Pipes most at risk for freezing include:
- Exposed pipes in unheated areas of the home.
- Pipes located in exterior walls.
- Any plumbing on the exterior of the home.
A frozen garden hose can cause more damage than a busted hose; it can actually burst an interior pipe. When the water in the hose freezes, it expands, increasing pressure throughout the whole plumbing system. As part of your regular seasonal maintenance garden hoses should be disconnected, drained, and stored before the first hard freeze.
If you don’t have frost-proof spigots, close the interior shut-off valve leading to that faucet, open and drain the spigot, and install a faucet insulator. They cost only a couple bucks and are worth every penny. Don’t forget, outdoor kitchens need winterizing too, to prevent damage.
Exposed interior plumbing
Exposed pipes in the basement are rarely in danger of freezing because they are in a heated portion of the home. But plumbing pipes in an unheated area, such as an attic crawl space and garage are at risk of freezing.
