I have a shower which has no hot or cold water this cold (2F outside) morning.
I can get to some of the piping directly behind it, inside an attic. There is at least 8-10 inches of insulation between the pipes and the attic.
lost temporarily don't have access to my non-contact thermometer, so I can't tell if these pipes are actually cold enough to be frozen.
Without a thermometer, and without obvious splitting/leaking, how can you determine whether a pipe you have access to is actually frozen or not in the sections you have access to?
