I bought a log cabin kit home that was erected by the previous owner and abandoned. It is in North Carolina which uses IPC, discharging to a septic tank 15 feet behind the home. It is one bedroom and one bath downstairs with a full width 14 foot deep loft upstairs. The attached drawing shows only the front half of the home. The 2nd story loft is supported by 4x10 beams on 30 inch center, with 2x6 tongue and groove flooring. The tub shown on the attached drawing is to be a center drain shower.
By nature of being log walls and open beam ceilings, venting of fixtures is a problem. I concidered running the stack up though the plumbing wall by the tub but this puts it out in the middle of the loft, and a long way from the kitchen sink. Can I possibly run my drain system as shown, with only one main vent stack in the corner of the kitchen. Could this be one big circuit vent if all fixture drains are limited in length to those shown in Table 909.1? If not, what if I ran a loop vent at the kitchen sink and used an AAV at the laundry and at the bathroom vanity. Also, is it a really bad idea to have the building drain turning 135 degrees?
In the future we may want to add a 1/2 bath upstairs, which could be a 3 inch stack vertically down through the plumbing wall installed by the tub shown and tied in to the building drain where ever appropriate and joining the through the roof vent in the attic. Did I totally miss the boat on this one? Thanks for your feedback.
