I seem to have the classic problem of a clogged vent; flush toilet and shower drain "gasps".
Is there a good alternative to going up on the roof and clearing it from there? What's the recommended tool, if the problem isn't just a bird's nest -- standard drain auger from the top?
(I've climbed lots of roofs in my time, but I'm getting just old enough that I may want someone else to deal with that.)
Folks have asked about availability of clean-out T's. I don't think there's currently one that will let me hit this vent. I do have attic access, so could presumably splice something into the PVC there to reduce climbing in the future; doing it without disturbing whatever seals the roof penetration might be tricky, though.
