pvc v abs v cast iron for dwv
I have a remodel coming up. I've had different opinions from the various plumbers and I'm up for a few more opinions from the GW plumbers. :)
We'll be removing one bathroom upstairs, and replacing it with 2 bathrooms. We will need to install 1 additional stack.
Okay, so, the new bathrooms will be over the kitchen/dining space of the main floor. I originally thought I'd want cast iron (at least for the main, new drop that will go through a corner of the LR), so help with noise dampening.
So, what I've heard so far:
Cast Iron is hard to work with and I'll pay a premium. If I just do all PVC, it will be quieter than ABS and not cost as much.
One said, to use ABS for all the horizontal work, and connect it to a cast iron drop.
One specced just ABS for all.
What say you? If you had a hall bathroom running over your kitchen, what kind of horizontal drainline would you use?
What would you use for the new drop that will be in the corner of the LR?
