Backflow preventer location?
Anyone know the location of the backflow preventer on a 2013 CC 36 CKTS? I having low water pressure and some dripping in the big storage area. I’m told my unit has one of theses valves somewhere. There are 2 blue lines going up through floor. I see water dripping from them when I us the black tank flush.
Not sure what’s happening?

The medicine cabinet to the left of the sink.
I have a 2013 CKTS.
4 screws held this cabinet in, I pulled it out and the vacuum breaker was right there.
Good luck, let us know how you make out.

Can’t find any screw heads in our cabinet. Where are they located in yours? Thanks

They were behind the facia that goes around the front of the cabinet.
Just inside behind the facia, 4 of them I believe.
Two on each side, top and bottom.

If behind the front facia trim, how did you get to them? Thanks

When I say behind the facia, I mean inside of the cabinet behind the facia.
I would think that they would be kind of obvious, unless they secured the cabinet some other way...
This is not the cabinet, we are not at the RV now, but it's the same idea...
Top & bottom, maybe not quite in the same location. (4 of them)

Thanks. Do you know if thats a backflow preventer or a simply a vent valve?

If you're talking about the black tank flush line, the apparatus is a vacuum breaker/check valve (back flow preventer). Here's an example.

Dam , can’t find a mounting screw anywhere in or on the cabinet. Unless its glued or used wood filler to cover up screws on the face trim. This is aggravating. It has to behind the cabinet. I hate to tear up this cabinet trying to remove it.

If you leave your black tank flush hose hooked up that valve will drip a lot. I found that out the hard way.

Good tip. I disconnected the hose from BTF in the utility area. That must mean the valve faulty?

Most posters here are discussing the anti-syphon valve on the black tank flush line. While this could fail and cause a drip it has nothing to do with the water pressure in your fresh water system. Exactly what problem are you trying to fix? Low water pressure or a drip in the black tank flush?

I’m after the drip coming from the two blue lines going up through the floor.

That's tough to diagnose without seeing where those lines connect but it doesn't sound like the black tank flush.

Why not?

Perhaps you are correct. I now see he indicates this occurs while using the black tank flush. However this would not create low water pressure. That is most likely a different issue.

No. That means it is drawing left over water in the hose and it is escaping out that valve creating that drip on the floor in your pass thru.
