The mysteries of a running toilet can drive you nuts. Whether you hear water running constantly or cycling on and off, we’ll help you decipher the clues so you can stop wasting water. Hardware stores and home centers carry the parts for almost all toilet repairs. One cause of a toilet running is a flapper that doesn’t seal. If water from the tank seeps around the flapper and into the bowl, the flapper is probably shot.
Flush the toilet and look for a fill valve leak. Lift up on the toilet float arm when the tank is filling to see if the water stops. Bend or adjust the toilet float arm so the tank stops filling when the water level is 1/2- to 1-in. below the top of the overflow pipe. If the fill valve still leaks, replace it.
