Avoid Frozen Pipes

Avoid Freezing Pipes


Following The Steps......

Taking the steps below before freezing temperatures arrive can help you avoid frozen pipes.

Seal cracks.

Caulk around doorframes and windows and around pipes where they enter the house to reduce incoming cold.

Wrap all pipes in unheated areas. Pipes in unheated areas such as the crawl space under the house, attic, garage and unheated basement should be wrapped to prevent freezing. Use insulating tape and wrap it over the entire length of exposed pipe. You can also use flexible molded pipe sleeves. Cover all valves, pipe fittings, etc. with insulating tape or fiberglass. We do not recommend electric heat tape for insulating water lines.

Protect outdoor pipes and faucets. In some homes, the outside faucet has its own shut-off in the basement in addition to the shut-off valve for the entire house. If you have a separate valve for outside faucets, close the valve, remove hoses, and drain the faucet. If you do not have a separate valve, wrap the outside faucets (hose bibs) in newspapers or rags covered with plastic.

Drain in-ground sprinklers. Check the manufacturer's instructions for the best way to do this.

Open cupboard doors in the kitchen and bathrooms. Water lines supplying these rooms are frequently on outside walls. Any air leaks in siding or insulation can cause these pipes to freeze. Leaving the doors open when the temperature is below freezing allows them to get more heat.

Let faucets farthest from the street or at the end of the system drip in below-freezing weather. This will add to your bill, but the amount will be nothing compared to the inconvenience and cost if the meter or pipes freeze.

Turn off all your water and drain your system if you are leaving for a long time. Turn off the main shut-off valve, then turn on all faucets, sinks tubs, showers, etc. and flush the toilets. Turn off the water heater. Then go back to the main shut-off valve and remove the plug so it can drain completely. Leaving your furnace on a low setting while you are gone helps, but it may not prevent freezing.


What should you do if a water pipe freezes?

You should make sure it never happens again! When the water freezes, it tries to expand inside the pipe. It pushes against the sides of the pipe, as well as any nearby valves, seams and faucets. The freezing action of the water is more than capable of rupturing any pipe.

Unfortunately, a water pipe may freeze even if you have taken precautions. Perhaps you lost electrical power for several hours, the temperature inside your house fell and the pipes froze. Or maybe you left on vacation, turned down the heat and weren't expecting an early blizzard. Or perhaps your heat tape quit working, and you didn't find out until you discovered none of the faucets worked.

Whatever the cause, it's important that you thaw out your pipe for two reasons:


1. You almost certainly need the water.

2. You should be at home when the pipe thaws, just in case the pipe and/or joint is ruptured.

Bear in mind that a frozen pipe doesn't leak - the water is ice. You'll discover you have a leak only after the ice melts. If you're not home, a ruptured pipe can cause a great deal of damage.

Here are some methods to thaw out frozen pipes:

CAUTION!: Before you try any of these methods, first open the faucet the frozen pipe supplies. The steam you create while heating the pipe can burst the pipe if it doesn't have an escape.

Method #1: Use electric heat tape on the pipe, and wait for it to thaw out. This is a good method to use because it slowly thaws the pipe, which means it reduces wear and tear on the pipe itself.

CAUTION!: Remember to use only heat tape certified by a nationally recognized testing laboratory for use with mobile homes. Be careful never to wrap the heat tape back over itself. This could cause the heat tape to overheat and start a fire.

Method #2: Wrap the pipe with several layers of cloth or toweling and pour hot water over the cloth / toweling. Repeat several times until the pipe is unfrozen.

Method #3: Direct a heat lamp on the pipe itself. Place the lamp at least a foot away from the pipe. Cover adjacent areas with a layer of aluminum foil so the heat does not scorch these materials. Make sure the heat lamp is on dry ground. Even better, plug it into a ground Fault Circuit Interrupter (GFCI) outlet.

CAUTION!: Do not use any direct heating method if the frozen pipe is next to a gas pipe! Call a professional for help.

Method #4: Hold a hand-operated hair dryer to the pipe, and slowly move up and down the length of the frozen section. Make sure you are standing on dry ground. Because you are working this close to water, plug the dryer into a GFCI protected outlet.

You will know the pipe is thawed out when water starts to trickle out of the open faucet. Let the water run for a while to completely clear the pipe. Then, close the faucet and check for leaks.

CAUTION!: Do not use a propane torch to thaw out frozen pipes. Do not use a propane torch even if it has a fire spreader attachment. This is not only a fire hazard, bit it's also a quick way to destroy your plastic plumbing pipes.
