Hi. My toilet water (in the tank at the back of the toilet) is running
non-stop. I tried shutting off the valve underneath the toilet, but it wouldn't
budge in either direction. I removed the lid off the tank, and rather than the
usual ball-type float, there is a device called a "Fluidmaster." Do you have
any suggestions just so I can stop the water from running continuously all
night? Thanks for your help!
