Winter Plumbing Tips to Prevent Frozen Pipes

Even though San Jose and the Bay Area enjoy relatively mild winters, overnight temperatures can dip into the 30s and even below freezing. When that happens, unprotected pipes are at risk of freezing and bursting — which can cause thousands of dollars in water damage.

At Pacific Coast Home Services, we’ve seen firsthand how a cold snap can quickly turn into a plumbing emergency. The good news? A few preventive steps now can keep your home safe all winter long.

Why Frozen Pipes Are Dangerous

When water inside a pipe freezes, it expands. This pressure buildup can cause pipes to crack or burst, releasing gallons of water once temperatures rise again. A single burst pipe can flood floors, damage walls, and ruin belongings — not to mention create mold and mildew issues.

That’s why frozen pipe prevention is essential for San Jose homeowners, even if freezing temps only happen a few nights each year.

How to Prevent Frozen Pipes

Follow these winter plumbing tips to reduce your risk:

• Insulate Exposed Pipes
  Pipes in unheated areas like garages, attics, and crawl spaces are most vulnerable. Use foam insulation sleeves or heat tape for added protection.

• Let Faucets Drip
  On especially cold nights, let a slow trickle of water run from faucets connected to vulnerable pipes. Moving water is less likely to freeze.

• Open Cabinet Doors
  In kitchens and bathrooms, leave cabinet doors under sinks open to allow warm household air to circulate around pipes.

• Shut Off & Drain Outdoor Faucets
  Disconnect garden hoses, shut off outdoor water lines, and drain spigots to prevent ice blockages.

• Seal Drafts Around Pipes
  Use caulk or insulation to block cold air from entering near plumbing, especially around foundation walls.

Additional Winter Plumbing Tips for San Jose Homes

• Keep Your Thermostat Consistent – Avoid letting your home drop below 55°F, even when you’re away.

• Know Where Your Shut-Off Valve Is – If a pipe bursts, quickly shutting off the main water supply can minimize damage.

• Schedule a Plumbing Inspection – A professional can check for exposed or vulnerable pipes before temperatures dip.

• Consider a Whole-House Humidifier – Dry winter air can put stress on your plumbing system and your comfort.

What to Do If a Pipe Freezes

If you turn on a faucet and only a trickle comes out, you may have a frozen pipe. Here’s what to do:

1. Turn Off the Water Supply – This prevents flooding if the pipe bursts.

2. Gently Warm the Pipe – Use a hair dryer, heating pad, or warm towels. Never use open flames.

3. Call a Professional Plumber – Frozen pipes can crack without warning, so it’s best to have them inspected and repaired.
