Adds 10 feet of reach to your existing RV sewer hose when the dump station inlet is too far away. Heavy-duty 23-mil UV-stabilized polypropylene holds its shape and drains cleanly without sagging. Patented rotating swivel fittings prevent twisting. Stays flexible to -20°F. Collapses from 10 feet to 39 inches for compact storage.
Every RV owner eventually encounters a dump station where the sewer inlet is just too far from where the RV is parked — or a campsite where the hookup requires more hose than you brought. The Dominator 10-Foot Extension solves this without replacing your entire sewer hose setup, adding 10 feet of heavy-duty reach by connecting between your RV's waste valve and your existing hose.
The Dominator uses 23-mil polypropylene — one of the thicker wall constructions available in RV sewer hoses — which gives it the rigidity to hold its position and maintain a proper downhill drain angle rather than sagging and pooling waste mid-run. UV stabilization protects the material from sun damage and keeps it from becoming brittle over seasons of outdoor use, and cold-weather flexibility down to -20°F means it won't crack or stiffen up on late-season camping trips. The patented rotating swivel fittings on both ends rotate independently, which eliminates the frustrating twisting and kinking that plagues non-swivel hoses when you're working around the RV's rear bumper. When done, the hose collapses from its full 10-foot length down to just 39 inches for storage in the RV's bumper tube or under-bay compartment.
Both ends rotate independently — prevents the hose from twisting and pulling away from the valve or sewer connection during use
Thick 23-mil polypropylene wall holds its shape and maintains drain angle — won't sag and pool waste mid-hose like thinner alternatives
Full 10 feet of reach when deployed, collapses to just 39 inches — fits in standard RV bumper storage tubes
Stays pliable in cold weather down to -20°F — won't stiffen or crack on late-season or cold-climate camping trips
The D04-0200 is designed to add length to an existing sewer hose setup, not replace it. Here's how the connection typically works: Configuration 1 — Extension from RV valve: Attach the bayonet fitting on the D04-0200 directly to your RV's 3" waste valve outlet, then connect your existing sewer hose from the extension's lug fitting to the dump station inlet. Adds 10 feet of reach closest to the RV. Configuration 2 — Extension at the dump end: Connect your existing sewer hose from the RV's waste valve as normal, then attach the D04-0200 extension at the far end between your hose's end and the dump station inlet. Useful when extra reach is needed at the sewer end. Fitting compatibility: The D04-0200 uses standard 3" bayonet and lug fittings compatible with most major RV sewer hose brands including Camco, Valterra's own Dominator and Silverback lines, and others. If your existing hose uses bayonet fittings on both ends, you may need a bayonet-to-bayonet adapter. Always dump the black tank first, then the gray water tank — the gray water helps flush residual waste through the hose.
At the Dump Station: 1. Put on gloves — always wear disposable gloves when handling sewer hose connections 2. Connect the extension: Attach the D04-0200's bayonet fitting to your RV's waste valve, or connect inline with your existing hose 3. Connect your hose to the dump inlet: Run the extension and/or existing hose to the dump station sewer inlet and secure 4. Position for drainage: The Dominator's 23-mil poly holds its shape — adjust to maintain a consistent downhill angle from the RV to the dump inlet 5. Open black tank first: Always dump the black water tank before the gray — gray water flushes residual waste through the hose 6. Rinse, disconnect, collapse: Rinse hose if possible, disconnect from dump inlet, collapse to ~39" for storage Never leave tank valves open continuously while connected to sewer — open only when dumping to allow full tank pressure to flush waste cleanly.
