Whether you’re flying the coop for the whole winter or taking a long holiday vacation, it’s important to winterize your vacant home before you leave. If you don’t take precautions, you could end up coming home to some serious and expensive damage. Follow the checklist below to help avoid any unwanted surprises when you return.
Turn off the water supply
The most important thing you need to do, especially if you’re leaving for the entire winter, is shut off your water supply. Leaving the water on when the lines aren’t going to be used can lead to a leak or burst pipe, which can cause a lot of damage. Shut your water off at the main valve, usually located outside. If you have a well, simply shut the breaker to the pump.
If you’re not going to shut off the water supply, you should leave some water running through the pipes. Turn on the fixtures closest to where water enters the house and at the farthest point indoors, like an upstairs bathroom, so there’s a steady trickle. The water needs to be constantly flowing to avoid a problem.
Drain the waterlines
When you shut off your water, you don’t want any water to remain in your pipes or they could freeze and expand. So drain your waterlines by opening all the faucets in your home and flushing all the toilets. Allow the water to run until it becomes a slow drip. After the toilets have drained their tanks, flush them one more time to empty the bowls. If your water supply comes from a well, drain the pressure tank.
If you’re going to be shutting off the pilot light to your water heater, you will want to drain it as well. Go here for a helpful tutorial on how to drain a water heater.
Insulate pipes
Whether or not you turn off your water, it’s a good idea to wrap insulation around your pipes, such as the ones leading to and from your water heater, any pipes exposed outdoors or in a crawl space, etc. This will give you added protection from bursting pipes during a deep freeze.
