I know it sounds bad, but here's the deal. I have a 3 inch WC drain individual vented with 2-in pipe. The plumbers overdrilled a 2x4 stud to get the 2 inch through it. Well since it's a bearing wall at that point, it turns out this is creating a problem. A 1.5 inch pipe could pass the stud without drilling more than 60% and I believe this is acceptable if we double the stud.
So given that a 1.5" vent is large enough to vent the WC, can I replace just the section passing the stud with 1.5", or do I need to replace it all the way from that point down to the drain?
Thanks DIY
