I am building a 24' x 44' cabin. Plans have been approved, foundation walls have been poured and am roughing the plumbing in the basement before the slab is pour. The basement has 8 foot tall walls.
There is a kitchen sink on first floor.
Full bathroom on first floor (sink, shower, toilet).
Full bathroom on second floor (sink, tub, toilet).
Floor drain in basement.
Each 3 set of fixtures is just above the stack individual stack in the basement.
All 3 main stacks will be vented out the roof.
Basement slab design (see attachment) is 3 stacks draining to basement, and a floor drain all emptying into a 4" pipe that leads to the septic tank. Cleanout just outside the foundation wall before septic tank.
1)If all three stacks coming from the first floor are vented to the roof, do I still need an additional vent in the slab?
2) Do I need a cleanout inside the basement if I have a cleanout just outside?
3) To pressure test the system, do I just:
a) plug the 3 stacks, floor drain, and connection to the septic line
b)pressure the pipe with air
c)assure no leaks for 15 minutes
Thanks for your help
