Valterra F02-4350 Flush King for RV Sewer systems

I bought this knowing that a garden hose connects to it, I'd be able to clean it out myself. Initial cost was a little expensive for an individual on a budget, however I am so glad that I went with this one and not others listed for sale. Being able to close the trap and let water fill and rinse out your black water tank is genius. I can do it myself and save money too.

This is so easy to install and keeps you soooo much cleaner with peace of mind. My other gate valves would leak, even just a little which made the hook-ups annoying. Now it's a breeze and this took all of 6 seconds to install.

This works great for blockages. I only wish I had bought it sooner. Tried every other so-called remedy to get my black tank flowing again with no luck. A neighbor told me about this and within 10 minutes of use it worked!

So I got this after watching some YouTube videos about cleaning out the blank tank on travel trailers, especially if you live in them full time. The amount of sludge that can be left behind in a typical cleaning is not great. This allows you to truly clean your tank out %26 get your sensor working again. Must use it with a water flow calculator, so that you don't back fill your tank to the point it backs up into the trailer. It worked like a charm, had to flush my trailer 4 times before it seemed like it was running pretty clear.

I had a clogged grey tank. I used a snake that would partially clear it but would always clog again a week or two later. After using the Flush King I haven't had a clog in over 2 months. I plan to use it again soon to clear any build up that may be forming.

So far, this valve works exactly as advertised. I've read the reviews and I agree that you should not try to use brute force when putting it on and taking it off. I can see where you could damage it if you do. I'm glad I bought it and I hope it works for years to come.

product is as described. easy to use. cleans really good.

Worked great great price !

Great tool that every RV needs

I have a built-in backwash for the black water tank so it didn't do much for that tank. However it did wash out the grey water tank pretty well.
