Is it possible to puncture PVC sewer line under slab?
I will shortly be finishing my basement. I intend to fasten the wall base plates to the slab with load-powered nails. The sanitary sewer line does run beneath the portion of the basement I will be working on. I am uncertain how deep the sewer lines run under the slab, and the nails I bought will penetrate no more than 1" Should I be concerned about putting a nail through one of these lines?
There are two places were the lines connect with the surface of the slab, both with a kind of PVC screw top outlet that is flush with the floor. Our builder (4 years ago) said something about these being back-up protectors. Should I be more concered around these fixtures if I am nailing?
Thank you for any help with these questions.
