Okay, I have frozen pipes??

[ENG2242]

I have a 2019 TT. Here in Missouri we've had -7 degree temps. I have taken all needed precautions to prevent freezing as I'm a full-timer. I have all accessible cabinet doors open and the furnace is cranked. I know it's frozen on the inside run. Any suggestions that I haven't covered? Also, is the newer plastic water piping less apt to crack? Thanks for any input, David

If your water is all frozen, I mean both hot and cold to all faucets and if you have a compartment that houses all of your connections I would guess that your frozen spot would be right behind that door. If you think about it your plumbing is only 1/2 inch of styrofoam away from -7 degrees.
I know these RV folks say they build a four season unit but most of them recommend you not use it in below freezing conditions.
That being said , if you can determine where it is frozen you can take steps to prevent future problems.
Good Luck

PEX is less apt to be damaged.
Is there a furnace vent in the wet compartment? Make sure it is on.
