Thanks for the input. Have you noticed any discoloration of your
driveway? I've read that the water run-off from condensation of a gas
furnace is acidic, with a pH roughly the same as orange juice.


We sold that house about 10 years ago. During the 8 or so years that I saw
it drip there I did not see any. It was a blacktop drive. YMMV on concrete
because of the chemistry involved.
