Sleeve options for plumbing through concrete?
Fantastic forum/resource! Thanks much to the creators, and especially everyone willing to share so much of your time and knowledge!
I will be running pvc water supply and waste lines through through a concrete foundation wall and am wondering what options there are to sleeve the pipes within the concrete. The structure is a garage w/ a second story studio. The foundation wall is 8" thick concrete, rising approximately 1' above grade, with a slab poured seperately. My intention is for both the water and waste lines to enter the foundation wall approximately 1' below grade, (this is in Austin, TX - no frost line), and immediately turn 90 degrees upward within the concrete wall, to exit the concrete foundation stemwall directly within the the first floor wall framing.
Question 1. Is it okay to have pipe transitions buried within the concrete, (the 90 degree upward bends in this case, (..actually 2 contiguous 45 degree bends for the 3" waste line))?
(This allows me to keep all plumbing within the walls).
Question 2. What options are there to sleeve the pvc pipes in the concrete?
(I see reference to providing "sleeves" for all pipes through concrete in the 2003 UPC code, (the pertinent code here), but I do not know what is acceptable as a "sleeve". Given the "L", or 90 degree bend that will be entirely within the concrete, using a larger diameter pipe as the sleeve is not possible. I see job sites where it appears that pvc or copper running through concrete, (with bends/joints cast within as far as I can tell), are merely wrapped in plastic, (sometimes blue, sometimes black).
If anyone can offer advice, much appreciated.
