Seasonal temperature changes are a reality of life regardless of where you live. Cold weather and hot months affect plumbing in different ways, and the fluctuations can take a toll on unprotected pipes. If you don’t protect your water lines adequately, you’ll end up with burst water pipes, loss of water supply due to freezing, and faster deterioration.
At Mr. Rooter Plumbing, we are passionate about helping homeowners and businesses protect their water lines from seasonal temperature changes. That’s why we are the experts to call when you need water line replacement in your property. In this post, we share tips on how to protect water lines from seasonal temperature changes.
As winter approaches, take steps to winterize outdoor and uninsulated plumbing to protect the water lines from freezing and bursting. Remove all garden hoses from outdoor spigots, let them drain completely, and store them indoors. If your outdoor faucets aren't frost-proof, locate the indoor shut-off valve for those lines, turn it off, and open the outside spigot to drain any remaining water. This is recommended to remove trapped water that can freeze, expand, and exert tremendous pressure on your water lines.
Water lines running through unheated areas such as crawl spaces, basements, garages, and attics are more vulnerable to freezing. One of the ways you can protect these pipes is to wrap them with pre-slit foam pipe insulation and secure them with zip ties or duct tape. This is a quick and inexpensive strategy that most DIYers can take on. You can also consider using heat tape to protect water lines that are highly vulnerable to freezing. A professional plumber can help you with these tasks if you’re not comfortable handling the job yourself.
When severe drops in temperature are forecast, adjust your home habits to keep water moving and warm. Keep your thermostat set to a steady, warm temperature (ideally 55 degrees Fahrenheit or higher). Open the doors beneath your kitchen and bathroom sinks to allow the heated air in the house to circulate around the water lines in that space. During severe, prolonged sub-freezing events, run a pencil-thin stream of water from the faucet farthest away from your water meter. This may seem like wasting water, but it’s an inexpensive way to protect your water lines from freezing. Flowing water is much harder to freeze.
Seasonal temperature changes can reveal weaknesses that already exist within a plumbing system. It is important to pay attention to warning signs such as reduced water pressure, unexplained wet spots in the yard, unusual increases in water bills, and discolored water.
These symptoms may indicate a developing water line problem that should be investigated before more extensive damage occurs. Call a local plumbing service as soon as you notice signs of water line problems.
A professional plumbing inspection by a professional plumber can identify vulnerable sections of piping and detect issues that may not be visible to homeowners. Older water lines, deteriorating joints, and underground leaks can sometimes be discovered before they lead to major repairs. Routine inspections are particularly valuable for homes with aging plumbing systems or properties that have experienced previous water line issues. You’ll be able to know when it’s time for water line replacement and avoid recurring issues.
Protecting water lines requires a year-round approach that includes pipe insulation, maintaining heat circulation, and keeping an eye on vulnerable pipes. Staying ahead of seasonal plumbing risks avoids emergency repairs and gives you peace of mind. For homeowners looking for water line replacement, get in touch with Mr. Rooter Plumbing.
