The clearest sign is a faucet producing only a trickle — or nothing — during freezing weather while other fixtures work normally. Frost or condensation on exposed pipe, banging or clanking when you run water, and unusually cold spots on walls or floors are the others.
The Signs
- Reduced or no water at one fixture. The most reliable indicator, and it isolates the frozen section to a specific run. If nothing works anywhere, the freeze is closer to where water enters the house.
- Frost or condensation on exposed pipe in a garage, crawlspace, attic, or under a sink on an exterior wall.
- A pipe that looks bulged or distended. Treat that as urgent — it is under pressure and close to failing.
- Banging or clanking when you open a tap, as water forces past a partial ice blockage.
- Odd odors from a drain or toilet, which can happen when a blockage forces air and gas back the wrong direction.
- Unusually cold areas on walls or floors, pointing at where cold air is reaching the pipe.
Where to Look First
Nearly every New Mexico freeze failure happens in the same places: uninsulated pipe in exterior walls, attics, crawlspaces, garages, and unheated additions — plus exterior hose bibs, especially with a hose still attached, which traps water right at the valve.
What to Do Right Now
Open the affected faucet to relieve pressure — this genuinely matters, because pipes burst from water compressed between the ice and a closed tap, not from the ice itself. Locate your main shutoff and confirm you can reach it. Then apply gentle heat from the faucet end working toward the blockage, using a hair dryer, heating pad, or space heater at a safe distance.
Never use an open flame. No torches, no propane heaters aimed at pipe. That causes house fires and can flash trapped water to steam and burst the line violently.
Watch for Damage as It Thaws
Cracks frequently reveal themselves the moment water starts moving again. Stay with it while it thaws.
