Simple Steps to Protect Your Home from Costly Pipe Damage
As temperatures drop across the Bay Area, your home’s plumbing system faces its biggest annual challenge. A single frozen pipe can burst and cause thousands of dollars in water damage, making winter preparation one of the smartest investments you can make as a homeowner.

Why Winter Threatens Your Plumbing System
Water expands by roughly 9% when it freezes, creating tremendous pressure inside your pipes. This expansion can crack even the strongest copper or PVC pipes, especially those located in unheated areas like basements, attics, crawl spaces, and garages. The most vulnerable spots are typically outdoor faucets, pipes along exterior walls, and any plumbing in uninsulated areas of your home.
Protect Your Outdoor Plumbing
Your outdoor plumbing takes the biggest hit during winter months. Start by disconnecting all garden hoses and draining them completely before storing them indoors. Water trapped in connected hoses can freeze and expand back into your home’s pipes, causing interior damage.
Next, shut off the water supply to outdoor spigots using the indoor shutoff valve, then open the outdoor faucet to drain any remaining water. If you don’t have frost-proof outdoor faucets, install insulated covers over each spigot for added protection.
For homes with underground sprinkler systems, drain all water from the lines and backflow prevention assembly, then wrap the assembly with foam insulation.
Insulate Vulnerable Indoor Pipes
Pipes in unheated areas need protection before the first freeze. Use foam pipe insulation sleeves to wrap exposed pipes in basements, attics, garages, and crawl spaces. This inexpensive material is available at most hardware stores and can be installed without professional help.
Pay special attention to pipes near exterior walls, where cold air penetration is most likely. For extremely vulnerable areas, consider using heat tape or pipe warmers that automatically activate when temperatures approach freezing.
Maintain Consistent Indoor Temperatures
Keep your home’s thermostat set to at least 55°F, even when you’re away for extended periods. This minimum temperature helps prevent pipes from freezing while balancing energy costs. During severe cold snaps, consider raising the temperature a few degrees higher.
Open cabinet doors under sinks, especially those located against exterior walls. This allows warm air from your home to circulate around the pipes and prevents cold pockets from forming.
Prepare Your Water Heater for Extra Demand
Cold weather puts additional strain on your water heater as it works harder to maintain hot water temperatures. Schedule a professional inspection to check for leaks, unusual noises, or signs of wear. Flush the tank to remove sediment buildup that can reduce efficiency and lead to overheating.
Consider wrapping older water heaters with an insulating blanket and insulating the first few feet of hot water pipes leaving the tank. Set your thermostat to 120°F to balance comfort with energy efficiency.
Clean Gutters and Downspouts
Clogged gutters can create ice dams that back water into your home and affect your plumbing system. Remove all debris from gutters and downspouts before winter arrives, ensuring proper drainage away from your foundation.
Know Your Emergency Procedures
Locate your main water shutoff valve and ensure it operates smoothly. Most are located near the water meter, in the basement, or in a utility area. Test the valve by turning it gently in both directions, and apply penetrating oil if it’s stiff.
During extreme cold periods, let faucets drip slightly, especially those farthest from where water enters your home. Moving water is much less likely to freeze than standing water.
When Cold Weather Strikes
If temperatures drop to 20°F or below, take extra precautions by covering crawl space vents temporarily and opening cabinet doors under sinks. Remember to uncover vents once temperatures rise.
Should you discover frozen pipes, never use open flames or electrical appliances like hair dryers to thaw them. Instead, warm towels or blankets in the dryer and wrap them around the frozen section, repeating until water flows.
