Frozen gray and black tank valves and lines.
Looking for some opinions.
I camp in temps below freezing March thru November and the camper works great, except the grey and black tanks valves freeze. I'm looking for options?
I've done a ton of research on the subject and below are my thoughts.
Heat Tape- it'll do the job and needs to be wrapped.
Concern- fire. Plus it won't protect the valves should a tire shred.
Box in the drains/valves- but what do I do for heat?
Heat Tape? Small electric heater with tip over protection? Run a vent line of the furnace? The first two are fire concerns. The last may be a challenge to run the hose.
Thoughts, opinions? How did you solve a similar problem?
