I have a 5-yr-old house with an odd plumbing problem. What happens is
that if I or my
wife runs the water in the sink in the upstairs bathroom, air gurgles
up through the toilet. And it seems to be just air, there's no odor
to it. Nothing happens when we run the
shower.

At the same time, we sometimes have weird problems with the upstairs
toilets (there's
one other bathroom upstairs). For no apparent reason they'll both get
plugged up at
once.

I tried using Drano on both upstairs bathrooms but it didn't seem to
help. Anything else I should be doing?

As noted, you likely have a blocked vent or drain (likely outside your
home).
