Hi everyone,
I live in British Columbia, Canada
i am planning to make a bathroom in my second floor bedroom.
The main stack is pretty far away from my bedroom. So, i do not want to break the floor, wall, and studs to connect my solid line to the main stack.
1. so, i am wondering is it possible to connect my toilet and sink to the main stack from the outside?
2. for the venting problem, i am planning to attach an Air Admittance Valve(AAV) on the top of the outside solid line. The AAV i am getting is an abs 2" X 1-1/2" thread-on adapter. 20 DFU'http://www.homedepot.ca/product/abs-air-admittance-valve-with-threaded-adaptor/968663
The reference from this site states that 1 bathroom and 1 sink has around 9 DFU. In my case, a 20DFU AAV would be good enough right?http://www.vbgov.com/government/departments/public-utilities/rates-fees-charges/Pages/drainage-fixture-units.aspx
3. Do i need another dry venting? If so, can i just add another AAV under the sink ?
Any help would be nice
Thank you
