As we endure one of the coldest winters in recent memory it is important to take steps to prevent your pipes from freezing. I just went through the experience, and it is not pretty. We woke up about a week ago with very little water pressure . Having lived in an old house for over 20 years I immediately knew that somewhere in the house was at least one frozen pipe, possibly more than one. We eventually found the pipe , and unfortunately it had ruptured from the expansion of the frozen water. When it thawed water just poured out of the hole in the pipe and ended up in our basement. Our pipe froze even though it was wrapped and insulated because it was too close to the outside wall. Our plumber suggested moving the pipe further inside which we are going to do when we can get him back here. Right now he is a very busy man dealing with frozen water lines and boilers.See below for suggestions on how to prevent your pipes from freezing, and what to do if they do freeze.
Preveting Frozen PIpes
- Drain water from swimming pool and water sprinkler supply lines following manufacturer's or installer's directions. Do not put antifreeze in these lines unless directed. Antifreeze is environmentally harmful, and is dangerous to humans, pets, wildlife, and landscaping.
- Remove, drain, and store hoses used outdoors. Close inside valves supplying outdoor hose bibs. Open the outside hose bibs to allow water to drain. Keep the outside valve open so that any water remaining in the pipe can expand without causing the pipe to break.
- Check around the home for other areas where water supply lines are located in unheated areas. Look in the basement, crawl space, attic, garage, and under kitchen and bathroom cabinets. Both hot and cold water pipes in these areas should be insulated.
- Consider installing specific products made to insulate water pipes like a "pipe sleeve" or installing UL-listed "heat tape," "heat cable," or similar materials on exposed water pipes. Newspaper can provide some degree of insulation and protection to exposed pipes – even ¼” of newspaper can provide significant protection in areas that usually do not have frequent or prolonged temperatures below freezing.
To Thaw Frozen Pipes
- If you turn on a faucet and only a trickle comes out, suspect a frozen pipe. Likely places for frozen pipes include against exterior walls or where your water service enters your home through the foundation.
- Keep the faucet open. As you treat the frozen pipe and the frozen area begins to melt, water will begin to flow through the frozen area. Running water through the pipe will help melt ice in the pipe.
- Apply heat to the section of pipe using an electric heating pad wrapped around the pipe, an electric hair dryer, a portable space heater (kept away from flammable materials), or by wrapping pipes with towels soaked in hot water. Do not use a blowtorch, kerosene or propane heater, charcoal stove, or other open flame device.
- Apply heat until full water pressure is restored. If you are unable to locate the frozen area, if the frozen area is not accessible, or if you can not thaw the pipe, call a licensed plumber.
- Check all other faucets in your home to find out if you have additional frozen pipes. If one pipe freezes, others may freeze, too.
