Destroying stem wall for plumbing?
Destroying stem wall for plumbing?
(OP)
Is it "standard practice"-as my contractor claims-to allow the plumber to break pieces out of the stem-wall to accomodate the underslab plumbing?

What concerns me--besides seeming like poor practice--is how close this is to one of the anchor bolts.

How is the plumber planning to repair your wall? If the anchor bolts are compromised, epoxy injection of the cracks may be a solution. Of course, the other option is to demo. the affected area and repour it at the plumbers expense.

in your picture i also noticed what looks like copper water lines laying over the drain line. this is also bad. backfilling will bend and maybe destroy those lines. plus, may deflect the drain line down and create a low spot in the drain line; this is also bad. besides, its a code violation to cross plumbing lines one on top of the other like that. this is your second post about this contractor and you are still in the ground. sound like you should change builders asap. good luck.

The black pipe looks like ABS which is only used here as a DWV (drain waste vent) pipe. Yet your photo shows a hose bib connected to the pipe, which implies a pressure pipe. Can you explain?
If it’s a DWV then there should be a cleanout at the bottom as well.
Also there appears to be large size bare copper wire in the photo. This is generally only used for grounds and one is enough.
The white pipe appears to be CPVC water pipe. This should not be crossing the DWV pipe.
Why could the contractor not simply have the 45 bend at the top of the concrete wall? This would eliminate the need for chipping out the concrete?
Is this an interior or exterior wall?

Second, that is the drain pipe for the kitchen sink (don't know why they have a hose bib on there right now).
Third, what you are taking as copper wire is copper supply line (Cerro Brand 1" to be exact). Presumably for the kitchen sink and drinking water system.
The 45º bend can't be above the stem wall since when the slab is poured, the pipes need to not protrude from where the framing will bolt on to the stem wall. (i.e. the plumbing will be completely in the wall).
I must say, I appreciate the feedback here. Keep it coming.

With these ways and where no doubling ceiling is available, the want of invisible mechanical services cause the things to become cramped. Partition walls I have seen truly distroyed by the later setting there of the pipes, and where correct it is the gypsum or mortar infilling and facing that restores integrity enough. The alternatives in the past and with such practices were not much, and only when a wall had some structural bearing the works' directors were more attentive to the ways. But to distroy to later perfect is a practice that has been ongoing for millenniums in the realm of construction. Likely the gremial division has something to do to it, since all would be wanting independence, which is not truly feasibe when all is to be integrated.
