A toilet that never stops running isn’t just annoying—it’s wasting hundreds of gallons of water every day. The most common culprit is a worn-out flapper valve. This rubber seal at the bottom of your toilet tank controls the water flow to the bowl. When it no longer seals tightly, water leaks slowly into the bowl, causing the tank to refill repeatedly.
Check the flapper by removing the tank lid and pressing it down. If the sound stops, that’s your issue. Replacement flappers are inexpensive and easy to install. Another possible cause is an improperly set float or a faulty fill valve. If the water level is too high, it spills into the overflow tube, keeping the refill cycle active.
Adjust the float until the water level sits about one inch below the overflow tube. If that doesn’t fix it, your fill valve may need replacement. Sediment buildup in Elmhurst’s municipal water can also affect toilet parts over time.
