What to do if your water pipes are frozen?

If you will be going away during cold weather, leave the heat on in your home, set to a temperature no lower than 55° F. 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.

Why does my water pipe have frost on it?

Frozen pipes often have frost on them or may have a slight bulge. If the blockage is located in part of the pipe that you have access to, you will have more options for easily thawing the pipe than if the frozen portion is enclosed behind a wall.

Can a frozen water pipe lead to a faucet?

If no water comes out, or only a slight trickle escapes, then a pipe leading to the faucet is likely frozen. If one pipe is frozen, there is a chance others have frozen also. If the pipes are exposed, such as pipes under sinks, in basements or along the exterior of the house, you may be able to see the frozen portion of the pipe.

What kind of pipes are most susceptible to freezing?

But ice does build up inside pipes, blocking unfrozen water from flowing. Pipes made of copper, steel, PVC, PEX and other plastics are all susceptible to freezing, with copper being the most vulnerable to ruptures when frozen. PEX, PVC and other plastics will freeze but do not always burst.

Can a frozen water pipe be a warning sign?

This can serve as a warning sign that the pipe is frozen before you ever try to turn on the faucet. Another sign that you may have a frozen pipe on your hands is a lack of running water.

What kind of pipes are most likely to freeze?

Pipes that freeze most frequently are: Pipes that are exposed to severe cold, like outdoor hose bibs, swimming pool supply lines, and water sprinkler lines. Water supply pipes in unheated interior areas like basements and crawl spaces, attics, garages, or kitchen cabinets. Pipes that run against exterior walls that have little or no insulation.

Can a frozen faucet cause a water pipe to burst?

Technically yes, but the “wait-and-watch” method carries risk. As that ice begins to thaw, any water caught between the faucet and the ice will cause increased pressure within the pipe. That increase in pressure can lead to frozen pipes bursting.
