Will Pex Freeze Attic

I ve seen pex aluminum pex pipe in a floor freeze and badly.

Will pex freeze attic.

While pex does not ordinarily burst in the cold the water in the pipes can still freeze. The reason your pipes freeze and burst is simply because of the standing water in them. Cross linked polyethylene tubing better known as pex pipe has revolutionized plumbing installations in new home construction and remodeling. Depends on how often the attic is exposed to freezing temperatures.

It was stiff as a board. But pex pipes are flexible and as a result they will expand a bit during freezes making them less likely to burst. San antonio is a temperate climate and it rarely gets below freezing and i know pex is more resilient when is comes to freeze ups as the plastic tends to expand as needed. Pex does not corrode which can happen with both copper and steel pipes leading to leaks and contamination of.

My plan is to run pex thru the attic below the insulation. If you take the proper precautions you can prevent your pex pipes from freezing. Insulation will help. It is important to insulate pex pipe in an attic particularly in cold weather areas.

But what do you think and this is what a member had to say. Water inside the pipes can still freeze. Safe for potable water pex is the red and blue flexible tubing that s used to make gentle bends around obstructions in your attic and is perfect for adding water supply to hard to reach locations. No interior walls to use either.

But that doesn t mean they are freeze proof. Insulate pipes run through an attic to reduce the risk of freezing. We had some 1 pex run in an attic that due to several weird circumstances froze up solid like about 70 feet in length. Pex pipe is resistant to bursting but the fittings are not.

Need to get a hot water line from one end of the house to the other in a ranch with a concrete slab. Pex expands making it more resistant to freeze cracking than either copper or steel. I m in montana therefore it is a serious issue. I ve seen the results from a test under the floor my nephew did that one.

Existing ranch has very low ceilings 7 8 so dropping any ceilings will not work.
