Inspect the Flapper
To check if the flapper is the source of the leak, remove the tank lid and observe the flapper. The flapper is the rubber component at the bottom of the tank that controls water flow into the bowl. If it is worn, warped, or not sealing properly, it needs to be replaced.
-
Turn Off the Water Supply
Before making any repairs, ensure the water supply to the toilet is turned off. Locate the shut-off valve, usually found behind the toilet near the floor, and turn it clockwise until it stops.
-
Drain the Tank
After turning off the water supply, flush the toilet to drain the water from the tank. Hold down the handle to allow as much water as possible to exit. Use a sponge or small bucket to remove any remaining water.
-
Replace the Flapper
If the flapper is identified as the source of the leak, it’s time to replace it. Remove the old flapper and install a new one, ensuring it fits snugly over the flush valve seat.
-
Check the Fill Valve
If the tank continues to overfill, the fill valve might be the issue. Adjust the fill valve or replace it if necessary to ensure it shuts off the water at the correct level.
-
Tighten Tank Bolts
Leaky tank bolts can also be a source of leaks. Ensure the bolts connecting the tank to the bowl are tight and not causing leaks.
-
Reconnect the Water Supply
After making the necessary repairs, reconnect the water supply. Turn the shut-off valve counterclockwise to restore the water flow.
-
Test for Leaks
Once the repairs are complete, turn on the water supply and allow the tank to fill. Flush the toilet several times and check for any signs of leakage around the tank and base.
