- 1). Take off the tank lid so that you can look inside the toilet tank.
- 2). Check the locknut that holds the flusher in place. If it is too tight, this can result in a sticky flusher. If the nut is too loose, this can result in a wobbly handle.
- 3). Check the water level and float. The float is the ball that extends from the water line and control assembly. The water level should be 1/2 to 3/4 inches below the top of the white, plastic overflow tube. The float should be resting naturally on the surface of the water. An incorrectly positioned float valve can result in low water levels, which can affect flush pressure or create a running toilet. Use a screwdriver to turn the adjustment screw on the arm of the float to raise the float and water level. If the float is damaged, it should be replaced.
- 4). Turn off the toilet water valve and flush to run all the water out of the tank.
- 5). Look at the refill tube while the toilet flushes. The refill tube has a spout that is supposed to spit water into the overflow tube. If the refill tube has been somehow moved so it is spitting water into the tank instead of the overflow tube, this can cause splashing sounds whenever you flush. Simply put the spout back into the overflow tube, where it belongs.
- 6). Look at the chain that connects the flush handle to the rubber flapper valve at the bottom of the toilet. The chain lifts the flapper valve up and down. At rest, the flapper valve holds tank in the water. When the flusher is pressed, the chain lifts the flapper up so that the bowl can be filled. If the chain has become unhooked, this can prevent the toilet from flushing. If the chain is tangled and is not letting the flapper go down all the way, this can cause your toilet to run.
- 7). Inspect the flapper valve. If the flapper valve is encrusted with crud, it can be cleaned with a bleach cleaner. If the flapper valve is worn or damage, it should be replaced.
