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

I'm a first-time travel-trailer owner and this thing has changed my life! As a newbie I had no idea how cleaning out the tanks was supposed to work and so I just started trying things: Plug in the hose to flush spot, and turn it on while opening and closing the valve, blindly hoping something was happening.The Flush King changed everything. Backflushing makes so much more sense, and being able to see the "effectiveness" of the cleanout is super helpful. This is really just a nice way to say I see poop coming out, but whatever... I know it's gross, but what's more gross is the idea that I would have kept all of that building up in my tank before I had the King!It's super sturdy, haven't had any leaks, it's what I recommend to new travel-trailer or RV owners I see doing what I used to do!

This is the second type of back-flush attachment I have tried the first orange one with a 360 swivel blow apart on me while flushing, not the best experience. I figured this was due to the weakness of the swivel design, so this one being fixed does not have that potential flaw. I have to say on receipt I was impressed just how well made a sturdy this was, look stronger than the previous one. Having now given this a good test, I have to say, get one. The amount of additional waste I flushed was shocking, but I also noticed that I did not get any unpleasant smells while camping. So a really clean tank is a happy tank. I only have a small trailer, so smaller tanks, but back filling did not really take much time at all, flow from the hose attachment was significant and strong, enough to flush more out without back-filling. If you want a clean tank get one, then you'll wonder why you never purchased one sooner. Now for the observations; I found it a little annoying that the hose connection brings the hose right over the main dump valve on the device. While it does not stop you using it you do need to turn the valve handle 90 degrees to open it as the hose is in the way. Just wondering why they did not offset the hose connection and valve by 90 degrees, it does look like something you could do yourself, but its does not affect functionality. The other observation is one of time, to do the backflush it does take time and if its a single dump station you can end up with people waiting. I performed 2 full back flushes last time out which takes around 20-30 minutes with the initial dump, so allow for that. That said we waited for the trailer in front of us to dump and use their internal flush system, which was not much quicker anyway. Would recommend, but please get a separate hose for this only as we have seen people using their fresh water hose, which is not to be recommended, we have the bright orange hose so there's no mistakes. Happy camping

Good quality fittings and valves. I also purchased a water flow meter to back fill my RV tanks without overflow. Good product.

Flush King works awesome and is easy to use. When you use it make sure you install a gallon counter and know the size of your Black and gray water gallon size.

The Valterra Flush King™ 45 Degree Reverse Flush Valve Attachment for RV is a lifesaver when cleaning out those pesky black tanks that hold onto extra tissue and debris. The Flush King makes cleaning those tanks a breeze. It is easy to connect, run water back up into the tank, and flush it all out. I just wish I had this years ago. I highly recommend this item to anyone with an RV/camper who needs to clean those tanks out regularly - anyone with an RV/camper. :)
