Hello,
I am new to this forum and have been searching for days now for an answer to my problem online. Short of having a plumber come out to just give me the answer I need I thought I would try this. I understand the concepts of plumbing as far as p-traps and such but I am totally confused on the concept of venting, atleast in my situation. I do not currently have any pictures because i just started ripping out the drywall and noticed that my first floor powder room and laundry room does not have a vent from each fixture (i.e.--toilet, sink, and washing machine). These items are sitting on concrete slab. Now I know that the main stack is vented which sits in the wall behind the sink and toilet on the first floor and runs straight up behind the bathroom on the second floor.
Here's my problem. I am going to relocate the drain for the washing machine and am quite unsure how to add a vent. There is no easy way to tie into the existing vent on top of the stack from the side of the house I am working from due to a lower roof. Can I add a second vent through the lower roof and tie the first floor sink and washing machine to this in the lower roof attic or will this cause flow problems due to the main stack being vented? I live in a city where the UPC is law.
