Features

• RV VACUUM BREAKER CHECK VALVE - Work water pressure range is 8-125 PSI. Connection Type: 1/2 NPT male threads on both the inlet and outlet. Ensure this vacuum breaker is installed upright as it relies on gravity to function properly. Incorrect installation may prevent the valve from fully opening.
• REPLACEMENT FOR RV WATER CHECK VALVE - Ideal for replacing cracked or leaking RV check valves. If your RV vacuum breaker check valve leaks when flushing the black tank, this replacement is the perfect solution.
• FIX FOR LEAKY RV VACUUM BREAKER VALVE - Effective in repairing failed or leaking RV vacuum breaker valves on black tank flush systems. Resolves issues with blocked or faulty black tank flush lines that cause leaks and wet floors in RVs and camper trailers.
• PART OF BLACK TANK FLUSHING SYSTEM - Installs between the freshwater inlet connection and the tank flusher. The vacuum breaker prevents black tank water from mixing with grey water, ensuring the freshwater source remains clean and healthy.
• PREVENTS BACKFLOW AND SIPHONAGE - The black tank anti-siphon valve/vacuum breaker is designed to prevent contents from the black tank from siphoning back into the RV water supply, ensuring the water supply remains free from contamination.
