Step 1: Turn off the Water Supply
The first thing you need to do is turn off the water supply to the toilet. Locate the isolation valve which is typically located behind the toilet or under the sink in your bathroom. Once you have found the valve, turn it off clockwise until the water supply is completely shut off.
Step 2: Flush the Toilet
Flush the toilet to drain out any remaining water in the cistern. Once the toilet is completely flush, use a sponge or a towel to remove any remaining water.
Step 3: Remove the Cistern Lid
The next step is to remove the cistern lid. This can typically be done by unscrewing any bolts or clips that are holding it in place. If you are having trouble removing the lid, refer to the manufacturer’s guide for specific instructions.
Step 4: Identify the Problem
Once you have removed the cistern lid, inspect the cistern for any visible signs of damage. Look for cracks, chips or leaks in the water inlet valve, flush valve, or overflow tube. If you identify any damages, these parts will need to be replaced.
Step 5: Replace the Damaged Parts
If you have identified any damaged parts, you will need to replace them. Make sure you purchase parts that are compatible with your toilet model. You can purchase replacement parts from any hardware store or online. Once you have the replacement parts, follow the manufacturer’s instructions on how to install them. This typically involves unscrewing the old parts and attaching the new parts in their place.
Step 6: Check the Float and Fill Valve
If you did not identify any visible leaks or damage, the problem might be with the float and fill valve. The float and fill valve controls the water level in the cistern. It is located near the water inlet valve. The float should move freely and the fill valve should stop the flow of water when the cistern is full. If the float is stuck or the fill valve is not working properly, they will need to be replaced.
Step 7: Reassemble the Cistern
Once you have fixed the problem or replaced any damaged parts, reassemble the cistern. Make sure all bolts or clips are securely in place. Tighten them as needed, but be careful not to overtighten, as this can crack the porcelain.
Step 8: Turn on the Water Supply
The final step is to turn on the water supply to the toilet. Slowly open the isolation valve clockwise until the water supply is fully restored. Wait a few moments for the cistern to fill up again. Then, flush the toilet to make sure there are no leaks.
In conclusion, fixing a leaking toilet cistern may seem like a daunting task, but it is actually quite simple. By following the above steps, you can easily fix a leaking toilet cistern on your own. It is essential to act quickly to prevent water wastage and potential property damage. If you encounter any difficulties during the repair process, it is recommended to seek professional help.
