1) What's the difference between schedule 40 PVC and, well, regular PVC that I might find at Lowes? I was looking online at a plumbing supply store for a
4 x 4 x 3" wye to use on my basement stack with no hub couplings. I noticed that the online store only sold schedule 40, 4" x 4" x 3" Wyes for like $40 - $50. I found the same item, probably not schedule 40 at Lowes for $8.
Do you need schedule 40 PVC for use in a 4" stack transitioning to cast iron?
2) I was planning to cut out more room than I need to put my wye into the stack and to use 4" PVC with no hub, shielded couplings to the cast iron, then cement the hubbed 4" x 4" x 3" wye to the straight PVC pipe.
Is this a good plan?
