Camco Dual Flush Pro RV Holding Tank Rinser | 3" Gate Valve & Reverse Flush

Camco's Dual Flush Pro attaches to your RV's 3-inch drain outlet and gives you a reverse-flush valve that backfills your holding tank and sewer hose with water under pressure, helping clear clogs and rinse out solids that a straight dump alone won't touch. It's especially useful on rigs without a factory black tank flush system.

• Fits standard 3" RV gate valve drain outlets
• Reverse flush valve backfills and flushes tank and sewer hose with pressurized water
• Two-position gate valve: closed for tank flushing, open to direct water into the sewer hose
• Clear adapter lets you see when waste water is running clean
• Durable gate valve and polymer adapter construction
• Connects to your RV sewer hose and a garden hose for the backflush

A practical add-on for keeping the black tank and hose cleaner between dump station visits, especially on RVs that don't have a built-in flush system.
