Stubborn waste tank clogs yield to this reverse flush valve. Attach it to your fill inlet, then reverse your freshwater line to build pressure that blasts through blockages from inside the tank. The built-in backflow preventer protects your water supply, and the tool works at any tank angle—even horizontal plumbing sections that gravity can’t clear.

• Removes tank clogs via reverse flushing
