Plumbing in Minneapolis freezes in lived-in houses. Supply lines run in exterior walls, rim joists, and cantilevers over cold air. The first faucet is often the kitchen on the north wall, then a powder room, a dishwasher, or a sill cock with the hose still on. A setback overnight is enough. A furnace that quit is enough. The split often waits until the thaw, so the cabinet looks fine until it does not. Find the main shutoff before you describe the rest.
Say whether the heat is on at this moment. Say whether you opened the cabinet or left a trickle, and whether that changed anything. Those are facts, not a repair plan. An ice dam can wet a ceiling and look like this call; if every faucet runs and the stain is upstairs on a cold day, say that so the roof is not ignored. A hose bib that split is the exterior wall. If the main will not close, say so.
Galvanized lines in bungalows crust, then pinhole, and a pinhole is not a freeze even when it shows up in winter. Describe what you see: a split with ice, a green crust, a drip at a radiator valve, or sewage at a floor drain. Ejector pits and sumps matter when melt hits a basement that is already wet from a burst. Roots and a bellied clay lateral back up a lower tub when the washer drains. That is not a frozen faucet. Keep the symptoms in separate sentences.
Water heaters fail on the morning everyone showers, sometimes after a night of recovery in a cold basement. Know gas or electric, and whether a pan exists. Shut the supply if the tank is flooding, and say that you did. A high-efficiency furnace condensate line that froze is a heating problem that becomes a plumbing flood when it lets go. Garden-unit or basement baths on outside walls freeze when that room was closed off. Say if the room was sacrificed to keep the rest warmer.
Lead with the room, the wall, and whether water is running, frozen, or already on the floor. Say if the furnace is still on. Minneapolis thaw is when a silent freeze becomes a flood. Call the number on this page.
