Faucet had a icicle waterfall. Never noticed it dripping during warm weather. No hose attached. Is a frost free with vacuum breaker cap thing on it. Went in crawlspace, no valve to it.... (One in front yard does).
First day, pipe in crawlspace was just cool. tonight the pipe is pretty cold. Not like painfully icy, but not good to see a big increase in coldness.
Until I can get someone to come mess with it (Anyone in my area guys?), would wrapping the pipe in a heating pad stave off it freezing and bursting? Copper pipe leads to plastic piping. (At my old hospital I knew of a door hatch that had electric heating cord we had to leave open and plugged in every winter around some pipes.)
