After completely gutting my bathroom I have a number of questions about the original install of the vent and drain pipes and how to fix the issue.
The drain pipes and vent pipe are 1 1/2 PVC
The drain pipe to the right will be contected to a double sink with a separate vent connected to the existing stack. Do I need to change all the pipes to 2"?
about 7 feet away from the double sink will be the shower. Will I need a separate vent for the shower? If so can I connect it to the exixting stack.
can I connect a 2" drain to a 1 1/2 vent?
Any help would be greatly appreciated
