    Yah but; IF this for a house, the main sewer line ( 3" pvc) will be from 12" to 24" below the concrete. The smaller drain lines should be about 6" to 8" below bottom of concrete. you do not want the concrete poured right against the plumbing lines . It costs a little more but I always try to get people to use (sch-40) pvc,3"or' PVC) asmain sewer line . What is called (thinwall Does not hold up under concrete as well. . When building on concrete slab, Think about future plumbing troubles . I!ve BUilt some apt. buildings where I put 3" Pvc down, then ran the 3/4" water line inside of it , into where the hot water tank was going to be, Make my turn up with two 45 degree fittings. One time water froze on a unit, and it was easy to replace the shattered line. HOPE THIS helps .PLEASE RATE MY ANSWER BELOW ,tHANKS.
