Hi guys,
I'm building out our 1929 bungalow attic and would like to add a bathroom above the existing 1st floor bath. I'm aware that I need to make sure that the first floor bath is vented properly. I have two vents terminating out the roof. One is the 4" CI soil stack, another is 2". I found this strange looking fixture on the soil stack and believe it is serving to vent the 1st floor toilet.
Have you guys seen this type of fixture before and could you tell me a bit about it?
