Any advice on stemming the plumbing before concrete pour? Would like to have running water, hot/cold, for cleaning animals and clean up on various projects. Not too worried about sewage and bathroom as shop will be close enough to house if nature calls. Was thinking about just running a buried drain line. Was thinking just tying into house water main. Any issues I should be Leary off?
You want to get water out there. If you think there is any chance you want a bathroom in there, then go ahead and run the sewer line.
It sounds like you garage is going to be pretty close to the house. In my case, my garage is your typical California 2-car detached behind the house. It's about 25' from the side man door to the closest bathroom. But, late at night, I've been known to 'water the grass'.......hey, water shortage here.....
I ran water to the side of my garage...I have a couple of spigots out there along with a sink in my BBQ grill setup. The sink just drains to the grass.
For hot water? I'd put a small water heater out there. Otherwise, your going to waste a lot of water waiting for the hot stuff to reach you. Actually, in your case, a small tankless would be ideal.
Now is the time to run conduit. PVC is cheap....don't be afraid to go bigger.
I'm assuming you want at least 60-100 amps out there. I have 50A....I never get close to that. If you do a 1.5" for power, you won't have space issues.
I'd run a 1" just for data.....Ethernet/coax/phone.
And another 1" for water....but I'd run a PEX line inside the 1". I know, over kill....but, if anyone digs, they will hit the PVC first....save having to replace the PEX if you did direct burial.
For the Water, unless you want water inside, then just run it to a spot outside the garage. For data and power, use sweeps (gradual 90's) to bring the pipe up the stem wall where you think you want your sub panel and Ethernet.
