My furnace, A/C, and humidifier all drain into a hole in the floor.
A few days ago I had a minor flood. Turning off the humidifier and cleaning up, I determined it was from the humidifier. I turned the humidifer back on to see how it was leaking, and found it was at the drain.
It has been fine for 15 years; how do I clear it?
The ground is very wet now, but I am sure it has been this bad sometime in the last 15 years. The house has two sets of drain tiles that gravity feed to the lake 15 feet below the level of the walk out basement.drain.jpg
