Want to Prevent Frozen Pipes? Here's How.
When outdoor temperatures drop and cold winds blow, your water pipes are in danger. Inclement conditions can cause them to freeze. Or rather, the water inside will freeze, expanding as it does so. The ice thus formed acts as a plug. It blocks the pipe and causes pressure to build up between the

Keeping pipes warm minimizes the likelihood of a freeze. Maintain a home temperature of at least 55 degrees F, even if no one is home. When you are planning to be away for an extended period, drain your water system to stay safe in case of a cold snap.
Plumbing pipes on an uninsulated exterior wall can be warmed by opening the bathroom vanity and kitchen cabinets in the room. This will direct heat from your bathroom or kitchen toward the pipes.
Keep your garage doors closed when not in use to minimize cold air flow. This is especially important when the water supply lines are located in the garage.
At times of extreme cold or when you will be away from home for an extended period in winter, the two best solutions may seem contradictory. The first method is to drain the water completely from the pipes leaving no liquid in the pipes to freeze. To accomplish this, turn off the main valve, and then turn on all the taps in your home. Allow the water remaining in the pipes to run out. When you're ready to reverse the process, turn on the valve and open the faucets, allowing the pipes to refill.
The second way is to let a small amount of water drip continually from the tap. You will relieve pressure buildup -- and therefore, a potential burst -- in the case that the pipes become frozen; the hot and cold water lines should both be left open slightly. To avoid wastage, you may want to collect the clean water from either method and use it to fill your coffee maker or water houseplants.
