CLEAN AND EZ
THIS IS A MUST HAVE FOR ANY RV'ER. GOT A 10FT WATER HOSE I LEAVE ON IT, ALONG WITH SEW HOSE! SO FAST SO CLEAN SOOOOO NICE!!! THE CLEAR WINDOW MAKE IT EZ TO SEE WHAT YOU'VE BEEN MISSING. YOU'LL BE HAPPY YOU GOT IT. OTHER CAMPERS WILL ASK YOU ALL ABOUT IT SAYING THEY HAVE TO GOT ONE.

Works great and ensures a clean tank.
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

Amazing!
This thing works amazing like other reviews say. Iv tried the wands and all the tank blaster chemicals, nothing compairs to how well this works. It gets more crud out than ever imagined that was still in there. I did a regular dump after camping and then used this to do a back flush. I was amazed on how much was still left in the tank and come out after the back wash. The pressure and vortex this makes once you open the gate to let all the water out is very impressive and satisfying to watch. I did the back wash 4 times to get 10 years of crap out of my tank. I like how it swivels as well. The first time you go to swivel it, it will be rather hard but it gets easier as it gets worked in.

Great product❣️
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.❣️
