This seems to happen to me all the time. I just bought an older home and have some work to do before I move in. i thought it would be a good idea to turn off the main water supply since I won't be back at the house for a week or so. When i turn the valve back on it now has a slow leak from the stem. Seems like any of the shut off valves that haven't been operated for years will start leaking if I turn them.
