Very good points. I've tried to clear and grade the area outside the laundry walls, but the water always seems to come in when I'm not there to observe the entrance path. One good possibilty is it's coming over the backdoor 1-1/2" concrete threshold which is cracked in one placed almost to the floor surface. This I'm trying to repair ASAP, then see what happens. Haven't yet because the weather here lately has not permitted.
