Video Transcript for Flush King RV Sewer - Hose Adapters and Fittings - F02-4350 Review

Today we're going to be taking a look at the Flush King Reverse RV Flush Valve. This is designed to remove clogs in the drain pipes and improve sensor performance. It also eliminates the need for wands and hoses being used inside the RV. This is going to refill and flush the tank at any height or bend of plumbing, and it attaches quickly and easily. It's going to use the four locking hooks for a secure connection. It's a standard bayonet style fitting. Then the handle is going to rotate three hundred and sixty degrees for easy connecting and accessibility, so it's really nice design of the unit. It's also going to feature the appropriate seal in there for a leak proof performance.

We're going to have the three inch gate valve right there as well. That's going to have internal seals for leak proof performance also. Now on this side is where you would connect your drain hose. This is the side that connects to the connection point on the RV. It's going to feature a built-in back flow preventer, here in the connection point here. This connects to the water hose, then you've got that ball valve system right there with the blue handle.

It's very easy to open and close to control water flow. It's also going to come with an anti-siphon valve to protect the fresh water supply from possible contamination. This unit installs at the fresh water supply faucet. Now using the unit is quick and easy. All you've got to do is remove the waste valve cap and attach the Flush King Valve, the clear end, to the RV's sewer connection. Then attach the sewer hose to the Flush King, then to the sewer or the dump station.

Then you'll need to connect the water hose to the Flush King shut off valve. Open the Flush King valve and black water tank waste valve to drain the black holding tank, and then turn the water on, open the valve and fill the holding tank to the desired level. Then you can reopen the Flush King valve using that nice T-handle design right there to drain the tank. Then you can repeat that process as necessary until the discharge water is clean. That's going to do it for today's look at the Flush King Reverse RV Flush Valve..

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. 431722

Being a full time RVer, we have had issues with the sensors not clearing on our gray tanks due to no option to flush. Was able to get both gray tanks cleared to empty with minimal effort. Will be purchasing another as I have 2 locations for tank draining and will definitely recommend to others. 504465

Product was delivered promptly and appears to be exactly what I need. I have not needed to use it. Hopefully I will never need it but if my black water drain does clog up again, I feel very confident that this will enable me to clear relatively easily. 436053

I had a clog in the outlet of the black water tank. I ordered this from George on a Sunday. It shipped on Sunday much to my surprise. Came to me in excellent condition. I hooked it up and it worked as advertised. Cleared the clog and cleaned the tank. I flushed it about 3 times and was getting clear water. It also cleaned the sensors so the tank is showing empty. Its been 2 years since they have worked. Excellent product and excellent service 428499

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 584778

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. 563950

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. 563551

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! 550770

Received and used Flush King today. Works excellent, this is the newer version, water is directed toward the Grey and black tanks and not toward the shut off valve., I was surprised how much came out of the Black tank. 338439

Ask the Experts about this Flush King RV Sewer
Do you have a question about this RV Sewer?


  • Recommended Sewer Hose to Use with the Flush King Reverse Flush Valve # F02-4350
  • I recommend using the Viper RV Sewer Hose Kit # D04-0475 to use with the Flush King Reverse Flush Valve # F02-4350. This sewer hose kit come with two 10' hoses so that you can just use one if you are able to get closer to the dump site. I also recommend using the Sidewinder RV Sewer Hose Support System # CAM43041 from Camco which will hold your hose and has a slight slope to it so that you don't have to constantly be lifting the hose to make sure everything gets to the dump site.

  • Recommended Rinse Hose to Use with Flush King Reverse Flush Valve
  • For a standard flushing hose that will work great with the Flush King Reverse Flush Valve # F02-4350 referenced in your question, I recommend using either the 25 foot Valterra Hose # W01-4300 or the 15 foot # W01-4180. These will work perfectly with this valve and allow you to rinse out your wastewater tanks and flush out the sewer hose. I have attached a short video demonstration on this product that you can also check out.

  • Black Water Flush Valve for Black Water Tank Access at Tight 90 Degree Angle
  • The Flush King Reverse Flush Valve # F02-4350 will work for a tight 90 degree angle but there are other options that would work better such as the Valterra No-Fuss Flush with Check Valve # A70 which would get installed in the side of the tank with the access on the outside of the trailer/RV wall.

  • Replacement Seal For Flush King Reverse RV Flush Valve
  • I called my contact at Flush King and they told me the replacement seals you need are part # T1003-9VP. These are the seals that go between the clear plastic waste tube and the body of the waste valve. If this is not the gasket you were asking about let me know and I will see if I can find the gasket you need.

  • Is the Flush King Reverse Flush Valve Good to Use for a Black Water Line with Two 90 Degree Elbows
  • Since you have two 90 degree elbows in your black water line I recommend using the Camco Tornado 360-Degree RV Holding Tank Rinser # CAM40126 because it will be much more effective at cleaning your holding tank than the Flush King Reverse Flush Valve # F02-4350. The Tornado installs in the side of your tank and has a 360-Degree rotating head with 10 high-pressure nozzles which reaches every area of your holding tank. This also comes with a 6' long hose to give you easy access and a built-in...

  • Does Valve Handle Swivel on Flush King Reverse Flush Valve?
  • Yes, the valve handle can go sideways on the Flush King Reverse Flush Valve # F02-4350; in fact it swivels 360 degrees. I've added a link to a video review of this product for you to take a look at as well.

  • Can Lubricant be Used on the Valve Handle for the Flush King Reverse Flush Valve # F02-4350
  • You can definitely try using some lubricant like WD-40 or our equivalent, the UltraLube Biobased Spray Lubricant # L10444, to see if it will loosen up the handle. Since the mechanics for the handle on the Flush King Reverse Flush Valve # F02-4350 are really simple it shouldn't take much more than that. You will just want to work the handle a little after spraying it to make sure that the lubricant spray spreads around a little.

  • Can Flush King be Permanently Mounted
  • The Flush King Reverse Flush Valve # F02-4350 should work great for you but I do not recommend permanently mounting it. I have heard of some people doing this but to get the best, longest-lasting use out of this I highly recommend only using it when needed as opposed to keeping it on when you are traveling. I have added a link to a video review of the Flush King for you to take a look at.
