Will Pex Freeze Attic

My plan is to run pex thru the attic below the insulation.

Will pex freeze attic.

It was stiff as a board. Pex does not corrode which can happen with both copper and steel pipes leading to leaks and contamination of. I looked in the attic and noticed that all of the plumbing that once was in the slab had been replaced by pex and was now in the attic. Insulation will help.

While pex does not ordinarily burst in the cold the water in the pipes can still freeze. I ve seen pex aluminum pex pipe in a floor freeze and badly. It is important to insulate pex pipe in an attic particularly in cold weather areas. No interior walls to use either.

Pex pipe is resistant to bursting but the fittings are not. 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. I ve seen the results from a test under the floor my nephew did that one. If you take the proper precautions you can prevent your pex pipes from 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. I m in montana therefore it is a serious issue. 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. But pex pipes are flexible and as a result they will expand a bit during freezes making them less likely to burst.

Pex expands making it more resistant to freeze cracking than either copper or steel. Have seen plumbing in the attic a couple of times and insulated or not there has been or will be leaks at some point in time some winters are mild and a homeowner might get lucky. But that doesn t mean they are freeze proof. But what do you think and this is what a member had to say.

The reason your pipes freeze and burst is simply because of the standing water in them. Need to get a hot water line from one end of the house to the other in a ranch with a concrete slab. Existing ranch has very low ceilings 7 8 so dropping any ceilings will not work. Insulate pipes run through an attic to reduce the risk of freezing.

Water line would run over the top of the 2x4 bottom truss cord and i would create a tent over pipe so there was no.
