We finally found what we have been looking for! The cause of that wet basement floor. It turns out when the wash machine is draining all the water comes up out of the floors drain and gets the whole floor soaked.
The only problem is, I don't know what to do about it. Do we get the drain snaked? and get it declogged. probably, anyways until we get the plumber back we will have a 1/2load of towells sitting 1/2 way washed in the washer. Fun, but what else can you do with half washed towells if you don't want your whole floor wet again?
