Valterra Flush King™ 45 Degree Reverse Flush Valve Attachment for RV, Camper, Trailer

The media could not be loaded. This great product. I have 2017 Salem cruise light. We bought the trailer used. We noticed that the gage wasn't reading right on our black, at least that was our thoughts.this trailer does not have a flush valve or spickit, so trying to get our black water emptied, we would have to fill up a 5gl bucket of water and pour down the toilet to flush it out completely. We thought it was cleaned when the wat would come out clear, and the gage would still read full! I couldn't figure it out. Paid over $200 for someone to come out and flush it.then I seen a TikTok video of this. Well, I thought it would be expensive. I looked for it on Amazon and it wasn't as expensive as I thought. The flush king saved us from having to pay another $200 to have someone come and flush it again. The flush king is simple for both me and my disabled daughter can use. Just connecte it as it is shown, hook a garden hose up and open the valve. That simple. To clean the part was even more simple. Close all your holding tanks, turn water on (with the flush king valve closed) wait a couple of seconds, open the flush valve on the flush king and and keep the water running until rinsed thoroughly. This not only cleans the neck of your holding tanks and the flush king, but your septic hose (stinky slinky) too. If you are a full time RVer, this is a must have. There is also an adjustable sprayer valve for cleaning the tank. I would give this product a 10 out of 10. Much cheaper than having the septic guy do it.❣️

Why did you pick this product vs others?:Loved this flush king device. It went with my rv when I sold it and I need to get another for my new rv. Makes connection of water to flush tanks easy. Adds another new high quality 3” at your dump hose connection.

Must have for your camper!!! Even if you have a black tank flush, this comes highly recommended by RV tank cleaners. It works great and makes sure you have clean tanks. It also works great on your gray tanks. Fits perfectly and doesn't leak at all. Cheap and necessary. Don't hesitate!!

I wish I could give this 10 stars!!!! I recently moved into a new to me trailer full time and I could not get rid of the smell from my grey and black tanks. I would try to flush water down the toilet, by pulling the hose through the bathroom window and putting it down the toilet, but I couldn’t ever tell if the tank was clean or not. Since getting the Flush King my smell has improved 10 fold!!!! Although gross, being able to see what’s coming out of your tanks is SO satisfying and extremely helpful when you’re trying to clean them. I would 100% recommend this as a MUST have if you have a trailer or RV. It’s super easy to install, durable, and easy to use. Best product EVER!!!!

I recently picked up a 45-degree reverse flush valve attachment for my RV, and it’s been a game-changer for the waste tank cleaning process. The installation was super easy—just attach it to the waste outlet, and it’s good to go. The valve feels sturdy and well-built, which I appreciate since it’s something I’ll be using regularly outdoors. The idea behind the reverse flush is simple but effective: it pushes water into the tank at a 45-degree angle, helping to dislodge any waste or residue left behind after the usual flush.When I used it for the first time, I was impressed with how well it worked. The reverse flush really does help clean out the tank more thoroughly by loosening up stubborn debris that doesn’t get washed away during regular flushing. It made the whole process feel quicker and more efficient. I noticed the tank felt cleaner afterward, which is a huge bonus when you're trying to keep everything in good condition. It’s a small upgrade, but it makes a noticeable difference in how I maintain the RV.There are a couple of things to be aware of, though. First, it’s important to double-check that it’s compatible with your RV, camper, or trailer, as it may not fit every model. Also, while the valve is durable, it’s still a good idea to store it properly to avoid any unnecessary wear, especially if you’re frequently out in rougher conditions. Overall, I’m glad I bought this attachment—it’s a solid, practical tool that makes waste tank maintenance much easier and more efficient.

We had a serious clog in our black tank and were able to clear it up and clean out the tank completely. I dropped 5- 1 gallon jugs several times while my buddy worked the Valterra on the outlet and it worked great. Highly recommend it! Had estimates of $200-300 to come out till we found it on Amazon

1st year camping. Didn’t use enough water when flushing and in tank. Waited to long to dump. Purchased this product and worked well to empty black tank. Highly recommend
