What controls water flow inside a washing machine?
We needed to paint behind a washing machine and turned the valves off and unhookd the two hoses at the washer. There was a drip drip out of the top hose end. So the valve does leak though it's shut off. But both valves are on 24/7 so the washer can be used at any time. What part inside the washer prevents water (that standing in the hoses and being under pressure since the valves are on 24/7) from leaking?Thanks.
