Rough plumbing....

[FrankInWIS]

Well, it's been a LONG winter in Wisconsin.  Building Inspector came in January and I had a major stall with a concern he had regarding my trusses.  I let it ride for a while, made a few improvements, and got him the drawings I promised....but my son had lost.  All is good now, we passed.
I built the garage / storage.... that is a bit more like a garage / apartment. Upper is real nice, numorous dormers, many windows.  It's not a residence though, so I still have to tred lightly. 
I got a stove in, refridgerator, etc. My son's are complaining it's getting too comfortable.

Now for a little plumbing.  For the summer I'll live with 150 of garden hose from the shallow well.  I want to put a shower in the garage, a sink, and maybe a bit more. nothing through the slab though, all above the slab. 

???What's easy for runing hot and cold supply lines?  PVC for the waste and venting of course.  Wonder what type of tubing and connectors I should be going with.  Non of this plumbing will ever be permanent, that comes later when the upstairs becomes an extension of the house to be attached next door when that is built.  Thanks.

For the water supply system buy a PEX tool. Run PEX tubing. Red for hot, blue for cold if you desire. You can even reuse all the fittings later. Probably reuse some of the tubing too. Just avoid putting joints within the walls anywhere. There's a minimal number of fitting needed compared to copper or CPVC, no gluing, no soldering.

PVC or ABS for the DWV.

I used polybuteline water lines and crimp fittings for the "shed", same as I used for the house.  No doubt you have a similar product in the USA.  Not much more expensive but much more reliable and just as easy to install as a more temorary solution.  It has also worked out well because like many owner builders, I spent a lot longer living in my shed than I ever expected I would.

Good Luck
