How to Fix It:

  1. Remove the toilet tank lid and flush the toilet.
  2. Watch the flapper—does it seal completely after the flush?
  3. If it doesn’t close properly, replace it with a new one (available at any hardware store).
  4. Install the new flapper by hooking it onto the flush valve and reattaching the chain.

2. Adjust the Float to Stop Water Overflow

🔹 If the float is set too high, the toilet continuously refills and overflows into the tube.

How to Fix It:

  1. Locate the float ball or float cup in the tank.
  2. If using a float ball, gently bend the metal arm downward to lower the water level.
  3. If using a float cup, adjust the screw or clip on the fill valve to lower it.
  4. Flush the toilet and check if the water stops at the correct level (usually about 1 inch below the overflow tube).

3. Clean or Replace the Fill Valve

🔹 Over time, debris or mineral buildup can affect the fill valve, preventing it from shutting off properly.

How to Fix It:

  1. Turn off the water supply to the toilet (the shut-off valve is usually behind the toilet).
  2. Remove the fill valve cap and check for debris.
  3. Clean it by rinsing it under running water or using a small brush.
  4. If the valve is still not working, replace it with a new one.

4. Check for Silent Leaks with the Dye Test

🔹 Sometimes, water leaks silently without obvious signs. A quick dye test can reveal hidden leaks.

How to Do It:

  1. Add a few drops of food coloring into the toilet tank.
  2. Wait for 15-20 minutes without flushing.
  3. If colored water appears in the toilet bowl, there’s a leak—most likely from the flapper.

Solution: Replace the flapper or adjust the chain length to ensure a tight seal.
