RecPro RV Vacuum Breaker Check Valve | Protect Fresh Water From Pollutants 571-VAC-CHK-A | Made in America

Although this piece is small and simple-looking there are several points that need to be addressed when it comes to proper water safety and installation. First, this should only be used on one fixture at a time. This keeps the pressure in the line predictable and the vacuum breaker able to handle it.
Second, this vacuum breaker is a high-hazard protectant. Because of this, it can be used in a low-hazard application as well.
Third, it should be installed a minimum of 6 inches above the highest point of any item connected to the waste tank where the flusher is installed. This vacuum breaker should also not be under more than 12 hours of continuous water pressure. This could cause the check valve to shut or become stuck.
Fourth, make sure that this vacuum breaker is installed upright. It relies on gravity to properly function and if it is installed in a different position, the valve may not fully open.

FAQ:

Q: How many backflow preventers does an RV have?

A: All RVs have a number of backflow preventers (check valves) in the fresh water plumbing system, some RV’s have as many as 4 backflow preventers. The first one to become familiar with is the one at the city water inlet which connects from the campground water supply into the RV.

Q: Do you need a backflow valve for a water pump?

A: When on city water, you’ll want to keep water from entering the pump and when operating the water pump, you want to keep the water from spewing out the city water inlet. I always recommend carrying a spare backflow check valve just in case.

Q: Do you need a check valve for fresh water in an RV?

A: Install this check valve inside your RV’s fresh water system to prevent backflow and keep nasty contaminants out of your RV’s fresh water plumbing. Durable brass is lead-free, keeping your water safe to drink.

Q: Where is the hot water valve on an RV?

A: Most RV manufacturers now do this at the factory. Likewise with the by-pass kit. It installs at the rear of the water heater between the cold inlet and hot outlet tubes. From the hot outlet on the water heater, simply route the water line to every faucet with a hot water valve.
