Break up tank clogs and restore flow with this reverse-flush valve designed for serious tank maintenance. It connects to your dump-station freshwater line and pumps pressurized water backward through your sewer system to dislodge stubborn waste deposits. An internal backflow preventer stops contamination, and a removable anti-siphon valve prevents cross-contamination. Use it annually to keep your tanks and hoses flowing freely.
