Nothing could be more annoying than the sound of a toilet that won't stop running. Just as bad is the spike in your water bill that this problem often leads to. Luckily, in many cases it doesn't take the skills of a professional plumber to solve this problem. If you would like to learn more about repairing a malfunctioning toilet, read on. This article will introduce you to two possible causes of a toilet that won't stop running--and teach you how to correct them both.
The fill tube has come loose.
The fill tube has the important job of refilling the toilet bowl each time you flush. It does this by diverting water from the fill valve into the overflow tube, which in turn leads to the bowl. The fill tube is commonly attached to the wall of the overflow tube with a small metal clip. Over time, the force of the water rushing through the fill tube can jar this clip loose. This keeps the toilet from receiving the important signal to stop filling with water.
Remove the lid of your toilet and check to see whether the fill tube is attached correctly. If so, flush the toilet. As the tank begins refilling, watch the water coming out of the fill tube to make sure that it is aimed properly into the overflow tube. Make any adjustments as needed.
The fill height needs to be adjusted.
As its name would imply, the fill height dictates the amount of water allowed to flow into the tank before the filling mechanism shuts off. If the fill height is too high, water will spill from the tank into the overflow tube, thus causing the fill mechanism to turn on once again. The frustrating result of this cycle is a perpetually running toilet. How you adjust the fill height is different depending on which type of toilet float you have. There are two principal varieties: ballcock floats and cylinder floats.
Ballcock floats can be adjusted by making changes to a special screw. This screw is located at the opposite end of the metal rod from the ballcock itself. Turning it in a counterclockwise direction will lower the fill height. Work in small, quarter turn increments until the fill height is just low enough to keep from spilling over into the overflow tube.
The adjustment process for a cylinder float is slightly different. You should find that there is a metal rod attached to the top of the float with a spring clip. Pinching this clip will allow you to change the height of the rod--and thus the tank's fill height. Slide the rod downward to lower the fill height to the appropriate level.
