It took a littler long to get here but have to consider the state of our country i have ordered thing from her a few time and i love there products and services and have already referred others thank you
Well made, will get the job done.
Works good
My order was processed and shipped the same day it was received. It was delivered as scheduled and was exactly as ordered. Phenominal job!
fast free delivery. I have not used this particular product yet but have had one in the past it really helped to keep the black tank clean. You can actually see the debris as it comes out so you know the product is cleaning out left over debris and sewage.
etrailer gave great support and service. I would recommend them to anyone!
Received the products on time.
Prompt shipping; products were as described. Looking forward to using it!
I have a long drain approach, and this items is very hand in cleaning out the line itself.
This thing works a little to well. It cleaned the black water tank great. It made the gage work again. I wouls highly suggest this product. It works awesome.
Excellent product. Fast shipping
would give it 5 stars but haven't used it yet I believe its just what I need to clean out the tank at the dump station plus with it being clear will be able to see when tank is clean!
We like the clear connection and the added rinse/flush power when using built in tank flush on our TT
My order arrived promptly, but I have not had time yet to use it. My Friend Ron swears by it. I will add a more complete review when I use it.
Very satisfied with everything we purchased from etrailer!
Nice product and thoughtful design. However, on mine, a little plastic part at the top that serves no obvious function other than perhaps to add a holding strap was broken. It does not affect the use of the connector but it is upsetting to get something new with a broken piece.
I’ve now placed my 3rd order with etrailer; each order has been promptly filled and has arrived sooner than my expectations! etrailer has now become my “go to” company for my RV needs.
Additionally, their prices are some of the most competitive around.
Easy installation and flush system works great, would buy again
Exactly what I wanted
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.

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.
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.
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 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.
I have an older RV with no tank flushing system. This has worked well.
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.
Looks well built. I’ll let you know if it breaks. Yuck…
