Which pipe is best for cold weather?

PEX
Why PEX is the Best Pipe for Winter Weather and Beyond. In some parts of the country, cold winters are the norm, while in others, cold spurts come and go. In both cases, pipes are at risk of freezing and bursting. And when that happens, home owners become burdened with an inconvenience they don’t need.

What pipe is less likely to freeze?

PEX has the best chance of surviving low temperatures because it is so flexible. PEX is able to stretch enough to accommodate the water freezing inside of it. PEX can still burst if there’s enough pressure and swelling from frozen water.

Are PVC pipes less likely to freeze?

That’s because a flexible pipe is more likely to perform better in freezing conditions than a rigid one. So copper, PVC and CPVC are more at risk of bursting if water freezes in them than PEX is.

Can PVC be used in cold weather?

In fact, an easy-to-use product like PVC pipe becomes even more advantageous as temperatures decrease. PVC is widely used in Canada, Minnesota, and the Dakotas, so cold weather is not a limiting factor for PVC pipe projects. The design properties of PVC pipe are established at 73°F (PVC pipe’s reference temperature).

Is CPVC better for cold weather?

When you’re trying to decide when to use PVC or CPVC pipes, be sure to consider the abilities and limitations of both. PVC is best for cold-water applications and pressure and non-pressure systems while CPVC is better for hot-water applications, water supply and fire sprinklers.

How do pipes burst in cold weather?

Pipes burst because the water inside them freezes. When water freezes, it expands. The pressure between the faucet and ice is what eventually causes the pipe to crack, or in worse cases break.

Is PEX better than copper for freezing?

Copper is more likely to freeze and break. Having a degree of flexibility, PEX is able to expand if the water inside it freezes, making PEX more resistant to freeze-breakage.

How do you keep your pipes from freezing in cold weather?

Tips to help prevent pipes from freezing

1. Insulate pipes. Pipe insulation in your home’s crawl spaces and attic helps even if you live in a climate where freezing is uncommon.
2. Use heat tape or heat cables.
3. Seal leaks.
4. Secure outdoor hoses, valves and faucets.
5. Let water drip.
6. Adjust the thermostat.
7. Open cabinet doors.
