Bathroom Addition - V2 | Page 8 | Construction and DIY projects | Forums

Interesting, so your toilet is wet vented. You've got redundancy in the wet vents though in case one is flushing the other can be used (washing machine and hand sink). My concern is that if I wet vent the toilet through the sink, if someone is using the sink, the toilet may not flush properly.

I think the toilet and sink are as good as I can get them, just have to lock down the shower vent. It may be as good as I can do. I wanted to start with the requirements and see if I could get fancy but that may be asking a bit much of my newb status.

Going to build up the filling this weekend, cut the beam trenches, and see if I can do plumbing.

Hooray! Everything finally went through the city and I spent all of yesterday and $500 getting permits.

I will do the demo on the siding tomorrow to see what I'm working with as far as re-framing goes and then just use a tarp to keep the buggers out.

Friday the concrete guy (found someone reputable) will finish the trenching and building the forms. I will then do the rough plumbing before he does the re-bar and everything else. I am going with a concrete guy ($3650) because my wife is worried about the timeline and I can't promise anything within a month, unless I quit my day job that's funding all of this.

As far as the DWV goes, I re-routed everything per your recommendations and the wetvent guidelines to simplify it to the following. This also avoids having any of the piping going through the beams, but requires the cabinet to cover up where the vent comes up in the middle of the slab. Good thing we're married to the design cause there won't be any flexibility after it's poured.

Redundancy is king in this city. The inspector came out this morning and started to tell me that I might be too close to the property line (even though this is something that a qualified plan inspector reviewed, 3 times). 30 minutes later he gave us the okay. Tearing off siding tonight and doing the rough plumbing.
