Hi. I can hear my condensate pump coming on and off all the time. When I first noticed, I took a look at the deep sink where it empties, and it was (and is) about 1/4 full. The deep sink does drain slowly, but this pump seems to be out of control. Now it's been going on for 3 days. On for about 4 seconds, off for a little bit more than that, and on again.
There is no water on the basement floor, the deep sink didn't overflow, and the furnace seems to be operating normally when it's on.
Any ideas what's going on here? Is it time to call a plumber?
Many thanks for any input.
