Valterra Reverse RV Flush Valve

The Valterra F02-4350 Reverse RV Flush Valve saved us from a major problem.

Once when we opened the black water tank valve, nothing happened because we had a clog. More details can be found at our blog post We Met The Enema, And It Was Us.

We now use it every time we empty the black tank, doing about 4 flushes of fresh water to clean out the tank.

We never have problems anymore with clogs.
