Plumbing is especially susceptible to cold weather and freezing. Burst pipes from freezing can cause some of the most expensive repairs in the home. So let's go over some of the basics to make you have them covered.
- Insulate Exposed Piping
If you have any exposed water or drain piping at all in uninsulated spaces such as in a crawlspace, attic, outside walls, etc., make sure to insulate them with foam insulation at a minimum. Ideally you should wrap them with electrical heating tape first, then insulate them.

- Exterior Faucets
Known as hose bibbs or sill-cocks, the exterior faucet needs to have its water supply turned off inside the house, and you also need to drain water from it by opening up the exterior faucet. You may also want to consider an insulated cover for the hose bibb. And remember to disconnect your garden hoses from the sill cocks or outside faucets and drain them if you store them outside.
If you are shutting down a property for several months you should always shut off the water supply and drain the plumbing system. If a leak were to occur without occupancy, the damage could be catastrophic. See How to Drain Your Home's Plumbing System.
