Flush valve allows you to rinse out your wastewater tanks and flush out your sewer hose, breaking up clogs and cleaning tank sensors. Built-in backflow preventer keeps water source contaminant-free. Clear barrels shows when tanks are clean.Who decides on size of box for shipping and do you train them on securing product for shipment? I ordered two wiper blades, two heater door clips, sewer flush king and sewer cap. They were shipped in a huge box (21"x26"). So big that the flush king came out of its packaging from being tossed around inside the box. I'm sure everything was bounced around the entire trip to my door cause there was only one small strip of filler for cushion and the box was crushed onretailer. It could have been shipped in a box half that size. I'm actually not expecting my flush king to stay together long. Disappointed in the shipping package. I guess you take your chances. I never expected this from etrailer.
I have not had opportunity to use the unit yet, but did take it out of box and installed unit. The picture on web site makes it look like the valve gate would be against the exisiting pipe, but it is just the opposite. When installed on my Terra Oasis, it sticks out past the trailer tire, so I don't think I would want to leave it on while traveling.

Works just as it should. It’s really nice to see what’s going on when you dump the tanks because without this valve you really don’t know.
Works great, if you don't have a black tank flush port on your trailer.
VERY impressed with product, my first time "back-flushing" the black-tank & was impressed with the amount of dried toilet paper flushed! A+++
I had one of these and just loved the way it worked and helped me be sure my holding tanks were clean and empty. Unfortunately, on our recent trip something apparently came up off the road and made it disappear as well as breaking a fitting on the line coming from the trailer. I've gotten so used to using this that I really hated to dump without it.
We buy quite a bit of things from Etrailer for our business equipment and my RV. Always get good service.
I love this device. Really gets my tanks flushed out. It’s very easy to use.
The Flush King worked like a champ! I was able to flush out my black water rv tank and not get not get dumped on in the process. I really liked the fast delivery by etrailer also! Great company to do business with!
I purchased the Flush King device to solve a problem I had with Black Water Valve not closing all the way. I suspected some type of debris was causing the gate valve to not seat correctly. The Flush King device allowed me to back flush the line near the source of the problem and the dump valve is now working great. Every RV owner should have access to the a Flush King device to keep your dump tanks free and unobstructed.
I also purchased a wand so I can flush the Black Water Tank from above. This is a great tool for cleaning sensors and pipe between toilet and tank.
This made dumping much easier
Wow this thing works! I not only cleared a black tank stoppage that prohibited the black tank frm draining at all, I cleaned both the grey and black tanks...
My neighbor is using it this week to clean his tanks as well - this is a device that is now built in to some of the newer RVs, because its needed and works so efficiently,,,
SCOTT W - 07/31/2020I haven't used it yet but it does look to be exactly as advertised except it did not come with with the backflow preventer. I am excited to try it on our next trip out in a couple of weeks. I'm knocking off one star only because it was missing the backflow item.
Brooke M - 10/21/2021Excellent service. One item was back ordered and they gave me the opportunity to choose another item. I wanted to wait on the item. They keap me updated. Thank You.
Looking forward to trying this out on our next camping trip.
The valve made flushing both tanks easier than putting a hose inside the camper trailer.
Product worked great. Black water tank was clogged bad. Paper had dried hard over drain. 1 place told me I needed another tank. Another place put chemicals in but that didn’t work. I tried snakes and nothing worked. The flush king blew the clog apart and everything worked flawlessly. Great product
Great product. I backwash every tank Black and Gray. My black tanks have interior sprayers. Between the flush king and sprayers my tanks are ready for a long winters nap. No smells...
Works great for our fifth wheel that didn’t come with a factory installed black tank flush system. Use this every time we are done camping and the smells are gone and tank sensors read as they should. Well worth the money!
Really helps see when draining is complete. I also like that I can force water back into the tanks to help rinse them out. Water valve hard to use with gloves and sometimes leaks.
I just received my order this afternoon. Very surprised at the speed with which it was delivered. I am in the process of rebuilding a older5th wheel and the items that were ordered are just perfect for the job.
Thank-you etrailer I will be back
Used one time. Worked PERFECT!!!! Wife was ecstatic!!!! WE had a black tank that wasn't draining. Installed the device. pressurized the system and it blew the clog out. Back washed a couple times, haven't had a problem since. Anyone who owns an RV should have one. Wish I had found it sooner. Thank you
.
Have not yet used the gated sewer valve that I ordered but was able to borrow one from a friend and was very impressed with how well it works . know it will serve me well.
Very pleased with price and quick delivery.
Quick shipping and service. I knew where my order was from day one till received.
ETrailer service and delivery was great. Will use you again. Thanks
The best trailer accessory ever. It is working great after a year. No leaks. Versatile. Rotates to accommodate the various geometries of the curbs at dump stations. Two back flushes usually gets everything cleaned out of the black tank. The clear pipe shows it is working perfect! If this ever breaks I will buy the exact one again.

45-Degree flush adapter lets you to rinse out your wastewater tanks and flush out your sewer hose, breaking up clogs and cleaning tank sensors. Built-in backflow preventer keeps water source contaminant-free. Clear barrel shows when tanks are clean.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.
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.
Victor - 06/12/2019I’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.
As described !!!!!!!
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.
The concept of the product is overall good, but the piece where the nozzle goes into the adapter is a little problematic. It has to go in there just right or it could be damaged. I wish the manufacturer would address this possible problem, and make that area of the adapter beefier
units works great. Helps to identify when the tanks are running clear. I would recommend this unit.
etrailer gave great support and service. I would recommend them to anyone!
Received the products on time.
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
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.
I have a long drain approach, and this items is very hand in cleaning out the line itself.
Very satisfied with everything we purchased from etrailer!
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.
I have not had the opportunity to use this yet. It is very solidly constructed and was shipped super fast.
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!
I prefer this product to the type that that advertises both hose & tank clean out. I get a much better tank clean out, and I can put a cap on it and rinse the hose as well.
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.
Prompt shipping; products were as described. Looking forward to using it!
Works good
Jack R - 03/22/2019Received everything promptly and still using today. +A
