Sewer Hoses & Kits

Picking a sewer hose that lasts

Thin-wall hose is where most complaints start — it punctures on the first sharp rock and splits at the fittings after a season in the sun. What you pay for in a better one is wall thickness, reinforcement, and fittings that lock instead of pop. Match the length to how far your outlet sits from a typical dump inlet, and keep an extension on hand for the sites where it's farther than you'd like.

• Wall construction. Heavier is better here. The Valterra EZ Flush triple-wrap and Silverback 24-mil polypropylene hoses resist crushing and punctures far better than thin-wall hose, and they hold their shape when you're steering flow downhill.
• Length and extensions. A 20-foot hose (like the EZ Flush bronze) covers most sites; a 10-foot handles close hookups without excess to store. A 5-foot collapsible extension bridges the odd long reach without carrying a second full hose.
• Fittings and end caps. Bayonet fittings twist-lock to your rig and to adapters; the Thetford Titan uses a bayonet connection with a durable TPE hose. Rubber press-fit end caps like the Titan set keep the ends sealed and clean in storage.
• Complete kits. A kit like the Camco Superkit gives you the hose, connectors, and storage caps in one box, which is the simplest way to start from scratch or replace a whole worn setup.

A hose only drains fully if it runs downhill the whole way, so pair it with a sewer hose support to hold the slope. At the dump end, a clear elbow and the right adapter from tank fittings let you see when the water runs clean and seal into the ground inlet.
