Sub zero weather; trickle from hot faucets
We're not used to sub zero weather in Chicago. Clearly we have a frozen pipe somewhere, probably in the crawl space. My question is: if I'm getting a trickle of water from the hot faucets, where is that water coming from? Is there always some cold water mixing with the hot (which would explain how cold the trickle of water feels), or is it coming directly from the water heater (which would suggest that the pipe from the heater is not quite solidly frozen yet)? Thanks
