I post for your approval. The Forest River Floodomatic.

[Ralph_Cramden]

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.....

Im confused when it comes to the brass hose bib style vacuum breaker is everyone using those outside the vehicle correct?

I hook it up to the input on the black tank flush. Then hook hose to it, and hose hooks up to water source.

So, yes, outside the vehicle/TT.

I STILL ASK WHERE IT SHOULD BE LOCATED PER THE INSTRUCTIONS IN AN RV? I AM an expert as it relates to RV's. There are literally MILLIONS of these installed in RV's for the past 20 years. Very few time have I ever seen damage and the damage I found was due to the valve freezing and then the RV'er did not realize he was pumping water into the bath area. Like I stated, just use the Brass replacement. They never leak. And some, are installed thru a floor cut out where IF they leak, it dribbles down to the water bay compartment so you can see it is leaking. THEY ARE NOT A BOOGEYMAN THAT YOU MUST FEAR!!! But, of course, some of you seem to be frightened by them:B I would have no problem having one in my RV. I don't sweat the SMALL STUFF, like some of you:B Doug

I do my own work, but if I were to hire someone, they **** well better sweat the small stuff. Since the stupid, cheap things do leak, place them in a hatch that drains outside or design a hose inlet that incorporates a vacuum break that is external. Junk is junk, sorry that some can't see it when presented to them repeatedly.

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 a Forest River exclusive........Majority of RV Mfgs use that same cheap piece of junk

I personally advocate removal of POS....replace with PVC threaded elbow/pipe and use a hose end vacuum breaker at connection.

When you state "at connection" I take it you mean at the hose bib at the campground that I attach my flushing hose to. (that goes to tank washer connection on trailer?)

This type connector/valve has been required on almost ALL residential outside water spigots for over 30 years. It is designed to STOP backflow(siphon ) of a house water system to the City Water system if there is an outage. Some(Monaco was one) had this on the outside water spigot in their water bay faucets.

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!

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.

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.
