Fix Running Toilet

Tools

• Adjustable wrench
• Screwdriver
• Towel or sponge

Materials

• Replacement flapper (if needed)
• Replacement fill valve (if needed)

Safety

• Turn off the water supply to the toilet before starting repairs.
• Wear gloves to protect your hands from dirty water and cleaning chemicals.
• Dry up any spilled water promptly to prevent slips.
• Do not overtighten plastic parts to avoid cracking.
• If you notice leaks after repair, stop and consult a professional.

Steps

1. Step 1: Turn off the water supply

   • Locate the shut-off valve behind the toilet and turn it clockwise to stop water flow.

   Check: Ensure water is completely off by flushing the toilet and confirming the tank does not refill.

2. Step 2: Remove the tank lid

   • Carefully lift the toilet tank lid and set it aside on a flat surface.

   Check: Check that the lid is placed securely to prevent breakage.

3. Step 3: Inspect the flapper

   • Look at the rubber flapper at the bottom of the tank. If it is warped, cracked, or doesn’t seal properly, it may need replacement.

   Check: Confirm the flapper is sealing tightly against the flush valve.

4. Step 4: Replace the flapper if necessary

   • Disconnect the chain and unhook the old flapper from the pegs.
   • Attach the new flapper and reconnect the chain, ensuring proper length (slightly slack when at rest).

   Check: Test the flapper movement by pressing the flush lever and ensuring it drops back into place.

5. Step 5: Check the float and fill valve

   • Examine the float to ensure it moves freely and is not set too high.
   • Adjust the float arm or screw to set the water level about 1 inch below the top of the overflow tube.
   • If the fill valve is faulty or leaking, replace it according to manufacturer instructions.

   Check: Verify the float does not stick and the fill valve shuts off water at the correct level.

6. Step 6: Turn the water supply back on and test

   • Slowly turn the shut-off valve counterclockwise to restore water.
   • Allow the tank to fill and flush the toilet several times to check for proper operation.

   Check: Ensure the toilet stops running after each flush and there are no leaks around the base or inside the tank.
