Hi. I am an owner-builder who has done all the framing, installing windows/doors, roofing, siding and now am tackling plumbing. I had hired a plumber but he ran off with my deposit so now while I chase him in small claims court I am trying to figure out my DWV layout to apply for a plumbing permit. I am located in British Columbia and the lower mainland (not Vancouver). If someone would be so kind to review my layout for meeting code that would be amazing. ABS is fairly cheap so I am looking at more ease of install than necessarily using the least amount of of material.
