Camco Dual Flush Pro RV Holding Tank Rinser – 3" Gate Valve, Reverse-Flush + Clear Adapter for Black/Grey Tanks

If you own a motorhome, travel trailer, fifth wheel, or camper without a factory black tank flush, this Camco Dual Flush Pro accessory is built to simplify waste system maintenance. It combines a 3" gate valve sized to fit most RV drain outlets, a reverse-flush function to dislodge debris, and a clear adapter so you can see when your tanks and hose run clean. The unit is made from durable materials to survive heavy use at campgrounds and on the road, and its design focuses on easy connection, reliable flow control, and thorough rinsing.

How does the Dual Flush Pro make tank emptying easier?

The Dual Flush Pro lets you control whether wastewater is routed out through your sewer hose or used to rinse the hose and tank internally. With a simple gate valve action you can close the valve to isolate the hose while forcing rinse water into the tank, or open it to direct flow through the sewer hose for hose cleaning. This flexibility reduces manual scrubbing and repeat drain cycles.

• 3" gate valve fits most RV drain ports for straightforward installs.
• Two valve positions: closed for internal tank rinsing, open for hose flushing.
• Clear adapter gives a visual cue when waste water runs clear.
• Reverse flush breaks up settled solids and minimizes odors.

Can it clear clogs and improve tank hygiene?

The built-in reverse flush valve forces water back into the tank and hose to loosen trapped solids that can cause clogs and smells. That higher-pressure backfill action targets problem spots, then you can drain the dislodged debris into the sewer line. Regular use helps maintain cleaner plumbing and reduces the need for harsh chemicals or intensive manual cleaning.

• Reverse flush dislodges debris adhering to tank walls or fittings.
• Use with fresh water to flush residues and minimize odor buildup.
• Reduces reliance on aggressive chemical cleaners when used routinely.
• Clear adapter confirms when rinsing is complete and water runs clear.

How do I install and operate it on my camper or motorhome?

Installation is straightforward: connect the 3" gate valve to your RV drain outlet, attach your sewer hose to the rinser’s outlet, and hook up your grey water hose to the backflow stopper as needed. Turn water on, set the gate valve to the desired position (closed for tank rinse, open for hose flush), and monitor the clear adapter to know when the system is clean. The unit’s durable construction allows repeated seasonal use without frequent replacement.

• Attach to standard 3" RV drain outlets—no specialty tools needed.
• Connect sewer hose to rinser outlet with common RV fittings.
• Use gate valve positions to choose rinse or flush function quickly.
• Inspect through the clear adapter to verify cleanliness visually.

What materials and durability can I expect from the Dual Flush Pro?

Camco built the Dual Flush Pro from sturdy polymer and a robust gate valve mechanism designed to withstand routine campsite use. The clear adapter is made to resist cracking so you can reliably check flow without disassembling the system. The overall construction keeps leaks, breaks, and premature wear to a minimum when used as recommended.

• Unbreakable polymer clear adapter for reliable visual checks.
• Sturdy gate valve engineered for frequent open/close cycles.
• Materials chosen to resist corrosion and campsite wear.
• Designed for compatibility with typical RV sewer hoses and fittings.

Who this is for: The Camco Dual Flush Pro is aimed at RV owners who want a practical, no-fuss solution to keep black and grey tanks and sewer hoses cleaner between professional service visits. It’s especially useful for owners of rigs without factory tank-flush systems, those who experience recurring buildup or odors, and campers who prefer a visual confirmation of a successful rinse. If you value easy connections, effective reverse flushing, and a durable accessory that simplifies on-the-road sanitation, this rinser is a smart addition to your campsite toolkit.
