In response to Re: How do you make a loop vent.
There are at least three ways to make a loop vent. Usually only one of them is approved in any given area. Your building inspection department normally will have a sheet showing how they want it done.

: Where can I find information on how to construct a loop vent? Do the DIY books cover this?
: How do they work so that sewer gases don't come back through?
