Bathroom tub/shower leaking into basement
Hi. Every so often when I go down stairs I notice water is dripping rather steadily onto the basement floor - enough to stream down to a drain some distance away. This can continue for hours. One day, for instance, i noticed it occurring early before work and came home at lunch and the leak was continuing.
I noticed that when I see this happening - if I go upstairs and turn both the hot and cold water on and let them run for a minute and then turn them both off again... the leak stops.
This leak may not happen for a couple weaks of showers/baths and then may happen a couple days in a row. I have not noticed any particlar pattern for the frequency of the leak but have noticed it stops each time after letting the water run in my bath tub and then turning the water off. Anyone have any idea what it might be and how I may fix it? Help!
