What Is the Camco Dual Flush Pro?
The Camco Dual Flush Pro 39062 is an RV holding tank rinser and sewer hose rinsing valve. It attaches to a standard 3-inch RV drain outlet, then lets you use an external water hose to reverse flush the tank or rinse the sewer hose. Camco designed it for campers, travel trailers, fifth wheels, and motorhomes that need extra help with waste tank cleaning.
The main feature is the two-position gate valve. In the closed position, it helps send rinse water back toward the grey or black tank. In the open position, it directs water through the sewer hose so you can rinse residue from the hose before storage.
The clear adapter gives you a visible look at the water flow while you rinse. That matters because you can stop when the water runs clearer instead of guessing from the outside. At 9.75 x 4.5 x 8.75 inches and 1.53 lb, it stays portable enough for most RV storage compartments.
Key Takeaways
- The Camco Dual Flush Pro 39062 uses a 3-inch RV gate valve to fit most standard camper, travel trailer, motorhome, and fifth wheel drain outlets.
- The reverse flush valve helps backfill and rinse black tanks, grey tanks, plumbing lines, and sewer hoses with external water pressure.
- The clear adapter lets you watch the rinse water, so you can tell when the tank or hose looks cleaner.
- The two-position valve lets you choose between tank flushing and sewer hose rinsing from one compact RV sanitation tool.
- The 1.53 lb plastic body stores easily, but you still need a separate water hose and enough space around your RV drain outlet.
Who It’s For and Who Should Skip It
Who It’s For
- RV owners with a standard 3-inch drain outlet who want a portable tank rinsing tool.
- Campers whose RV does not include a built-in black tank flush system.
- Travel trailer and fifth wheel owners who want to rinse the sewer hose before packing it away.
Who Should Skip It
- You should skip it if your RV uses a non-standard drain fitting that cannot accept a 3-inch valve connection.
- You should skip it if you do not have access to a safe external water source at dump stations or campsites.
- You should consider a built-in tank flush system if you want a permanent setup with fewer separate parts to store.
Why Every RVer Needs the Camco Dual Flush Pro
The Camco Dual Flush Pro solves a real RV maintenance problem: waste tanks and sewer hoses do not always rinse clean after a basic dump. A normal gravity drain can leave tissue, residue, and small debris inside the tank or hose. This model gives you a controlled way to push water back through the system and loosen that buildup.
For RV owners without a built-in tank flush, the Camco Dual Flush Pro adds a simple reverse-rinse option at the drain outlet.
The product uses a universal 3-inch gate valve, a clear adapter, and a reverse flush valve. That setup works with most standard RV drain outlets on campers, travel trailers, motorhomes, and fifth wheels. The clear section also helps you monitor the rinse water during cleanup.
You get the most benefit if you camp often, use full-hookup sites, or travel with family. More tank use usually means more need for regular rinsing. The Camco Dual Flush Pro can also help if your tank sensors give unreliable readings because residue stays on the tank walls.
Before you buy, check your drain outlet position and storage space. The unit measures 9.75 inches long, so tight dump valve areas may need extra clearance. You also need a water hose connection because the reverse flush action depends on outside water pressure.
How the Dual Flush Pro Works and What It Fits
The Dual Flush Pro attaches between your RV drain outlet and your sewer hose. You connect the 3-inch gate valve side to your RV, attach the sewer hose to the opposite end, and connect a water hose to the rinse inlet. Once connected, the valve lets you control where the rinse water goes.
The closed valve position helps send water back toward the grey or black tank. That reverse flow can loosen debris inside the tank and plumbing line. The open valve position lets water move into the sewer hose, which helps rinse the hose after draining.
The fit works best on standard 3-inch RV drain outlets. Camco lists the Dual Flush Pro for campers, travel trailers, motorhomes, and fifth wheels. You should measure your drain outlet and check for enough hand clearance before you depend on it for a trip.
The product does not replace safe dumping habits. You still need to use a proper sewer hose, connect securely, and avoid overfilling the tank during backflushing. Stay near the valve while rinsing so you can control flow and prevent messy mistakes.
Durability, Ease of Use, and Real-World Performance
Durability matters because RV sewer accessories face water pressure, vibration, storage bins, and repeated campsite use. The Camco Dual Flush Pro uses plastic construction with a clear adapter and a robust gate valve assembly. The product details also list CSA and ULC specifications.
The unit weighs 1.53 lb, so you can handle it easily while wearing gloves. The 9.75-inch length gives you enough body to control the valve, but it may feel bulky in a cramped wet bay. You should test the fit at home before you need it at a dump station.
Ease of use stays simple once you understand the valve positions. You connect the rinser to the RV drain outlet, attach your sewer hose, connect the water hose, then open or close the gate valve based on the rinse job. The clear adapter gives you visual feedback while you flush.
For best results, use a dedicated non-drinking-water hose for tank rinsing. You should also keep any backflow preventer or anti-siphon connection in place when using a pressurized water source. That habit helps protect your fresh water setup from contamination risk.
Design and Build
The Camco Dual Flush Pro uses a compact plastic body with a clear viewing section. The clear adapter helps you see flow color and debris movement during rinsing. That design makes the tool more useful than an opaque connector because you can monitor the rinse instead of guessing.
The 3-inch gate valve gives the unit its main control point. You can hold rinse water back for tank flushing or open the path for sewer hose rinsing. This simple mechanical design also means you do not need batteries, apps, or electrical power.
Reverse Flushing Performance
The reverse flush valve sends water back toward the holding tank and sewer line. This helps break up loose residue and minor clogs in plumbing lines. It works best when your RV layout gives the water a direct shot toward the holding tank.
You should not treat this as a cure for every tank blockage. Heavy buildup, poor tank slope, or a hard obstruction may need a deeper cleaning tool. For routine flushing after dumping, the Camco Dual Flush Pro gives you a practical way to improve rinse quality.
Compatibility and Fit
Camco lists the Dual Flush Pro for most drain outlets on campers, travel trailers, motorhomes, and fifth wheels. The key requirement is the standard 3-inch RV drain connection. If your setup uses an unusual adapter or custom drain layout, you may need a separate fitting.
Clearance matters as much as connection size. The rinser measures 9.75 x 4.5 x 8.75 inches, so low drain outlets or tight bumper areas can make installation awkward. Check your drain bay before a trip so you do not find a fit problem at the dump station.
Cleaning and Storage
After each use, rinse the Camco Dual Flush Pro with clean water and let it drain. The clear adapter helps you confirm that visible residue has left the unit. Once dry, store it in a sealed or ventilated bin away from drinking water hoses.
You should inspect the seals before longer trips. Sewer fittings can leak when gaskets wear, dry out, or twist during connection. Carrying a spare gasket can save you from a messy problem at a campground dump station.
How It Performs in Real Use
At a Full-Hookup Campsite
At a full-hookup site, the Camco Dual Flush Pro gives you more control than a basic drain-and-go routine. You can dump the black tank, send rinse water back through the valve, then watch the clear adapter as water quality improves. This helps you leave the tank cleaner before travel day.
At a Public Dump Station
At a dump station, the setup can work well if you have access to a rinse water source and enough time. The 3-inch connection and two-position valve keep the process simple, but you still need to manage the hose connection carefully. Use a dedicated rinse hose, not your fresh drinking water hose.
For Sewer Hose Cleanup
The open valve position helps send water through your sewer hose after the tank drains. This can reduce leftover residue before you disconnect and store the hose. The clear adapter helps you see when the flow looks cleaner.
Pros and Cons
Pros
- 3-inch RV gate valve fits most standard camper, travel trailer, motorhome, and fifth wheel drain outlets.
- Clear adapter lets you watch rinse water during tank and sewer hose cleaning.
- Two-position valve supports both tank backflushing and sewer hose rinsing.
- 1.53 lb weight makes it easy to handle and store in an RV compartment.
- No-tools setup keeps the process simple at campsites and dump stations.
Cons
- You need a separate external water hose and a safe rinse water source.
- The 9.75-inch body may not fit easily in very tight drain outlet spaces.
- Non-standard RV drain fittings may need extra adapters before use.
Is It Worth the Price?
The Camco Dual Flush Pro offers strong value for the price if you want a portable tank rinsing tool instead of a permanent flush system. You get a 3-inch gate valve, clear adapter, reverse flush function, and sewer hose rinse option in one compact accessory. That mix makes sense for many weekend RVers and seasonal campers.
You get the most value if your RV does not already have a built-in black tank flush. The tool can also help if you often deal with slow draining, dirty sewer hoses, or unreliable tank sensor readings. You should spend more on a different solution only if you need a permanent system or your RV layout blocks this style of external rinser.
How It Compares to Alternatives
The Valterra Hydroflush is a common alternative if you want a clear reverse flush elbow in a 45-degree or 90-degree style. It may fit better in some tight drain layouts, but it does not give every buyer the same straight-line valve control as the Camco Dual Flush Pro.
The Camco Rhino Blaster is another option for RV owners who want a tank rinser with a strong flushing design. The Camco Dual Flush Pro remains the better pick if you want a simple 3-inch gate valve setup with a clear adapter and two-position control in a compact tool.
Frequently Asked Questions
Can the Camco Dual Flush Pro connect to non-standard 3-inch drain fittings?
It works best with standard 3-inch RV drain outlets. If your RV uses a custom drain fitting or unusual adapter, you may need another connector before the Dual Flush Pro fits securely.
Does the Camco Dual Flush Pro need a separate water source?
Yes. The reverse flush action needs an external pressurized water source and a rinse hose. Use a dedicated hose for waste tank rinsing and keep it separate from your drinking water hose.
Does the Camco Dual Flush Pro work with portable cassette toilets?
It is not the right tool for most portable cassette toilets. The product targets RV waste systems with standard 3-inch drain outlets, such as campers, travel trailers, fifth wheels, and motorhomes.
Are replacement adapters or parts available for the Camco Dual Flush Pro?
Camco sewer fittings and related replacement parts are widely sold by RV retailers. Before ordering parts, match the model number 39062 and check the fitting size so you do not buy the wrong gasket or adapter.
Can you store the Camco Dual Flush Pro inside the RV?
Yes, you can store it inside an RV compartment after cleaning and drying it. Use a separate bin or sealed container so it stays away from fresh water hoses, food storage, and clean camping gear.
Does the Camco Dual Flush Pro help with tank sensor problems?
It can help when residue on tank walls or around sensors causes poor readings. It cannot fix damaged sensors, wiring issues, or heavy buildup that needs deeper tank cleaning.
The Bottom Line
The Camco Dual Flush Pro earns an 8/10 because it gives you a practical way to rinse RV holding tanks and sewer hoses without installing a permanent flush system. You should buy it if your RV has a standard 3-inch drain outlet and you want clear visual feedback during cleanup. You should look elsewhere if your drain layout lacks clearance, uses non-standard fittings, or already has a strong built-in tank flush.
