2008 Monaco Simba Gas black tank sprayer backflow preventer

[Danny W]

I have been looking for the backflow preventer on the black tank sprayer water line and need a little help.

Is it hiding somewhere on my Monaco Simba Gas 35 SFD?

Any comments would be appreciated and thanks.

It should be mounted up high inside and under either the kitchen sink cabinet or the bathroom vanity cabinet.

That's where both the Windsor and the Dynasty had them located.

It's a vacuum breaker and if bad it is easy to find. It is where your motorhome is flooding from when you try to flush the black tank.

The vacuum breaker should look something like this.

Mine is located in the bath sink cabinet.

I just changed mine on an 06 diplomat. It was located beneath the driver side bathroom vanity sink. I bought a replacement on Amazon for half the price of everywhere else

Thanks to all who responded to my question.  Just as you mentioned, the backflow preventer was located up and behind the drawers in the bathroom.  Thanks again to all!

Have a nice day!
