ABS vs PVC for in house DWV

[WandaCC]

Hi,

I am new at this so pardon me if this is something very silly. I am working on a project and a master plumber told me that PVC drain pipes are not allowed for in house (above ground) use in Ontario. I went over the code again and again and I did not find anything stopping me from installing PVC pipes for DWV. I just want to make sure that I am not missing anything. The doubt arises because I have only seen ABS being used for above ground applications over here. Any help/info will be greatly appreciated. Thanks.

If you're working with ABS or PVC for DWV systems, checking local code requirements can save you from headaches down the road. Some areas strongly prefer one over the other, and inspectors can be strict. Speaking of inspectors, I've seen issues flagged during building inspections Perth because the wrong type of pipe was used or transitions weren’t done correctly. Always double-check what's allowed before committing to a material.
