Speaking of leaks

[vbbigsky]

We had a very heavy rainfall with no leaks in the rig when I back washed the black tank the carpet alongside the bed and closet was wet is it possible there is a water line to the black tank in this area

Is your toilet on the other side of the bedroom wall?

Looking at a 2012 floorplan, I'd guess your backflow preventer is the wall between the shower and the pantry next to your fridge. Then again, it may be under your bathroom sink. Kinda hard for either place to get clear over to the bed without a trail.

Going to pull the panel off in the basement and go from there

[vbbigsky]

Yes the toilet is on the opposite wall

Keep us informed on this problem. Since we have the same year unit but not the Big Sky we always like to see what owners have for problems and how they solve them.

It really sounds like the backflow preventer. That would be the only thing that would be charged when you flush and not normally.

The black tank flush port is on the front of the black tank...which is also the front side of your pass-through. Kind of hard for a flush issue to affect an area that is three feet higher. Also there would be no water line runs further forward than your sink in the bedroom. I would believe that the water came from either the window on the slide or that infamous leak source...the one inch wide metal strip on the forward side of the slide right at the bottom of the slide wall. If you pull outward on the outside wiper seal on that side and follow that metal strip back towards the rv wall, I think you will see about 1/2" of it has no silicone chaulk because the assembly worker couldn't be bothered. That was the case on mine...but I saw it before getting water in. And since your washer/dryer prep is in the kitchen, that is a non source as well. Good luck, john

Actually the famous black tank flush antisiphon/backflow preventer valve that fails so often is located high up, either under the bathroom sink or up inside a wall. Pipe goes up, valve mounted at the high point, and pipe goes down to the black tank. When the valve fails/cracks water flows down and spreads out across the floor. I and many others have been there, done that.

Thank you all John I think you might be onto something it was not coming from the window I checked that closely there was no water running down the wall going to pull that rubber seal back and see what it looks like

Sounds like a key another here 4' trim mouldings on the bed room slide if t he carpet is wet in both corners
