Plumbing in unheated garage in Canada

[kleslie]

I have a faucet in my unheated garage that comes through the insulated wall from my laundry room. It is not a frost free faucet but there is a separate shut off inside my house that I turn off in the winter. The faucet in the garage is only used to attach a hose for summer use. I would like to extend the pipes and install a tap on the exterior of my house for easier access from outside. (see images) I plan to remove the existing tap on the wall and run PEX up through open rafters down to the wall position pictured. I don't think a frost free faucet will help me in the new location and i will STILL have to shut the water off inside the house in winter. But is there anything i need to consider in the install to avoid water being left in the pipes and freezing?

Leave the hose bib in the garage and tie off of it. in the winter drain both hose bibs. no water in pipes.

I would slope the PEX so that there are now dips and it will fully drain.

There will still be water in the high end of the pipe. Do both.

You could vent and very carefully slope to empty the pipe, but you could instead blow out the water with a compressor, each year.

THANKS ALL. Here is what I think I have heard from you. Leave the existing faucet so I can drain the vertical section of the new run to the new exterior faucet location and slope the run where possible. A new schematic below.

Looks good. Dry pipe. Extra hose bib.

Thanks OLD TIMER...but what do you mean by "dry pipe, extra hose bib"?

I mean you'll be able to completely drain the pipe and you'll have 2 hose bibs instead of one. If you knew me I am a man of few words.
