Love all I've learned searching this site. A world of information here!. Question , I'm replacing a shower unit with a tiled shower. After demo I found that the old drain was just 1 1/2" I plan on replacing that with 2" tapping directly into the main 4" drain under the house in the crawl space. I capped the old 1 1/2' off. how can I achive a vent ? can I just tie the old 1 1/2" into the new 2" ? or do I need to tap the new 2" directly into the vent going up the wall? Where to I tap the new 2" vent into the drain? befor the trap or after? Hope you all can figure out what I'm asking because I'm confused
thanks for any help Don
