venting

How important is it for each fixture to have its own vent pipe to the main vent? My log home has a bathroom wherein the lav, toilet, and shower drains attach to the main stack, which is vented. However, there aren't vents from each individual fixture. I think this situation is a result of the complications of log construction, but do I need to address this?

I'm not a plumber, but if each fixture is not vented, its drain will not function properly. Check with the contractor or plumber who did your home to find out what is what. The main question: "Is it all working properly now?" Good Luck!

Each fixture has to have it's own vent just after their respective traps, but these vents can be tied together in the attic and run through the roof with only one 2" vent pipe. Fewer holes in the roof mean fewer possibilities of a leak.

I depends - If the distance from the drain to the stack isn't that great (and your drains seem to work OK) then you don't really have a problem. The venting is just to keep the drains flowing - without them you would have a vacuum & the drains would be slow.

Being a plumber and clening drains for many years, I disagree on the vacuum therory, the vent is there to keeps sewer gases out, I have seen drains not vented or improperly vented drain real good, what happens is it drains and in the end of the drain it will pull air through the trap.
Now if you don't smell the gases or hear gurgling sounds then they all could be vented, tied to one main vent stack.
