I wouldn't worry about that fill valve, Jerry. My old Maytag leaks into the tub, but it is as simple as shutting water off to it when its not in use. Which everyone should do anyways. I was a BPI Energy Auditor before retiring and I have seen so much damage done to a home, just from a burst washer hose that nobody expected because someone was too lazy to shut the water off to it when they were done.
