Frozen Pipes in your basement and crawlspaces can be an expensive repair for the home or business owner.
Water expands inside the pipes as it freezes causing extreme pressure. This will occur regardless of plastic or metal pipe.
Unheated areas like basements garages, crawl spaces, attics and cabinets can also cause damage to the structure. Pipes that freeze more often are those that are directly exposed to the outdoors, like water faucets, swimming pool lines, sprinkler lines.
Make sure all pipes outside the house are insulated.
Check to see that pipes in unheated parts of your home (crawl and attic spaces, under cabinets) are insulated.
Check to be sure outside faucet washers are secure.
Disconnect hoses from outside faucets and use insulated faucet covers to keep them from freezing.
Keep the lid on the meter box so your meter won’t freeze.
Make sure everyone in the household knows where the main water shut-off valve is, in case a pipe breaks and it is necessary to turn the water off in a hurry. Check this valve now to make sure it is working.
Keep extra water stored up during freezing weather in case a main break or frozen pipe cuts off your water supply.
