This sewer hose kit is designed for standard RV waste outlet and dump station connections. Verify your RV uses a standard 3" sewer outlet and that the dump station inlet style is compatible with the included 4-in-1 adapter. The detachable 4-in-1 adapter is designed for 3" slip and 3", 3-1/2", and 4" NPT threaded sewer connections. Remove the 4-in-1 adapter when needed for compact bumper storage.
Before Starting: Inspect the RV sewer outlet, hose fittings, seals, storage caps, and dump station inlet before connecting. Wear gloves and keep sewer equipment separate from freshwater gear. Basic Use Steps: 1. Select Hose Length: Use one 10-foot section for closer dump inlets or connect both sections for the full 20-foot reach. 2. Connect to RV Outlet: Attach the bayonet fitting securely to the RV’s standard 3" sewer outlet. 3. Attach Dump Elbow: Connect the clear elbow and 4-in-1 adapter to the dump station inlet. 4. Check Hose Slope: Route the hose downhill where possible and avoid sharp bends, kinks, or low spots that can trap waste. 5. Dump Black Tank First: Open the black tank valve first when dumping both tanks. 6. Dump Gray Tank Second: Open the gray tank valve after the black tank to help rinse the hose with gray water. 7. Monitor Flow: Use the clear elbow/extender to see when flow has slowed or stopped. 8. Close Valves: Close all waste valves before disconnecting hose fittings. 9. Rinse and Store: Rinse the hose, drain it fully, install storage caps, and store with sewer equipment only.

Confirm length, storage space, and dump station connection needs before ordering.
To confirm this sewer hose kit is right for your setup, consider the following: • Whether your RV uses a standard 3" sewer outlet • Distance from the RV outlet to the dump station inlet • Whether a 10-foot section, 20-foot setup, or longer extension is needed • Whether the dump station inlet is 3" slip or 3", 3-1/2", or 4" NPT threaded • Whether the hose sections will fit your bumper or storage compartment • Whether you need a separate hose support for proper downhill drainage • Whether your current sewer outlet seals or caps need replacement Why this matters: RV sewer hose kits can share similar names but differ in hose material, fitting style, included adapters, length, storage size, and dump station compatibility.
Match this kit by RV outlet type, required hose length, dump station inlet style, storage space, and included fittings. Do not store sewer equipment with freshwater hoses or drinking water accessories.
If dumping problems continue, inspect the RV sewer outlet, hose slope, bayonet fittings, gaskets, dump station adapter, tank valves, and storage caps before replacing additional sewer components.
This product is for RV black and gray water sewer dumping only. Do not use with drinking water, freshwater hoses, fuel, oil, chemicals, or pressurized potable water systems. Always confirm sewer connections are locked before opening waste valves, wear appropriate protective equipment when handling sewer components, and store sewer equipment separately from freshwater hoses and accessories.
