Our commode isn't leaking, yet it refills many times a day
If your commode is refilling over and over, you may have a Ghost Flushing problem. Even though there's no water on the bathroom floor, you likely still have a slow leak somewhere in the tank. To locate and identify the source of the leak fill the tank and shut off the water to the commode. Remove the tank lid and draw a pencil line along the top edge of the water line. Leave the water turned off and go back several times and redraw the pencil line at the water line. When the water stops draining see where the water level is. If the water has stopped just below the overflow tube, you likely have a siphoning problem. If the water drains to the bottom of the tank you likely have a flapper problem.<br />To correct the siphoning problem reset the the depth of the fill tube in the overflow tube. Fill the tank up, shut the water off, and recheck after some time. Repeat these steps until the water stops draining.<br />To correct the flapper problem gently lift the flapper and clean the bottom of the flapper and the flapper seat. Refill the tank, shut the water off, and recheck later. If water still leaks replace the flapper.
