Have a Forest River product, look for this on the line from the black tank flush to the tank, typically in the bath vanity cabinet. Then cut the POS out of there and connect it direct, or if you must replace it with a better vacuum breaker, or just leave it alone if you like living dangerously. It may be the new Forest River floor automatic cleanotron, but it's not listed on the option list.And before you say it......no I am going to contaminate the entire US potable water system.....

Not a Forest River exclusive........Majority of RV Mfgs use that same cheap piece of junkI personally advocate removal of POS....replace with PVC threaded elbow/pipe and use a hose end vacuum breaker at connection.

I have mentioned this repeatedly over the years and it falls on deaf ears. It even says on the manufacturers website that it should not be installed where expelled water will cause harm. Here is one example of my posts.

I am a belt and suspenders kind of guy.

I'll take it one step further. I don't think the tank rinsers work very well.I don't use any of the tank rinser components. I prefer to rinse tanks via the Flush King.

I post for your approval. The Forest River Floodomatic.

He won't let it go. He thinks he is an expert. The reason the Valve makers state this is a standard CYA. RV's have numerous water lines and junctions, that if they leak will cause DAMAGE if not dried out. This poster needs to state WHERE it should be located to not cause damage if it leaks. Doug

From the manufacturers website:
ATMOSPHERIC VACUUM BREAKER/
CHECK VALVE
(571 Vac Chk) must be 6” above flood
rim of the highest fixture connected
to the wasteholding tank. (ASSE
1001-02; device shall not be installed
where the venting of water from the
device during normal functioning will
cause damage.)

I know that some need to defend this industry, but there are a few of us "experts" that understand the problem. Sorry if the facts do not fit into your experience.

It needs to be located in the trash, which is where I located mine.

Not sure of the reason for these pics. They are of anti back flow preventers that go on the outside incoming campground hose bib. Where you connect your water hose. They are not used inside an RV.

YOU are CORRECT......
And that is exactly what I am saying.
Attach it to end of hose then connect to Flush System that way you can get rid of that POS backflow/vacuum breaker junk under bathroom sink that can flood your RV when it fails

Think outside the box!

My Quickie Flush works great with a custom spray pattern tailored for my tank and sensor location. Much better than the turbo models.

Separate pex to a separate inlet so no mix of fresh and waste. And still there are two back flow preventers similar to what old-biscuit posted.
