Went away on Tues and came back today. Before I left I shut off the main water supply at the hot water heater. I turned on fawcett in the kitchen to see if it was off. Trickled for a second so I assumed it was off. Came back tonight and washing machine was filled to the top and I think it overflowed because The floor is wet. How could it fill up without anyone turning it on, epcially when main supply was off?? Thanks.
