Thats exactly how my Cardinsl is plummed. The nackflow prventor on mine is accessable behind the shower valve. I replaced my sprayer with the rotating one available at Camping World, works much better.

Fixtures with traps and vents must be provided to protect against siphonage and back pressure.
Vents to release gases from any waste holding tank must be provided.

Check Valve is a modification to a code requirement. A step but not replacement for the Vacuum Breaker.
Never said there was no code for the install of these systems. It is in fact referenced on the document I posted. I just said that because of the routing of the tubing in my RV cleanout, in my opinion, the backflow preventer is an over kill. It's just an opinion and everyone has one of those. The cleanout is only used when emptying the tank and it's empty when finished and I cannot see how any backflow from an empty tank can get to the input spigot where pressure was previously applied. That's all.

Suffice to say a backflow preventer is required by code. If it wasn't, FR wouldn't install it. There is a direct connection between the black tank and the campground's potable water supply system so the water supply system has to be protected from contamination.

I use an external brass one like the picture B & B posted because the original owner of my TT removed the factory version.

This does happen in real life.

Google Walkerton Ontario...

7 dead due to Ecoli...same as missing back flow preventer can cause.

When this is removed it creates a hazard for others. If you choose to do something like remove your LPG protectors that is more or less a hazard for you unless the trailer blows up and sends shards of metal at your neighbours.
