The product worked perfectly and came q uickly.
Great product for price
System works very well.
I'm getting exactly what I ordered in a timely manner and it is of good quality. Thank you
It works very well to help flush the black tank it is very durable and well made. With the check valve installed that comes with the unit it is also a very sanitary method to flush the tank
Worked well to help flush black tank. Problem is on my trailer, three drains combine into one outlet. The flush only worked with the black tank which was in line with the outlet. The two gray tanks are on a lateral and the water did not appear to get up into these tanks. The flushing did not clear my tank sensors. All three tanks still show full when all tanks are completely empty. Sensors may be bad. Product does help clean out the black tank as intended. Easy to use, only issue was leak on check valve to hose connection.
Don’t waste your money or time, these things don’t work. You turn the hose on full blast the water goes in a little ways and comes right back out. You’re better off just filling your black tank from the top and then open the valve to force flush the tank. Do this when you’re at the dump station
Just as advertised
A pain to use. Stinky slinky has to be held at a height greater than the elevation in the tank you want to flush to.
I used it once. It worked OK. Just be prepared to prop up the hose while the water flows.
I have an older RV with no tank flushing system. This has worked well.
Exactly what I wanted
Easy installation and flush system works great, would buy again
I've watched videos on using this adapter for flushing tanks and hoses on Youtube. So this one looked like a good one to order. Arrived in great condition and seems well made. I'll probably need to re-watch a few videos again to make sure I get the hang of using it. We bought a 22 year old RV and figure it will need deep cleaning into the tanks not just the interior and exterior areas.
I had this Valterra Hydroflush on my previous camper but thought I’d give a similar Campco product a try. The Campco did not provide the rinse force needed to do a good job rinsing my holding tanks. So back to the Valterra which has the necessary pressure. Highly Recommended.

After a year working fine with no leaks.
The quality of all the products and accessories I have bought at e-trailer for my trailer conversion project is great:
EZ Coupler RV Sewer Hose Kit w/ Swivel Fittings and 4-in-1 Clear Adapter - (2) 10' Long Hoses - D04-0115: Great Hose and couplers!
Valterra Hydroflush Reverse Flush Adapter for RV Holding Tanks and Sewer Hoses - 45-Degree - F02-4100: Awesome solution to clean up the tanks thoroughly!
Valterra Waste Valve for RV Black Water Tank - 3" Spigot to 3" Lug - T50A: Great valves so far!
Scissor Stabilizer Jack - 18-3/4" Travel - 2,500 lbs - Qty 1 - TJSC-24: Great product, performing as expected.
I have to say at the outset that I use this with another gadget that attaches to it. The second gadget is a valve that allows me to stop the flow down the sewage line. Together, they accomplish two separate things.
If the plumbing really gets jammed, closing the valve, and running water into the Hydroflush, forces the jam back into the tank, thus loosening it. DON'T DO THIS IF YOUR TANK IS FULL, UNLESS YOU WANT A REAL MESS IN YOUR BATHROOM, OR WANT TO BLOW UP A TANK.
The second useful thing you can do with this rig is open and drain your sewage (black water) tank, then close the valve on the gadget. Finally, with this valve closed and the black water valve still open, open your gray water valve. Gray water will try to get down the sewage line, and be blocked by the gadget's valve. Then it will flow backwards into your black water tank. After a couple of minutes, open the gadget's valve and watch all the gunk flow out of your "emptied" black water tank. This is a great way to help keep that tank cleaner and flowing well.
Of course you could do this by connecting a water hose to the Hydroflush, but it's more work.
The Hydroflush is a great, and well made product. It also lets you see what is really going on with your system.
Do you have a question about this RV Waste Valve?

We used it once last year to clean & flush out the black tank. The end did not loosen or get lost in the tank but once it hung up trying to pull it out. So in the future I intend to add a clamp to insure the tip does not come off like others have had happen. But it appears to be firmly held in place. Turned out our grey tank seemed more dirty than the black tank which means past owners of the 22 year old RV ignored it and only focused on the black tank. However a good device to help insure the tank stays cleaned out.
