There’s nothing like a cozy wrap to keep out winter’s chill. That’s true whether you’re talking about people or pipes. Take steps now to protect your plumbing, ahead of the season’s first hard freeze, and you’ll avoid the damage of frozen pipes.
Camas and Vancouver, Washington generally have mild winters, but there are usually times each year when the mercury drops and pipes can freeze. Here’s what you need to know to keep pipes toasty and water flowing during cold weather, and if you’re seeing this post a little too late, what to do if your pipes burst.
Locate Vulnerable Pipes
The pipes that run through unheated areas of your home are the ones most likely to freeze. This includes pipes in exterior walls and plumbing that’s on the outside of buildings.
Wrap Exposed Interior Pipes
Take a look around the attic, crawl spaces, garage and other unheated sections of the house. If you see exposed pipes, they’ll need to be protected. Wrap foam pipe insulation on any exposed plumbing. Foam insulation is inexpensive, effective and easy to install. As an added bonus, the foam may reduce the cost of heating your water since it keeps your pipes and water a few degrees warmer.
Upgrade Exterior Wall Insulation
Exterior walls need to have enough insulation to protect plumbing. If your walls lack insulation, or if the insulation wasn’t properly installed, your pipes could freeze.
Pipes to the kitchen sink often run through an exterior wall. If you see water damage, mold or mildew in that area, it’s possible the pipes froze and leaked or burst in the past. Adding more insulation to the wall may prevent future problems. As a stopgap measure, during a freeze you can leave the under-the-sink cabinet door open so warm air reaches the wall.
Drain Outdoor Spigots
It’s also important to get your outdoor plumbing ready for winter. A frozen outdoor hose can damage interior pipes. How does this happen? Water expands as it freezes. When water freezes in a hose, it may put pressure on the closed faucet and pipes. Pipes eventually burst under the stress.
Drain garden hoses, disconnect them and store them for the season. Close the interior shut-off valve to outdoor faucets. Drain the spigot and place foam insulators on each outside faucet.
Find the Water Main
Even if you take preventative measures, one of your pipes could leak or break. Know where to find the water main. If your pipes freeze, you’ll need to quickly shut off your home’s water to prevent flooding.
What if my Pipes Burst?
Pipes that freeze and then defrost have an increased chance of bursting, causing water leaks that can lead to floods that damage the structure of your home as well as your valuables. One way to avoid this hassle is to educate yourself so you are ready in the event of a plumbing emergency.
Why Pipes Burst
While it may seem counter intuitive, it is not usually the ice forming in the pipe that causes it to break. Rather, the expansion inside the pipe caused by the frozen water increases water pressure between the ice blockage and the closed faucet. Due to this pressure buildup, pipes most often burst in areas that have not yet frozen, which results in an immediate leak of icy water.
If you suspect you have a frozen pipe, don’t panic, but do take action. Call a trusted plumber immediately to report the issue. Do not attempt to thaw a frozen pipe with an open flame. This process can be dangerous and inefficient. Instead, you may be able to thaw the pipe with a hand-held hair dryer. Simply open the faucet and apply heat to the pipe slowly, beginning close to the faucet end and moving toward the frozen area. While working on your leak or burst pipe, be sure you are not standing in water. Doing so while working with electrical items can cause electrocution.
If Your Pipe Bursts
In the case of a burst pipe, do the following:
Turn off the water main shut-off valve, which is usually located at the water meter or where the main line enters your home. Leave the faucets open until your plumber has had a chance to repair the damage. If you have your own private well, be sure to use the shut off located near or on the well holding tank. Note: If you’re unsure where your shut off valves are and your pipes have not burst, do yourself a huge favor and find them now to save time in an emergency.
If your home or basement has flooded, consider whether you have any live electrical cords or outlets submerged before stepping into the standing water. If in doubt, wait for your plumber or call your local Public Works Department for assistance.
