I'm hoping someone will see this if I bump it back to page one.

Hi gents - I would be grateful if you could take a look at . The black is existing DWV, and blue is proposed new DWV. Err, I did exclude the 2nd floor details including its vent which I think is 2". I am adding a 1/2 bath on the first floor. If space permits I would like to add a shower too, but the space is very small. The main drain in the house wraps around the 3 outer walls of the basement. Overall I plan to upgrade the main size to 3" from 2", and add a 2" vent off the back of the new lavatory with a 2" wet tie-in to the WC. Our county adopted the "2006 National Standard Plumbing Code". These are my questions: * does my venting seem to be sufficient? * the new 2" vent (from back of lavatory) will run horizontal in the ceiling about 4' before running to the roof. That's ok right? * is a 1/2" per foot slope adequate? * does the wet vent look appropriate for the WC? * I would run the wet vent with a 3"-2" wye, or should that rather be a sanitary Tee? How is that normally installed? * is it OK that the new kitchen sink is placed after the vent? Thanks for your thoughts - Kent

Graywings, 1929Spanish, joaniepoani - Points taken. Given all the other input, a full bath does not seem to be that needed. Since there is no other place to put a bath on the main floor, it looks like the half bath off the back porch is where it will stay. Spanish - The china cabinet will have to go, but I am moving it to the living room in some form or another. It never has stored china in it anyway. kashka_kat - We've lived here 17 years and agree the house needs to retain elements of its period; however, previous owners destroyed all original trim and features. The baseboards are even gone, and 100 years of earthquakes have destroyed the plaster. Since I must replace all wiring and plumbing and HVAC, we are gutting room by room and trying to find a balance between the modern lifestyle and period design and architecture. I have been working on the house now for four years. All that remains to remodel is the main floor and the upstairs bath. We love the house as is but the current kitchen is a nightmare. Beverly - Thanks. Using the existing kitchen footprint for a plan is what I have been working on for two years now, but we've reached a stalemate (my wife and I). Your plan is a variation of what we have gone over and over and over and over.... :) tracie_erin - We've tried to fit an island but the space is too small and opening up the entire back half of the house is not something we want to do. We both agree the kitchen should be totally or semi-isolated from the rest of the house because we will have solid flooring throughout and sound will really carry around the main floor. Plus, an open floor plan is just not in the style of this house. Thanks everyone, so far. I think the question of the full bath has been answered.

OK...let me get this straight. You have a plywood subfloor. That means there should be no NEED for a vapour barrier. The vapour barrier will be BELOW the plywood (somewhere in the basement or somewhere in the crawl space). If there isn't one, then there can be issues. If you are over a crawl space, you can do yourself a favour by looking to see what type of barrier is there. Vapour barriers are not allowed to be used over top of plywood sheathing. It creates more problems than it solves. The best you can hope for is a moisture retardant membrane (allows some moisture to move through slowly). With hickory - which is a hardwood that likes to move...A LOT - in a 4" wide plank, you would do VERY WELL with a glue-assist method. Technically a "wide plank" is anything 5" or WIDER. But hickory is such a dynamic wood that it can be ranked as "wide plank" in the 4" width. This is the fun of working with hickory. It takes MORE EFFORT to keep it happy. And happy starts when it is acclimating. And keeping it happy once it is installed means keeping the humidity in a tight range. You do not want SWINGS. You want to stick to a 10% range (ie. 35% - 45%; or 45% - 55%) throughout the lifetime of this floor. Hickory is beautiful. It is a diva. And like all Divas it takes a bit more care and attention to details.
