What I have in my basement could loosely be called a drain. It doesn't have a pipe. Best I can tell, they just cut a 3 inch hole in the floor; all you see is the rocks under the floor.
I've been draining the dehumidifier into this but I wonder if it's really that great of an idea. Before I did that, I would get a good 2 gallons every day. That seems like a lot of water to be putting down that hole. Am I making the dehumidifier work harder by keeping the water around? Is that water just re-evaporating back into the basement?
