Review on 💩 Enhance Waste System Efficiency with Valterra Flush King 45 Degree Reverse Flush Valve Attachment for RVs, Campers, and Trailers by Steven Ross

This flush valve is the best, I'll never get in a camper without it again. A few months ago I couldn't close my black water valve and it wouldn't drain. Fortunately, a neighbor had such a flush valve and emptied it immediately. I ordered one the next day. Every time I leave an RV park that I've been at for a while, I flush the black water tank multiple times using this valve. This removes a lot of extra solids from the tank. Trust me if you ever need one of these you will kick yourself for not ordering one. FYI: Don't buy any of these without a valve. Do not pressurize the tank without closing the valve.
