  • Compatibility: 571-VAC-CHK-A RV Vacuum breaker check valve Compatible with Montana Mountaineer, Grand Design Reflection, Newmar, Coachman Leprechaun, Keystone: Passport/Outback, Forest River and other RV blackwater cleaning systems. Check and make sure the breaker your pipe is adapted to has a nominal diameter of 1/2 inch.
  • Function: RV vacuum breaker check valve ensures the stability of the vacuum system, prevents the backflow of water from the black water tank back into the domestic water system you use for flushing water, prevents fresh water resources, and keeps the water source clean and sanitary.
  • Premium Quality: 571-VAC-CHK-A RV vacuum breaker check valve is constructed of durable brass material that withstands high water pressure to ensure long-lasting performance and water safety, with better sealing and quieter operation, as well as sensitively sensing the water pressure.
  • Easy Installation: With 1/2" NPT male threads on both the inlet and outlet, this vacuum breaker check valve fit for 1/2" pex pipe. Remove the old check valve and verify the direction of installation: fresh water should flow in the "FLOW" direction as indicated by the arrow on the valve body, then connect the check valve to the pipe. NOTE: Installation should be approximately 6 inches above the flusher and be sure to install vertically.
  • Wide Application: Brass RV vacuum breaker check valve can solve all kinds of RV, camper, travel trailer black water tank check valve leakage, clogging, malfunctioning and other problems. If your RV check valve leaks when flushing the black water tank, or the black water tank flushing line system is clogged/ failed and wetting the RV camping trailer floor, you can just replace it.
