A running toilet can be due to a worn-out flapper, improperly set float, or a leaky fill valve. To fix this issue, start by checking the flapper to see if it’s sealing correctly. If not, replace it. Next, adjust the float so the water level stops about an inch below the top of the overflow tube. If the problem persists, it could be the fill valve, which may need replacing. These steps can save water and reduce your utility bills.
