Minneapolis freezes plumbing in ordinary houses, not only in abandoned ones. Bungalows and ramblers run supply lines through exterior walls, rim joists, and additions that were never warm. A kitchen sink on a north wall goes first. A hose bib left charged splits in the night. A thermostat set back for bedtime can be the reason a line in a cantilever turns solid. When the heat stops, the pipes are next.
Ice dams on these roofs stain ceilings in a way that looks like a pipe and is not. Cold-day stains that grow without a drip under the sink are usually the roof. A wet cabinet under a north-wall faucet is usually the supply. Learn the difference before you open the wrong trade. A frozen condensate line can shut the furnace off and set up a burst by dawn.
Bungalows, ramblers, and cold additions over open air are the usual houses. Galvanized lines crust and then split. Main shutoffs hide in basements and sometimes fail to close. Thaw brings melt to sumps and floor drains while a burst is already on the floor. Mice use the same rim joists as the pipes. Say which one is wet. None of that is a reason to describe every problem as one frozen faucet.
Before you dial, find the main shutoff if you can do it without standing in water. Say whether the heat is on now. Say which wall faces north and which faucet failed. An outside-wall powder room, a dishwasher line, and a sill cock are different spots. Minneapolis will thaw the ice and then show you the split. Lead with the room that is already wet or already dry when it should run.
This cold is ordinary here, and frozen plumbing is what it does to a house built tight to the weather. Do not wait for the thaw to prove the pipe. Name the room and whether the furnace is still running. Pick the trade and call.
