How To Prevent Frozen Pipes
By HomeAssist Connect Editorial Team ·
Short answer: Before a hard freeze, insulate exposed pipes, cover outdoor faucets, disconnect hoses, let faucets on exterior walls drip, and open cabinet doors so warm air reaches the plumbing. Know where your main shut-off is.
Before the freeze
- Insulate exposed pipes in the attic, garage and exterior walls.
- Disconnect garden hoses and cover outdoor spigots.
- Shut off and drain irrigation backflow devices per manufacturer guidance.
- Let faucets on exterior walls drip slowly.
- Open sink cabinet doors to let heat reach the pipes.
If a pipe freezes
Keep the faucet open and warm the pipe gently with a hair dryer or warm towels. Never use an open flame. If you can't reach the frozen section, or the pipe has cracked, shut off the main valve and call a plumber.
Why Houston homes are vulnerable
Homes built for mild winters often have pipes in attics and exterior walls. The February 2021 winter storm showed how quickly unprotected pipes can burst during a prolonged freeze.
