A deep freeze is coming! Don’t let your pipes burst this winter.
Here are a few tips to make sure you don’t have a big mess (and bill!) on your hands.
Set home thermostats above 55 degrees during cold weather.
Drip cold water in farthest faucet from your main valve. Moving water keeps pipes from freezing.
Find shut off valves for emergencies.
Insulate pipes in unheated areas.
Open cupboards and vanities to warm pipes.
Keep outsides valve open so water remaining in the pipe can expand without causing a break.
When freezing weather is coming, turn off water to outside spigots and drain all water from the line.
