose or fitting matches your setup, text or call 817-984-1852 with your RV make and model.
