A pipe that freezes and then bursts can cause a tremendous amount of damage, especially if it’s not discovered and rectified in a timely manner. Not only will the interior of your home be soaked, wallboard reduced to mush, and your lower floors turned into wading pools, but if that water then freezes and thaws, you’ll come home to buckled flooring, destroyed furniture, and a whopping repair bill.
Whether you’re winterizing your own home before a trip or preparing a mountain vacation home, it’s always a good idea to do everything you can to prevent frozen pipes.
Snowbirds fleeing the frozen north may want to take extra precautions to winterize their home, such as draining the whole interior water supply system by shutting off the water main and turning on all faucets and flushing the toilets. A pipe burst due to freezing is highly unlikely in this situation, even if the furnace fails.
