I am trying to plan the finishing of my two story addition. I live in Washington state so I am assuming this falls under the guidelines of the UPC. What I want to do is have a laundry room w/shower, sink and john on the first floor. Opposite this, there will be a kitchen with a sink. (opposite meaning on the other side of a 2X6 wall). On the second floor, I would like to have a half bath and opposite this, would be a full bath with walk-in shower. Maybe throw in a claw foot tub too. Again, opposite being on the other side of a 2X6 wall. The downstairs kitchen would be below the upstairs full bath and the downstairs laundry bath area would be below the upstairs half bath. I am trying to have a single large vent exiting the roof and also have all the drains tie into this single main stack and drain.
So I have a couple of questions to ask. ( I don't know how many total fixture 'units' this equates to)
I don't know how feasible this is, is it? Could I get away with 3" drain line or is 4" going to be what I need? Would it be better to try and vent the upper full bath separately? I am trying to stay away from exterior wall piping, but don't know if that applies to dmv stuff for codes/freezing/nail issues. If I can use a smaller vent pipe for all of this, where does the transition(s) take place? Anyhow, that is where I am at. When I called the county, all I got was get your permit and we will tell you what to do. That's nice, but I want to know what to do before I have to actually do it and am tied down with meeting permit requirements on their schedule. (I like to plan ahead for costs and etc.)
Any help would be greatly appreciated.
Thank you
