Default Pex in cold weather.

PVC water line in up north cabin burst. Will PEX hold up better in cold weather?

I have heard that it will, but I have no personal experience to prove or disprove that.

PEX can usually withstand freezing.

How to prevent water from freezing inside the PEX pipes?

you could go with a type of plastic pipe called wirsbo it will expand three times it normal size without bursting and then return to its normal size once thawed price is competitive with pex just cant be in direct sun light and normal rings and crimpers will work

If I am not mistaken, it is the connectors that usually end up bursting when dealing with PEX. I have no personal knowledge of this, but many plumbers in the mountains have mentioned it to me.

There are different 'types' of Pex tubing (A, B, C). Pex A (wirsbo) will expand as stated earlier. I'm in Oregon and we use Wirsbo for most residential applications and I've installed up to 2" Wirsbo in really cold weather, it's harder to work with and it takes longer to shrink back on the fittings. Using a torch lightly on the rings will shrink them quickly so you can turn the water on sooner. I've yet to see or hear of Wirsbo freeze breaking but I'm sure it can happen under extreme conditions. The fittings and collars(rings) are the weakest link in the Wirsbo System. Rehau is a great product as well, expensive though.

Also, I used to work for a small resy company who used "RTI" or "Zurn Pex". It's a quick to install system but we had several issues with the crimp rings. Sometimes the broke or didn't crimp right. Not to mention they are "insert fittings" and neck down the inside diameter of the pipe, creating a large restriction (friction loss). How they are legal...I can only assume they lobbied hard...$$$

I use wirsbo all the time I actually had a house freeze this year with it and the only leak was where the home owner used a torch to try and thaw the pipe they actually melted it, otherwise house was froze solid for a few days no wirsbo breaks

All pex pipes have a better expansion ratio then metal pipes. Of course Wirsbo is probably the best choice due to the fact that the product installation is based on contracting back to original shape. This is due to Wirsbo being a cross linked polyethylene product. As others have stated though, the fittings will definitely freeze and break in certain conditions. You should insulate the lines or where the weather is extremely cold, heat trace any exposed lines.

Pex will withstand freezing better than most......Just dont put your fittings close together......if you do the pex will not have enough room to expand and will/could fail.
