Advice needed - Use ABS or PVC for waste pipe under our basemenst slab?
Hello DIY'ers - would like to turn to you for a third-party opinion here.
We're in the process of lowering our basement floor, and has uncovered some old clay piping that was installed 60+ years ago -- as you can imagine, it's cracked and caving in at spots, so we need to replace.
As you can imagine, I've had many plumbers come in and give me their opinion on what materials to use, and as a result, their prices seem to swing wildly.
Basically - I have one plumber telling me we should use ABS 4" all the way, from the cast iron stack to the city connection, while another tells me ABS is way overkill and that PVC is the material of choice. The price difference between ABS and PVC is quite large. We also need to snap off part of the stack and replace it -- should we use ABS? or PVC?
From the research I've done, I'm seeing that PVC is typically what's used for the waste piping, while ABS is used for floor and toilet drains.
The question is, which one is right? Am I really "better off" using ABS (the plumber tells me is a much better product, it's strong and will not "crack" over time - something PVC will.
