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

While our cold is no match for yours, I had a similar problem with
this house, the upstairs feed pipes run close to the siding and would
freeze up every time it got cold. We slid the foam insulation up the
pipes from the bottom, & haven't frozen up since.
