This is Tuesday evening and the concrete trucks roll on Thursday: guys I need help!
I have a trench to my new storage barn foundation, and today the builder was helping me with some service items: A 2" conduit for electric, a 3/4" for telephone, and a 1" PVC pipe for water. We were laying them in a convenient beam/trench/footing. He said "you know, PVC doesn't meet code for water, it can crack & leak under the pressure of the concrete" so I pulled it out. But I really need to get water into the same area in order to take advantage of my trench which is at the front of the building, and I wanted to have a hose bib on the opposite side of the building which would be VERY difficult to get to otherwise (rocky soil, long story).
So how to bring a water pipe into the same area with the other 2 conduits? Maybe PEX tubing poked-thru a 1 1/4" PVC pipe with a sweet 90 elbow (to protect the PEX) or something? Or just go with the PVC Sch40 pipe, but put a thick layer of sand over these conduits (they only extend 8' in before stubbing-out). I really don't want, as I said in the FRONT of the building, to bring the water pipe out of the trench on the outside of the wall and then pipe thru the walls to get to the backside (about 20' away). Note I'm in So Texas so no such thing as a frost line, though a pipe exposed to air can of course freeze down here several days of the winter.
There must be an approved way to move water thru a concrete slab???
Here's a pic showing me in the middle fiddling with tape on the current stub-outs and the trench coming-in from the right. Where the guy with the board and the Hilti leveler is on the left is where I'd wanted the hose bib. I'm happy to run pipes in the walls, but would at least like to get to where the other stub-outs are... thanks for any tips.
