how to tell if pipes are frozen
You can usually tell if pipes are frozen by checking for a few key signs in your home, especially when it’s very cold outside.
Quick signs your pipes are frozen
- No water or just a trickle from one or more taps, even when other fixtures work normally.
- Slow‑running water or weak pressure can mean ice is partially blocking the pipe.
- Strange noises like whistling, banging, or gurgling when you turn on the faucet.
- Frost, condensation, or bulging on exposed pipes (in basements, garages, or along exterior walls).
- Bad smells or slow drains , especially if only some fixtures are affected.
If several of these happen together during a cold snap, frozen pipes are likely.
Where to check first
- Unheated areas : basements, crawl spaces, attics, garages, and under‑sink cabinets.
- Pipes along outside walls or near windows, since they lose heat fastest.
What to do if you suspect frozen pipes
- Keep the affected faucet slightly open so any melting water can drip out and relieve pressure.
- Apply gentle heat with a hair dryer, heating pad, or warm towels; never use open flames or extreme heat.
- If you see leaks, pooling water, or a burst pipe , shut off the main water valve and call a plumber immediately.
