Hey all.. I'm in CT and plan to run some 3/4 pipe to feed a new hose bibb and eventually a sink in/near my garage.. Wanted to go big since I often run sprinklers and want as much volume as possible.
My house is old and has been added on to. Plan on running pipes in a crawlspace under a newer breezeway between house and garage. Crawlspace is mainly for storage (walk out basement) and houses central air ducts. A shutoff will be installed in case but the space rarely gets cold enough to fully freeze.
So I had two questions:
- I was planning to run 3/4" PEX as will be WAY easier routing for this application, but I know copper has slightly better flow/volume. Would copper be THAT much less restrictive for this short run (maybe 10 ft max) to make it worth doing for effectively a hose and a sink?
- For the bibb, I need to exit through the front of the crawlspace through the framing then a brick facade. I have the choice to run through the plywood sheathing OR go up a little further into a joist and through the rim joist. Does code allow either option? Going through the rim joist is more work dealing w/ insulation and it will come out a bit high off the ground. Not too worried about support through plywood as the brick will hold it steady and will sleeve the pipe.
Thanks for any advice!

. Any difference in the exit point? (plywood vs rim) - def easier going through the sheathing... I don't THINK it's prohibited but worth asking if only to eliminate risk of having to make a 2nd hole through a brick wall someday.
