Plumbing Fix #4: How to Stop a Toilet from Running
Stopping a toilet from running is usually a fairly easy fix, so don’t call your local plumbers before trying to repair it yourself. A running toilet is usually caused by either the water level in the tank being set too high or a worn out rubber flapper between the tank and bowl.
To adjust the water level in the toilet tank:
- Remove the lid from the toilet tank.
- Turn the adjustment screw or slide the rod to lower the float in the tank.
- Flush the toilet, and allow it to refill.
- Check tank water level to make sure it’s below the top of the overflow tube.
- If the water level is still too high, continue to adjust the float height as needed.
To replace a toilet tank flapper:
- Turn off the shutoff valve below the toilet by turning it clockwise.
- Flush the toilet to remove the water in the tank.
- Remove the rubber flapper at the bottom of the tank.
- Remove the flapper chain from the tank handle rod.
- Wipe off the rim of the drain at the bottom of the tank.
- Install a new rubber flapper.
- Attach the new flapper chain to the tank handle rod.
- Turn the water to the toilet back on.
- Allow the tank to fill up and check to make sure the toilet stops running.
- Adjust the flapper valve chain on the handle as needed so the toilet flushes easily.
