Can vent pipes have elbows or do they have to go straight up through the
roof??? Thanks for any help....

They can go any which way you can think of, as long as they don't have
bends that will hold water (like a P trap) to close off the air exhaust.

Further. To avoid several holes in our roof (kitchen, bathroom, main
stack etc.) we took all our vents through the attic to one place (the
main vent stack) and joined them all together for one vent through the
roof. The kitchen for example is some 20+ feet from the main stack
vent.
Been that way since 1970, no problems. Everything vents as it should.

All plumbing whether going down (sanitary sewer) or up (venting)
can make turns and joints. The fittings must all be sanitary
fittings, not pressure fittings that make sweeping turns that
solids and sewer cables can maneuver.

A very old method of inspection was to drop a ball into the piping
to see if it would come out on the down hill end. I've not ever
seen it, it may be a myth, but the concept is accurate.

What if the ball didn't come out?

This might or might not meet code in some areas. Here in central Ohio USA I
think it does, but I think in some areas it may not. Regardless there is
probably some limit to how many fixtures (sinks, tubs, toilets) that can go
thru one vent.- Hide quoted text -

In this area it would'nt has we won't allow more than 2 45s at most to
a stack and 3 toilets least it is 6 inch Remember that no toilet
should be more than 5 feet from the stack as this is physics of water
not some code. Also if doing sinks after 10 ft they should be done in
2 inch as better flow is achieved. And after 12 feet a secondery vent
is required just makes for better flow and drainage.
