How to Prevent Frozen Pipes in South Carolina Winters

While the Upstate of South Carolina generally enjoys mild winters, sudden freezes are not uncommon. When temperatures drop below freezing overnight, exposed pipes in your crawlspace, attic, or exterior walls can quickly freeze and burst, leading to catastrophic water damage.

1. Insulate Exposed Pipes

The most effective defense against freezing is proper insulation. Wrap any exposed pipes in unheated areas (like your garage or crawlspace) with foam pipe insulation. You can easily find these sleeves at your local hardware store in Greenville or Spartanburg.

2. Let Your Faucets Drip

Moving water is much less likely to freeze. If a hard freeze is in the forecast, turn on your faucets—both hot and cold—to a slow, steady drip. This relieves the pressure buildup inside the pipes, which is what actually causes the pipe to burst when ice forms.

3. Open Cabinet Doors

Pipes located under kitchen and bathroom sinks are vulnerable, especially if they are on an exterior wall. Open the cabinet doors to allow the warm air from your home's heating system to circulate around the plumbing.

4. Disconnect Outdoor Hoses

Before winter hits, completely disconnect and drain all garden hoses. If you leave a hose attached, water can freeze inside it and expand back into your home's plumbing system, cracking the indoor spigot. Consider installing frost-proof hose bibs for added protection.

If you suspect a pipe has frozen (your faucet won't flow), do not use an open flame to thaw it! Turn off your main water valve immediately to prevent flooding when it thaws, and call Pipedex Plumbing & Drains at 864-900-0300 for emergency assistance.
