Valterra Flushing Hose for RV

Tough, and built for the job — my go-to hose for safe, effective RV black tank and sewer system flushing.


Overview

The Valterra Flushing Hose is a heavy-duty, non-potable water hose specifically designed for flushing and cleaning your RV’s black and gray water systems. Unlike your drinking water hose, this dark-colored flush hose is dedicated to waste-related tasks — preventing contamination between your freshwater and sanitation systems.

Ideal for use with black tank flush connections or rinsing sewer hoses, this hose is built to withstand high pressure and outdoor use without kinking or leaking. It’s an essential accessory for any RVer who values safe and sanitary waste management practices.


Key Features

  • 25-foot reinforced hose designed for non-potable water use
  • Distinct color for easy identification and safety
  • Standard ¾” GHT fittings for compatibility with most RV black tank flush ports
  • Kink-resistant construction ensures steady water flow during flushing
  • Durable, UV-stabilized materials for long service life outdoors

RV Use Cases

  • Connects to RV black tank flush inlet for thorough internal cleaning
  • Rinses sewer hoses, elbows, and fittings after tank dumping
  • Ideal for cleaning out portable waste totes or external sewer accessories
  • Provides safe separation from potable water supplies

Common User Feedback

Pros:

  • Strong, flexible, and resistant to leaks or bursting
  • Easy to identify — prevents accidental mixing with drinking water hoses
  • Excellent value for its durability and quality

Cons:

  • Not rated for drinking water (non-potable only)

Best Practices

  1. Label clearly or store separately from your freshwater hose to prevent cross-contamination.
  2. Use only for black tank flush or sewer hose cleaning.
  3. Inspect fittings regularly for cracks, leaks, or mineral buildup.
  4. Flush thoroughly after use and allow to dry before storage.
  5. Store capped or in a sealed bin to keep clean and odor-free between uses.
