Flush King Reverse RV flush valve provides you with the quickest and most effective way to fill, rinse and remove residue from your black or gray holding tanks.


Flush King rapidly refills the holding tank no matter what height of tank or angles in plumbing. Unique design eliminates messy wands and hoses inside the RV by allowing you to reverse flush your tanks from the outside.
  • Powerful performance removes clogs in drain pipes and improves sensor performance for more accurate readings.
  • Four locking hooks provide a tighter seal to guard against leakage.
  • For your convenience, the handle swivels 360 degrees to make hook up and operation easier.
  • The innovative clear barrel allows you to see when the tanks are completely clean of residue, so there is no guess work.
  • Flush King fits all Trailers and 5th Wheels and most Motor Homes and is not a permanent attachment.
  • Twist on and off, how easy does it get!

    We've been using the Flush King for a number of years now. I would not be without one. It's easy to use and it works! We use it every time we are hooked up and it is part of our packing up to leave routine. It does help to have someone inside the trailer while you're filling the tanks up to re-flush the system. That person can watch the level of the tanks and advise when to switch to another tank -- yes, it is great for flushing grey water tanks as well! A couple other reviewers have mentioned the plastic getting a little brittle with age. That happens to all plastics. I just make sure I turn the device smoothly and gently while hooking and unhooking it -- ours has lasted a long time. I'd buy another in a heartbeat!

    The Flush King opened up a black tank pipe blockage very easily and with no mess. It also does a great job or rinsing out the sewer hose. No matter what, emptying the sewage is no fun and not so clean but this device makes it a whole lot cleaner with the hose. I did have to buy a 90 degree water hose adapter to be able to use this directly on my camper sewage outlet. From now on, I will always use this when connected to a sewage dump.

    We have owned this unit for 8 years now and it still works like new. We bought a used fifth wheel the first time out used the flush king and WOW you would not believe how much build up came out. We use it every time and have never had a problem with our tank probes not reading correctly. Worth every penny!! Happy Camping

    An RV Must Have!!!!!

    Have had my trailer for 7 years, thought we were doing a very good job keeping the tanks clean and well flushed...... WRONG - Not until we used the Flush King did we realize how the tanks were NOT well flushed. After flushing the Black Tank 6 times, we FINALLY got an EMPTY reading on our gauge. Fantastic product!!!!! Will use every time we have FULL hookup. When reading the box it comes with a WARNING!! Make sure when using the Flush King that when you turn on the water to flush the tank that you have the Black tank valve (or Gray) OPEN before you turn on the water or you will blow the gasket on the Flush King (we learned that the hard way) I called Flush King in California to request a repair kit and the service I received from them was Fantastic - GREAT company to deal with!!

    We are new RVer's and learning as we go. This item has made cleaning our tank so easy. We had no problem even the 1st time of use. The clear tube is great.

    As a fairly new RV'er. I was intimidated by many rv tasks, the toilet being one of them ...this product is outstanding, easy to use and gets the job done...I was getting some false readings on the black water gauge and thought I was doing and adquate job cleaing and maintaining the tank ...Boy was I wrong !!! The first time I used this (after cleaning with a wand as usual).I was AMAZED at what I saw ......id give it 10 stars if I could.

    My second camper kept reading 1/3 full each time I dumped the black water tank. I purchased this and used it and I was amazed at what was left in my tank and after using it my tank read empty. I have recently purchased a new camper and I use this product everytime I empty the tank. It is easy to use and no mess. I recommend anyone who owns a camper to purchase and use, you just think your tank is empty until you use this product.

    Plan on replacing after a few years.

    June 20, 2011
    I agree that the Flush King should be a standard item for any RV as it gets a black tank cleaner than any other item we have used. Just be careful not to overflow your tanks while back-filling them. However this product does have a life expectancy of about 3-5 years as we are about to purchase our 3rd one in 6 years. The plastic tends to get brittle after a few years and in our case the water inlet valve has broken off leaving the unit totally useless. I have noticed other issues that have been mentioned in other reviews that again shows this product has a very limited life span. This item is also a bit pricey to only last for a short time. Like with most good ideas, poor quality can subtract from the overall satisfaction so I am rating as a 4.

    I have used the Flush King since 2006 and it really does a great job of cleaning out my tanks! I had the same issue with a faulty seal as one of the other reviewers mentioned but I called the Customer Service number printed on the label on the front of the unit and they sent me 5 seals by Express Mail. It took me about 5 minutes to replace the faulty seal and I have not had a problem with it since then. I would strongly urge anyone with a camper to have one of these handy little devices!
