Freezing Temps And Tanks Not Draining

I lived in a 5th wheel for five cold winter with temps getting down to zero F. My water pipes froze inside several times without ever a brake.

I had heat tape attached to a hard brown water hose and covered it with 2" foam pipe insulation this heat tape also covered the exposed hose bib.

I covered the valves for both the black and grey tanks and the exposed pipes before the valves with tin foil then heat tape. This kept my valves working all winter.

I always had my grey valve open and connected to the slinky and the slinky rested in an elevated cradle. I never had a problem with this system.

Excellent advice. You covered it all! We didn't get the fresh water hose bib covered and that was the last thing that froze. So far, and we are expecting a 2 degree night, so far only done 15, the Reflectix shielding and drop light have kept the tanks flowing although, in order to keep up and not end up full, we empty the tanks after we shower every evening. The good thing is that we near the office/bathhouse for backup water/toilet "services".

Thanks!
