It started with well water coming in black in one toilet upper level. After a couple of days the other upstairs toilet started going gray. The shower and sinks are now starting to go gray. We poured some bleach directly into the well to flush it. When we flushed it in the past the water would do this. We just never had it do this on it's own.We have had steady rain for a couple weeks. Well is 180 ft. Door Co. WI
