Even when outdoor temperatures start to drop, people can usually depend on more comfortable conditions in their homes. So, it’s all the more annoying when winter manages to creep inside and cause trouble. A particularly frustrating problem is when the pipes of your plumbing system freeze up. Dealing with frozen pipes can range from inconvenient to a widespread, costly mess.
Many people prefer to call their plumber to handle frozen pipes, and that’s never a bad idea. But you can also thaw them out yourself with just a few items from around the house. To help you resolve this irritating plumbing problem, here’s a step-by-step guide for thawing frozen pipes.
Step 1: Locate the Frozen Pipes
The first and sometimes most difficult step is locating the frozen pipes. Running all your faucets may help you narrow down likely locations. If one faucet isn’t running, you can follow those specific plumbing lines and hopefully locate the frozen pipes. The pipes themselves may not be obvious to spot unless ice is visibly covering them.
Instead, you can move your hands along the plumbing until you pick up on a sudden drop in temperature. Once you’ve found where the plumbing is coldest, you’ve likely found the frozen pipes.
This method won’t work if every faucet isn’t running. You’ll want to check the main water line at this point as it’s the source of your home’s water supply. Each set of plumbing lines will eventually lead back to the water main. You’ll probably find yours in the basement or crawlspace. But if your home doesn’t have either of those things, try near the water heater or in the garage next. If you still can’t find it, locate your home’s water meter on an exterior wall, as the main line can often be found on the other side.
Step 2: Flush Your Plumbing System
After verifying the pipes are frozen, shut off the main water supply. You can’t thaw the pipes with ice cold water on the inside, so you’ll also want to run every faucet if you haven’t already. This flushes the remaining water from the plumbing. Toilets will need to be flushed as well.
Once the plumbing is drained of water, it’s time to begin the thawing process. Gather a few things before you begin:
- A source of heat: This could be a hair dryer, a heat lamp, a heating pad or even just a bucket of hot water.
- Some towels or cloths: Spare rags can help apply heat onto the frozen pipes. Or, if the pipes have burst, they can help you mop up.
Step 3: Use Slow, Even Heat
You don’t want to heat up the pipes too quickly, as that can damage your plumbing. Depending on your heat source, prioritize the edges of the frozen area. This keeps the process slow and steady. Also, do your best to heat the pipes closest to the nearest kitchen or bathroom faucet. If any steam or water is produced by the heating process, it’ll flow in that direction.
Carefully inch your way along the pipe, heating sections a bit at a time. Some homeowners choose to turn up their thermostats, using the warmer air to evenly thaw all the pipes at once. As long as this is done slowly, it shouldn’t be a problem. With a bit of luck, you’ll have successfully thawed your frozen pipes. But there’s one more step to complete.
Step 4: Reopen the Water Main and Check for Leaks
Head back to the water main. Open the supply line, but only a little. This delivers enough water to check for leaks without causing a mess. A leak should be fairly obvious to find, and you should shut the water main off again if you do. At this point, it’s usually best to call for a plumber. They’ll have the tools and experience to repair the damage, including replacing the broken pipes.
If there’s not a leak, however, you can open the main water line the rest of the way before getting to all the faucets.
Frozen Pipe FAQ
Sometimes thawing out frozen pipes is a little more difficult. Let’s review some of the most likely complications and what you can do to work around them.
How long should it take to drain a frozen pipe?
30 to 45 minutes is a good average, with more serious icing requiring added time. Don’t try to speed the process up with more heat as this could damage the plumbing and make the problem worse.
What should I do if a pipe bursts or leaks?
Without the proper tools and experience, it’s best to call a trusted plumber in Austin. Not only can they repair things more quickly and effectively, but they’ll have a better chance of noticing if other plumbing problems are nearby.
How can I reach frozen pipes if they’re behind walls?
A lot of your plumbing is installed behind walls, making them somewhat tricky to thaw out. Heating the nearest accessible area might work, or you could try heating the section of the wall closest to the frozen pipes. Heat lamps and your thermostat will be your best options. If these don’t work, you may have to remove a section of the wall to get close enough to start the thawing process.
How to Prevent Pipes from Freezing
The ideal way to thaw frozen pipes is to prevent them from icing over in the first place. Pipes closest to unheated spaces or the outer wall of your home are at the most risk. It’s not impossible for other pipes to freeze over, but this is less common as they’re usually close to insulation or between the floors of your home where it’s [[warm|warmer|not as cold|90].
Here are a few things you can do to minimize the risk of pipes freezing:
- Keep your home warmer than 55 degrees: You’ll almost certainly prefer warmer temperatures than this, but 55 degrees or more is a good rule of thumb if you won’t be home.
- Insulate your pipes with electric pipe heat tape or insulation wrap: These materials keep pipes warmer, significantly reducing the risk they’ll freeze over.
- Keep a small amount of water trickling through the plumbing: Flowing water is much more difficult to freeze than still water. You’ll want to do this with every faucet, and your water bill shouldn’t spike.
- Open cabinets and other doors to ensure even heat distribution: Closed doors and cabinets are quite good at keeping heat out. Leave these open in serious cold to keep warm air flowing freely.
If you follow these steps, you’ll either stop pipes from freezing or have a straightforward way of thawing them out. If you’d rather leave the work to a professional, call your nearest plumber in Austin. They’ll make sure your plumbing is taken care of safely.
