Valterra’s Flush King Reverse RV Flush Valve lets you reverse flush your black or gray water holding tank from outside the RV. It refills, rinses, and cleans out pipes regardless of the bend or height in the plumbing. It helps remove clogs from drain pipes, and helps clean sensor probes to maintain accurate level monitoring. The anti-siphon valve helps protect the fresh water supply from possible contamination.
The Flush King attaches quickly and easy. Simply connect the Flush King to your RV Drain Outlet and then connect your RV sewer hose to the Flush King. Connect your gray water hose to the to the backflow preventer on the Flush King. Turn on the water to start flushing. The clear barrel lets you see when the tank is clean. It’s just as easy to disconnect the Flush King and store it for next time.
