How to Prevent Frozen Pipes

Frozen pipes can be a household nightmare. A few inexpensive items and a few preventive steps can help you avoid the problem.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Electrically Powered Heat Tape
• Duct Tape
• Heat Lamps
• Twine
• Twine
• Caulks
• Insulation
• Insulation
• Duct Tape
• Insulation
• Insulation

1. Apply electrically powered heat tape; this will ensure protection against frozen pipes in the coldest weather as long as the utilities are on. Apply the tape in a spiral pattern following the manufacturer's recommendations regarding the distance between individual coils.

2. Warm the area with a heat lamp if all the pipes are concentrated in one small space.

3. Use foam rubber or fiberglass insulation (see Tips below) to cover all exposed lengths and joints of the pipe if electrical solutions are inappropriate. (If you've used heat tape you may need to go up one size in fiberglass insulation covering to get a proper fit.)

4. Secure the sections of insulation with tape as needed.

5. Prevent drafts of frigid winter air. Secure all crawl space openings or windows and insulate and caulk any cracks in the structure's foundation.

Tips & Warnings

• Rubber insulation is less expensive and easier to work with than fiberglass, but not the best product to be used in conjuction with heat tape since it doesn't provide any vapor barrier. Fiberglass insulation is the better insulator, though potentially irritating to the eyes, skin and lungs.
• If the house isn't in use during the coldest months, drain the plumbing system before closing the house down. A drained system is the only foolproof way to avoid a freeze-up.
• There are professionals you can call to insulate pipes of the job is a large one.
• When using electrically powered heat sources, follow the manufacturer's warnings to avoid fire hazards. Inspect any electrical implements frequently.
• Remember insulation is designed to retain the heat that is already in the pipe. It cannot add heat.
• If using fiberglass insulation be sure to wear gloves, goggles and a dust mask to protect yourself from its irritating qualities.

on 12/20/2005 Advice from a plumber: If you have a bathroom with a location that is more exposed to outside cold air than the rest of the house, you can pour about a cupful of windshield washer fluid into the sink and shower drains and leave it overnight; it has an anti-freeze effect.

on 11/22/2005 "Snow birds" who leave their homes for any length of time during the winter, or cabin owners, might want to purchase a freeze alarm or temperature monitor. These nifty devices can be programmed to phone you or a neighbor if there is a power failure or the temperature drops below a certain number of degrees.

on 12/22/2008 After removing your hoses for the winter, locate and shut off the valve supplying the outside tap. Then open the outside tap and drain all standing water from the pipt. Leave the outside tap open until the Spring, when you'll reverse the order: close the outside tap and then re-open the supply valve.
