I cannot remember if it was the hot water or cold water line.
Good luck. I hope it works out okay.

3. Insulate the line in the crawl space - foam pipe wrap is fairly cheap.
Thanks to you both. Last night I went crawling in my crawl space
with a flash light and a borrowed electric hand hair dryer and solved the problem. This is the first time in all the years that I have had the problem. I think it was a combination of the days of very cold temperatures combined with almost no snow on the ground. Snow around the foundation seems to act as a decent layer of insulation.
