Measure the route from the RV outlet to the dump connection, then compare hose length, end fittings, adapter, caps and storage needs. Check that the kit's RV-side fitting and dump-station adapter match your connections; features listed for Thetford Titan kits apply to those products, not every sewer hose.
An RV sewer hose kit is a collection of parts that must reach the dump connection and fit at both ends. Check your outlet, likely route, adapter and storage space before comparing a short kit with a longer one.
Compare the kit contents
| Part | What to check |
|---|---|
| Hose | Length, diameter, storage space and whether the maker supports extensions |
| RV-side fitting | Connection type and fit to the RV outlet |
| Dump-station adapter | Port compatibility and any stated range of outlet types |
| End caps and seals | Whether caps and replacement seals are included and match the hose |
| Storage or support | Where the hose will be carried and whether a separate support suits the route |
As one specific example, Thetford’s Titan 15-foot kit lists a universal bayonet fitting, a 5-in-1 adapter with handle, two end caps and two EPDM seals. Its Revolve adapter page says that adapter fits five common sewer port connections. Check the exact product page because kit contents differ by length and model.
Measure the route
Measure from the RV outlet to the dump-station connection along the intended hose path, including the height and turns around the site. Choose enough length to reach without tugging on the outlet fitting. If using an extension, verify that the connection type and seal match the hose system.
Keep fresh-water gear separate
Store sewer equipment separately from the drinking-water hose and fittings. The RV drinking-water hose and pressure regulator guide covers potable-water hookups; the RV winterizing checklist covers model-specific plumbing preparation for cold storage.

Common questions
What length RV sewer hose should I buy?
Measure the path from the RV outlet to the dump connection at the sites you use, and allow enough reach for the route without pulling on the fittings. Add a compatible extension only if the hose maker permits it.
What comes in an RV sewer hose kit?
Contents vary. Thetford's Titan 15-foot kit lists one 15-foot hose, a 5-in-1 adapter with handle, two end caps and two EPDM seals.
Do RV sewer hose kits fit every dump station?
No single adapter should be assumed to fit every outlet. Check the kit's adapter against your RV outlet and the dump-station port; Thetford says its Revolve adapter fits five common port connections.
Can RV sewer hoses be connected together?
Some makers offer compatible extension sections. Check the hose system's fitting and seal compatibility before combining sections.
