As the weekend nears, temperatures are going to continue to drop in the coming days.

Your KSAT Weather Authority is expecting two rounds of wintry weather for the San Antonio area from Saturday into Monday. With these below-freezing temperatures, it’s important to winterize your home ahead of time.

These cold temperatures can especially pose a threat to water pipes, both indoors and outdoors. As the ice begins to form, it can expand and possibly break your pipes, which could be costly, according to the San Antonio Water System (SAWS).

But, there are a few precautions you can take to prevent this. Here’s what you can do, according to SAWS:

  • Cold winds can speed up the freezing process. Seal up openings where cold air can reach unprotected water pipes, like faucets.
  • Foam or fiberglass insulation sleeves go a long way in keeping exposed pipes safe.
  • Leave cabinet doors open under the kitchen and bathroom sinks to allow warmer room air to circulate over the pipes.
  • If there are rooms without heating ducts, leave doors open to allow ambient heat in. Especially if the room is on the north side of the house.
  • Letting faucets drip slowly to keep water flowing through pipes is not ideal, but it can help.

Don’t worry about the pipes underground, as the temperatures won’t be cool enough to freeze them, according to SAWS.

If you do find that your house is without water during the cold weather, there are a few things to consider when trying to navigate the problem. It could be due to a frozen pipe, or another issue.

Here’s what to look for to help determine what’s causing the water outage, according to SAWS:

  • Check multiple faucets around the home. Are they all off or is it just one?
  • Check with your neighbors to see if they have water service.
  • Is your home heated? Were you away from home during the freeze?
  • Did you leave your faucets dripping? Cover your outdoor faucets?

Once the temperatures begin to warm up later on next week, make sure to check your plumbing in areas that may have been subject to freezing.

If a pipe is cracked or damaged, you’ll likely need to get it repaired.
