I am working on a basement bathroom and need some help verifying that the existing shower and toilet drains are ABS or PVC. I know that should be easy but there are a few nuances and I want to be very sure before I continue.
- Toilet drain - pretty positive this is ABS; looks like there was PVC around it, but that shouldn't matter. Since I'll be gluing a flange on the inside, I should use ABS and ABS glue.
- Shower drain - the picture shows the p-trap. The edge of the trap looks black, but there are some polished grey/white areas shown towards the bottom of the p-trap. I'm guessing it's ABS and I'm overthinking the grey/white areas.
