Blog How to Winterize Your Plumbing System Before the Cold Hits May 02, 2025

As winter's chill begins to creep in, the last thing homeowners need is the stress of dealing with a plumbing system that hasn’t been properly winterized. At Plumbersmith, we understand the importance of protecting your home from the ravages of cold weather. Winterizing your plumbing system not only saves money on repairs but also ensures a smooth functioning system all season long. Let’s dive into some effective strategies to safeguard your plumbing before the frost sets in.

The first step in winterizing your plumbing involves examining your pipes for any vulnerabilities. Pipes located in unheated areas such as basements, attics, and garages are especially prone to freezing. Wrapping these pipes with pipe insulation or heat tape can go a long way in preventing cold air from seeping in and causing blockages or bursts. Slipping pipe sleeves over sections of pipe is an affordable and efficient way to retain heat, reducing the risk of freezing temperatures inflicting damage.

Moving to the exterior of your home, it’s important to disconnect and store garden hoses. Leaving hoses attached can cause water to back up in the pipes and faucets, which may freeze, expand, and eventually cause pipes to rupture. Once hoses are removed, cover outdoor faucets with insulated faucet covers. This simple but effective barrier against the cold is a crucial line of defense.

Next, it is essential to drain and shut off water to any outdoor irrigation systems. By purging these systems of water and turning off their supply, you greatly reduce the risk of freeze-related damages. If you have a sprinkler system, consider hiring a professional to blow out the lines to ensure they're thoroughly cleared.

For homeowners in traditionally warm climates where temperatures occasionally dip, leaving your faucets on a slow drip can prevent internal freezing. This tactic works by relieving pressure buildup inside pipes, which minimizes the chance of them bursting. Opening cabinet doors under sinks allows warm air to circulate around plumbing, keeping them warmer during extremely cold conditions.

Inside the home, check for leaks in your plumbing system. Even minor leaks can exacerbate winter problems, so it’s best to fix any identified issues before temperatures drop too low. Inspect and replace any worn-out washers or damaged fixtures, prioritizing any repairs that could worsen in colder weather.

If your home is equipped with a water heater, it's prudent to lower its settings to a moderate 120 degrees Fahrenheit to conserve energy while still ensuring pipes won’t freeze. It may also help to insulate your water heater and the hot water pipes, which not only saves on energy costs but also maintains your home’s overall efficiency.

Finally, as an emergency preparedness measure, know where the main shut-off valve for your water supply is located. In the event of a pipe bursting, you can quickly halt the water flow, mitigating damage and reducing costs.

By implementing these proactive steps, your plumbing system can weather the winter months confidently. As always, if you encounter any issues or have specific concerns, Plumbersmith's expert team is ready to provide assistance.
