What causes pipes to freeze
and burst?

Water in the pipes [expands] when it freezes. When it expands, most pipes in homes are usually PVC, [and] they can only handle so much. When they expand, you’re going to crack [the pipe]. PEX [cross-linked polyethylene] piping [is] what we recommend. That’s what we’ll install, because it’s more of a flexible pipe. It expands and retracts easier, so it’s less likely to break. A lot of the newer homes are being built with PEX piping.
How should residents prepare for leaving their homes vacant during cold weather?
Definitely disconnect all of the outside water hoses. Drain down the outside fixtures [and] make sure they’re all wrapped. Turn off the water to the home, and drain down the [water] system—that would be emptying the water heater, empty[ing] your water lines, run[ning] your faucets and everything until they run dry. Flush your toilets so there’s no water left in them. Keep your heat on at about 70 [degrees] just to keep it warm in there. Empty your cabinets underneath. Open your cabinets underneath your kitchen sink [and] your bathroom faucets just so the heat gets in there. … And before cold season hits, I would recommend [people] test their shut-off valve to their home and make sure it does easily turn [off so if a pipe bursts, you can turn off the water].
How are frozen pipes identified?
Logically, if they’re frozen, you’re not going to have the water flow. If [the pipes have] busted, then you’re going to have a water leak.
What should residents do if pipes freeze and burst?
Get the water turned off to your home to minimize damage. Every insurance policy is different, but that would be the first place I would start. Give [the insurance company] a call. Get some pictures if there’s damage done. Get a plumber out there.
