Hi, I'm going to build a non-load bearing half wall in the kitchen to create a peninnsula. The wall will conceal the water and electric for the sink cabinet.
I'm wondering what the maximum size schedule 40 PVC pipe is that I can run up through the floor plate of the half-wall. If I frame the wall using
2x4s, then a 3 inch PVC pipe will practically cut the plate in half. I'd prefer to avoid building the wall out of 2x6s, just to keep the wall size down. (I'm required to use a 3 inch pipe, but nothing was said about the wall thickness.)I'm also going to put down 1/4 inch bc plywood underlayment over an existing vinyl floor. Should I put the underlayment down first, then build the wall, or put the wall right on the old flooring. (Don't want to pull up the old floor because of asbestos.)
Anyone have any input? Thanks
