FREEZING & BURSTING PIPES
The winter months sure can bring some cold temperatures. When temperatures drop, one major issue that could come up is a frozen water pipe. Learn why frozen pipes can burst, things to look for and how to avoid freezing pipes.
Why Do Frozen Pipes Burst?
Contrary to popular belief, it’s not the ice expanding in the pipe that causes the burst, but it’s the pressure that builds up between the closed faucet and the blockage. Ice doesn’t always expand & break the pipe itself, sometimes ice grows lengthwise which can put more and more pressure on any water not yet frozen. Because liquid doesn’t compress very well, the force is redirected against any weaknesses in the pipe and ultimately results in a break or burst.
Signs of Frozen Pipes
STRANGE SMELLS – if you have an odd smell coming from a faucet or drain it could mean you have a blockage or frozen pipe. If the pipe is partially or completely blocked, the only way the odor can escape is back up in the direction of your property.
NO WATER OR VERY LITTLE WATER – if you turn on a faucet and only a slight trickle or no water at all comes out, the water pipe leading to the faucet may be frozen.
THERE IS FROST ON THE PIPE – you may be able to see frost that has accumulated on the exterior of the pipe, which can serve as a warning sign that the pipe is frozen.
THE TEMPERATURE IS RIGHT – pipes cannot freeze if it is not cold enough outside for them to do so. If you suspect a blockage in your pipes, but the temperature isn’t quite cold enough to freeze things, you may be at risk for other plumbing issues.
What To Do If You Suspect A Frozen Pipe
If you open a faucet and no water comes out, don’t take any chances and call in one of the professionals at Hunter Plumbing, Heating & Excavating Inc.
If a water pipe has burst you should:
Switch off the water supply at the main shut-off valve, & leave the faucet open until all repairs have been completed
Do not attempt to thaw a frozen pipe with an open flame, blow torch or heat lamp as this could cause potential damage to the tube
You might be able to thaw a pipe with a handheld hair dryer. Work closely at the faucet’s end with the valve open and continue toward the frozen section. Remember to never use any electrical appliances while standing in water, as you are at risk of being electrocuted.
Preventative Solutions
INSULATION – wall insulation or foam pipe insulation is the most effective way to reduce the possibility of frozen pipes.
LET IT DRIP – letting a faucet drip during extreme cold weather can help prevent a pipe from bursting. It provides relief from excessive pressure that can build up between the faucet and the ice blockage.
