Do you have Washing Machine Shut off Valves that drip or leak after you turn them off? Do they still leak even when you turn the Main water line off? I had that problem...Then I fixed it.

This video might be good info if you're thinking of doing the same thing BUT it should not really function as a tutorial. I run into some problems but those problems might help you on your journey toward nonleaky valves.
