Waster discharge pipe size ? - Plumbers say tear up my new slab to up size risers

[EddieWalker]

Oh, ha, I understand now. Sorry, thought you saw something on the slab. No, thats the metal roofing but yeah they do look like long ducts with vents on there. That is a scrap piece of metal they tack onto the crate to protect the roofing. Mueller standing seam. All that rock is from East Texas Brick, think they are over in your neck of the woods.

Thanks, I've never seen it like that, but then again, all I've ever done is R panels.

East Texas Brick is both great, and sometimes very frustrating. Hope you had the great experience with them!!!
