As the seasons change, your home’s plumbing system, especially an older one, can face various challenges. Cold weather can lead to frozen pipes, while the demands of summer can stress outdated systems. Preparing an older plumbing system for these changes can help you avoid costly repairs and ensure smooth functionality year-round. Here are some tips and tricks to protect and maintain your plumbing system as the seasons shift.

1. Insulate Pipes for Colder Weather

One of the biggest threats to plumbing in winter is frozen pipes. When water freezes, it expands, which can cause pipes to crack or burst, leading to water damage and expensive repairs. Older plumbing systems are particularly vulnerable, as they often lack modern insulation.

To prepare, start by wrapping exposed pipes in insulation sleeves or foam insulation. Focus on pipes in unheated spaces, such as basements, crawl spaces, and garages. Pipe insulation can significantly reduce the risk of freezing and is a simple DIY solution that can make a big difference. For added protection, consider adding heating cables to pipes in extremely cold areas.

2. Seal Cracks and Openings

Inspect your home for cracks, holes, or openings around pipes that lead outside, as cold air can infiltrate these areas and freeze pipes. Seal these gaps with caulk or expanding foam to prevent drafts and keep the warmth inside. This step is especially important for homes with older plumbing, as these systems are more prone to temperature-related issues. Sealing drafts not only protects your plumbing but also improves overall energy efficiency.

3. Test and Drain Outdoor Faucets

During the colder months, any outdoor plumbing needs special attention. Outdoor faucets, also known as hose bibs, are especially susceptible to freezing. First, disconnect any hoses from the faucets, as water left inside the hose can freeze and expand back into the faucet. Next, turn off the water supply to outdoor faucets if possible, and drain any remaining water in the pipes. This precaution can prevent ice formation and keep your plumbing intact through winter.

4. Inspect Your Water Heater

A well-functioning water heater is crucial as temperatures drop. With older plumbing systems, water heaters can be less efficient, so regular maintenance is essential. Flush your water heater to remove sediment buildup, which can reduce efficiency. Check the temperature setting and consider lowering it to 120°F, which saves energy while keeping water warm enough for comfort. For extra energy savings and to reduce heat loss, wrap the water heater with an insulation blanket, especially if it’s located in a cold area like a garage or basement.

5. Check for Leaks

Older plumbing systems are prone to leaks, and small leaks can worsen with temperature fluctuations. Inspect visible pipes and joints for any signs of dripping, corrosion, or water stains. Addressing leaks before cold weather hits can prevent them from expanding into larger problems. Keep an eye on your water bill as well, as a sudden increase may indicate hidden leaks. If you notice any signs of leaks, calling a professional plumbing service can save you from more extensive repairs down the line.

6. Prepare Your Sump Pump

If your home has a sump pump, ensure it’s in good working condition before heavy spring rains or snowmelt. Older sump pumps, in particular, can become clogged or lose efficiency over time. Clean the sump pit, test the pump by pouring water into it, and check the discharge pipe to ensure water can flow away from your foundation. This preparation can help prevent basement flooding and protect your home from water damage.

7. Let Faucets Drip During Freezing Weather

For homes with especially cold winters, letting faucets drip slightly can prevent pipes from freezing. This keeps water moving through the system and reduces pressure if pipes do freeze, which can prevent them from bursting. While this does use a small amount of water, it’s a preventive measure that’s far less costly than dealing with burst pipes. Focus on faucets that are on exterior walls or in unheated spaces, as they are more susceptible to freezing.

Preparing an older plumbing system for seasonal changes requires attention to both minor details and regular maintenance. By insulating pipes, sealing drafts, checking your water heater, and addressing leaks, you can help your plumbing system withstand temperature changes and prevent costly repairs. For homes with older plumbing, these preventive measures are especially important to maintain efficiency and avoid potential issues. Taking the time to protect your pipes and plumbing now will pay off in reliable performance throughout the seasons, keeping your home safe and your water flowing smoothly.
