Using Air Admittance Valves (AAV)
 
1 Attachment(s)

I am looking at using a AAV for a new project. There is no way I can vent the lavatory without using one. I also want to do the same with a toilet.

Have you used an AAV and what are the limitations?

The Rectorseal brand seems to work for 1 1/2" applications but our code now calls for 2" lines for sinks. How did you resolve this?

The toilet drain is obviosuly much larger. Can an AAV be used in that application?

Thanks to my friends and pros who typically have great advaice!

Since we are on a main line, not a septic, I think the article you found is not applicable. Found a new manufacturer and they provided this pic. Notice they have applications for bath, sink and toilet. I will be calling them today to get more details.
