We have an unvented kitchen sink (old plumbing, never vented). The sink is below a window, and the nearest access for a vertical vent up is about 3-4 ft away horizontally.
I don't think we can get 6" above fixture rim due to the window height. Is the island venting approach the best? I have seen references to the "dirty arm" approach but am not sure exactly what the details would be. I also understand AAV, but would like to avoid it if possible.
We are in Illinois, and I will discuss the details of the approach with our plumbing inspector, but wanted to understand what the options are first.
Thanks very much!
