Extended cold snaps in winter are a common event causing frozen pipes and their possible bursting in your home.
In the tutorial Thawing a Frozen Water Pipe I'll describe what you can do to prevent frozen water pipes. Frozen water exerts thousands of pounds of pressure per square inch on a pipe and can burst it, causing flooding and major damage to your home. But there are right ways and wrong ways to thaw out a frozen pipe, and knowing how to perform this critical repair and prevent it from from occurring can save your home.
One of the surest ways to have frozen pipe problems is to leave your hose attached to the outside faucet. So do me a favor and as soon as you are done reading this blog post, check your outdoor faucets and if any hoses are attached, immediately remove them! Then go in the house and if water has not yet been turned off, turn off the water to the outside faucet (also called a sill cock). It is critical to remove any hoses attached to the outside faucet! An attached garden hose is sure recipe for frozen pipe damage this winter.
The sill cock only turns water on and off outside, there is (or is supposed to be) a water shut off valve inside the house for the outside faucet. You may have to do some investigating in your home following water supply lines to try and find the shut off valve. They are usually located near the outside faucet.
By removing any hoses and turning off the water supply to the sill cock you have averted major risk of water damage done by a burst frozen pipe.
