...if you have one of those drain thingies in your driveway? And it's been kind of plugged up ever since you moved into the house? And it drains slower and slower as time goes on? And a heavy rainfall warning has been issued, along with a forecast of steady rain for the next several days?
Call a plumber. Just a suggestion...not that we have any personal experience or anything.
(The plumber should be here tomorrow...and we expect our bank account to be drained even more than the driveway. Bleh!)
