: Unfortunately, I have designed and built my master bathroom with a toilet located in a place that's difficult to vent. I planned on running the drain down the joist bay the toilet is over and down a first floor interior wall. But I've realized that there is a door opening and hallway above this joist bay, thus preventing a vent from going vertically from the downgoing drain. Can I have a 2 inch vent drilled through other joists to get to another wall for venting? How close to the toilet does the vent have to be?
A two inch vent can be five feet away from the toilet in New York. ( total lenght of run from flange to vent.) As long as this is not your main stack.
