Running Plumbing in a unheated garage.

[FishingDave]

looking at installing a hot and cold water spigot on the other side of my garage. I would have to mount the pipe on the interior wall exposed. I would like to use 3/4 pex since I am in the northeast , what would be the best way to protect it?

install shut offs and drain ports in the heated part of your garage or house and just drain the lines when you dont need the water on... and just fire it back up when you do need the water on in the winter time...
and of course just leave in on live all summer long

that would be the most simple thing to do.....

Aside from draining I'd guess you could put self regulating heat cable on it.

How often do you think the guy will use it in the wintertime??

I dont think he is coming back to look at this thread

Depends on your garage. In 30 years, my garage has never frozen (we keep water bottles in the garage). My garage part of the house with 2X6 fully insulated walls, insulated garage doors, and two common walls with the main house which provide a bit of heat to the garage.

If your garage gets cold enough to freeze water, nothing passive like insulation will protect it. Insulation only slows the flow of heat - not stops it, so without a renewable heat source (like the water being drawn regularly), the pipes and water within will eventually reach the same temperature of the garage - if it's below freezing, you'll freeze your pipes.

Even though PEX is far more resistant to freeze damage than copper and CPVC, you don't want to ever freeze it.

You can always install a heat cable like they do on old trailer parks homes....as long as you remember to
plug it in for the winter time it will work ok.... and as long as the power does not go out to that circuit
some time in the winter months it wont freeze
