This model emphasizes backflow prevention with a built-in vacuum breaker, safeguarding freshwater supplies. A clear 45-degree elbow enhances visibility to verify rinsing progress and ensures thorough cleaning of residue inside the black tank. The setup is designed to integrate smoothly between your faucet and camper water hose for reliable performance.
Camco RV Holding Tank Swivel Stik Rinser
The Swivel Stik Rinser delivers powerful rotary cleaning action with a 34-inch flexible reach to access remote areas of the waste tank. It includes a 1/4-turn shutoff valve and an ergonomic handle for precise water control, enabling targeted cleaning in tight spaces and along the tank walls to help prevent odors and buildup.

The Dual Flush Pro is designed to rinse both waste tanks and sewer hoses. It accepts a 3-inch gate valve for universal compatibility, making it suitable for RVs without built-in black tank flush systems. Its reverse flush valve enables backflushing to dislodge stubborn clogs and clear debris from plumbing lines, improving overall sanitation and tank readings.

This solution is intended to remove buildup from tank walls and pipes, aiding in odor control and ensuring more accurate sensor readings after treatment.
Buying Guide
Key purchase considerations for RV black tank flush systems include compatibility, ease of installation, and the level of maintenance required. Consider these perspectives to select the best option for your RV setup:
- Tank size and plumbing compatibility: Ensure the device supports your RV’s tank size and drain outlets. A 3-inch gate valve is commonly compatible with many rigs, but confirm fitment before purchasing.
- Flow control and shutoff: Look for a model with precise flow control (such as a 1/4-turn valve) to prevent splashing and to optimize cleaning in tight spaces.
- Backflow prevention: A built-in vacuum breaker protects your freshwater supply from potential backflow. This is especially important when using external water hoses for rinsing.
- Reach and maneuverability: Swivel or flexible devices extend your cleaning reach to hard-to-access areas, reducing dead zones in the tank walls.
- Visibility and diagnostics: Clear elbows or see-through components help confirm when rinsing is complete and the tank is clean.
- Odor control and tank conditioning: Enzymatic treatments and cleaners can supplement physical rinsing by breaking down waste and neutralizing odors, while ensuring sensors remain accurate.
- Maintenance and safety: Choose products designed to avoid damage to seals or valves. Avoid harsh chemicals that could compromise plumbing materials.
- Convenience vs. cost: Consider whether you prefer an all-in-one rinsing system or modular components that you can upgrade over time.
When selecting a system, assess your typical RV usage, whether you frequently travel with limited access to dump stations, and how often you perform tank maintenance. A combination of a high-quality rinser (for routine cleaning), a backflow-protected valve (for safety), and occasional enzymatic treatment can provide a comprehensive approach to keeping black tanks odor-free and functioning smoothly.
