If you live in a part of the country that gets cold, you will need to know how to keep outdoor water pipes from freezing.
Let us walk you through your options and the DIY for keeping those outdoor water pipes from freezing.
How to Keep Outdoor Water Pipes from Freezing
There are 4 things you can do to keep your outdoor water pipes from freezing. Some are easier and some are cheaper than others.
- Drain outside water lines
- Keep the outside tap dripping (Why NOT to do this Outside)
- Move the exposed pipes
- Insulate your outdoor pipes
How to keep Outdoor Water Pipes from Freezing: The Details
Drain Outside Water Lines
Draining outside water lines will remove all the water from the lines. Then there’s no water to freeze and expand inside the pipes causing them to burst. Your pipes could still become brittle over the years, being frozen and defrosting over and over again. So, while I do recommend draining your pipes, you should also think about both insulating the pipe and possibly moving the exposed pipe inside or underground.
Keep the Outside Tap Dripping (with a Warning)
Keeping your outside tap dripping just a bit means the water is running and running water doesn’t freeze easily. Problem with this advice seen on other sites, is that it might work inside your house, but it won’t work outside. It’s colder outside and the water will just start freezing into layers of ice. Eventually it will build up inside the pipe, bursting it or causing a backup.
Move the Exposed Pipes
This is the most expensive option. You would need to have some know-how or hire a plumber to physically move the pipes that are outdoors and exposed to the weather. Those pipes would then be located inside. Not anyone’s first choice, but an option worth mentioning.
Insulate Outdoor Water Pipes
Insulating your outdoor water pipes involves wrapping them up to prevent the cold from directly impacting your pipes. You can insulate them with foam insulation or pipe wrap. You can also get foam fitted to elbow and T joints to properly protect the whole pipe from freezing temps. Keep reading for our directions on how to get this done.
