Lippert 20 Ft Extended Made in USA Lippert 376294 Waste Master Replacement Sewer Hose -- 20 Ft

Purpose-built for the Waste Master sewer management system, this 20-foot replacement hose gives you the full reach of the original with a smooth interior bore, a clear-view end fitting, and a durable outer coil that resists punctures, abrasion, and UV degradation. When your original hose wears out, this is the direct replacement -- no adapters, no improvising.

The Right Hose for Your Waste Master System

The Waste Master system is designed around a specific hose geometry and fitting interface. Generic sewer hoses compromise the system's sealed, drip-free operation. Lippert part 376294 restores full factory functionality -- same outside helical coil construction, same 3-inch interior diameter, and the same clear-view elbow fitting that lets you watch the flow and know exactly when your black and grey tanks have finished draining.

At 20 feet extended and just 5.5 feet compressed, this hose stores compactly in the Waste Master's integrated storage tube and deploys to reach most campground sewer connections without an extension. The exterior helical coil keeps the hose at whatever length you need rather than collapsing back toward the RV mid-dump.

Clear-View End Fitting

Translucent elbow lets you monitor flow so you can close the valve as soon as the tank is empty -- no guessing, no early shutoff.

Outside Helical Coil

Coil sits on the outside of the hose wall, leaving the interior smooth and unobstructed for maximum flow and easy flushing.

Self-Supporting Length

Advanced coil design holds the hose extended at the length you set -- no drooping into puddles, no accordion collapse during the dump.

UV and Puncture Resistant

Formulated to handle repeated outdoor use without cracking, fading, or becoming brittle -- even after seasons of sun exposure and rough ground.

Why Outside Helical Coil Matters

Traditional corrugated sewer hoses have their ribs on the inside of the hose wall. Waste accumulates in those internal grooves, creates odor, and makes the hose difficult to flush clean. The Waste Master hose routes the support coil on the outside, so the flow path is a smooth 3-inch bore from end to end. Solids clear cleanly, and a simple rinse leaves the interior ready for the next use.

Smooth Interior = Better Flow and Easier Cleanup
No internal ribs means no debris traps. Waste moves freely from tank to dump station, and a quick backflush leaves the hose clean.

Fitment and Compatibility

This hose is designed exclusively for the Lippert Waste Master sewer management system. It is not a universal sewer hose and is not intended for use with standard bayonet or Rhino-style termination adapters without the Waste Master nozzle assembly.

Nozzle Not Included
This listing covers the replacement hose only. The Waste Master sewer nozzle (Lippert part 349521) is sold separately. If your nozzle is damaged or missing, order it alongside this hose.

Storage and Deployment

Compressed length of 5.5 feet is sized to fit inside the Waste Master's built-in storage tube on your RV's bumper or undercarriage mount. When you arrive at a site, pull the hose out, route it to the cleanout, and the coil holds it in place. No hose support stands required for most connections at or below the RV's sewer outlet height.

Compressed for Easy Storage
5.5 ft compressed fits the Waste Master storage tube. 20 ft extended handles most campground pad layouts without needing an extension section.

Durability and Construction

The hose body is UV-stabilized and formulated to resist the abrasion of pavement, gravel, and concrete at campgrounds. The outer coil is bonded to the hose wall rather than simply wrapped, maintaining its shape and protective function over repeated compress-and-extend cycles. Weight of 4.5 lbs keeps the total Waste Master system manageable to handle solo.

Maintenance Tip
After each dump, run fresh water through the hose before compressing it for storage. The smooth interior clears quickly. Avoid dragging the hose across sharp gravel at an angle -- the outer coil is tough, but repeated point abrasion on rough surfaces will wear any hose over time.

Important Information
  • This hose is a Waste Master system-specific replacement and is not compatible with standard RV sewer hose fittings or bayonet termination adapters.
  • The Waste Master nozzle (Lippert part 349521) is NOT included. A complete dump setup requires both the hose and the nozzle.
  • Do not use this hose for freshwater, potable water, or any application other than RV black/grey waste drainage.
  • Always inspect the hose and fittings for cracks, splits, or loose connections before each use to prevent spills.
  • Store compressed inside the Waste Master storage tube when not in use to protect the hose from UV and physical damage.
  • Weight: 4.5 lbs. Handle and route the hose so it is supported near both ends to avoid undue stress on the end fittings.
