Hi.
I live in Minneapolis and just bought a new house.
On the first cold winter night, no water came out of the upstairs
bathroom cold faucet.
The pipe, I discovered, is really close to an outside wall.
I was wondering if replacing the copper pipe with pex pipe would be a
good solution.

thanks a lot,

William

It won't keep it from freezing, but the pex won't break when it does.
