Is it possible to puncture PVC sewer line under slab?

[Hadrian65]

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.

Hadrian.

The only way to be entirely certain would be to drill a test hole to see exactly how thick your basement floor is.

That being said more than likely your basement slab is 4" or better.

It's easy enough to get a masonry bit and drill a hole if you're paranoid. Then just fill the hole back in.

Open The Caps And See If The Pipe Under Go Down At All. It Should Be An Indicator Of How Deep The Pipe Is.
