Toilet Cistern Not Filling Up: How to Fix It?
You might have pressed the flush button, but it somehow doesn’t work. Then you try to open the toilet lid to check if something is wrong, but you have no idea what to do next. Don’t worry, as this post has gathered relevant information to sort it out.
1. Make Sure the Shut-Off Valve Is Open
A toilet is equipped with a shut-off valve that looks like a small handle or button that regulates the water circulation into the toilet drain. It is frequently seen either in the back or next to the toilet tank.
One of the most typical reasons for a cistern not refilling is that the shut-off valve is not open. Consequently, water is not possible to enter the cistern and move throughout the toilet.
In this case, it is crucial to inspect whether the shut-off valve is already open by moving the handle with the clock hands. Once you have done this step, the water will begin moving into the toilet structure. However, if you observe that no water is flowing inside, you may proceed to another method.
2. Test the Water Pressure
If the power of the water circulation in your house is low, it may take a long time for the cistern to be filled with water. Therefore, it is recommended to review the pressure level in your property.
If the pressure is weak throughout the whole infrastructure, you can reach the water supply to solve the problem. However, if the water flows slowly in the toilet but not in other parts of the house, there may be cracks or blockages in the pipeline that require professional repair.
3. Reposition the Float Ball
Inside the toilet tank, you will find a float ball that plays a crucial role in managing the water flow in the cistern. This ball should be positioned accordingly to function properly. That’s why it is important to observe the placement by following these steps below.
Firstly, you should temporarily disconnect the water line to the toilet by closing the shut-off valve. Then you should eliminate the majority of the existing water inside the tank by flushing the toilet. Afterwards, you can open the tank lid to observe the condition of the float ball.
Raise it to test if the water begins to fill the cistern. If nothing changes, you may proceed with searching for the screw that connects the long arm to the lever. Rotate it clockwise to increase the waterline inside the tank.
Make sure that the screws are not overstretched while you adjust the position of the ball or the screw. Then you can open the shut-off valve again to start filling the water until it reaches half an inch under the tank’s overflow tube. Ensure that the float ball can glide easily with no constraint before closing the tank.
4. Ensure the Toilet Flapper Is in Good Condition
The flapper is a plug made of rubber that is located at the bottom of the toilet tank, which rises when flushing to release the water to pass into the toilet bowl. If the flapper is malfunctioning or fails to close the tank correctly, the cistern won’t store the water, and the toilet will not fill with water.
To observe the condition of the flapper, you should empty the cistern first by closing the shut-off valve and flushing all the water down. If it appears damaged or does not close firmly, swapping it with a new one is necessary.
If it still looks appropriate, you may inspect if there is any obstruction below the flapper and on the flush control valve. In this case, you can keep the water flowing until the blockage is removed.
5. Install a New Overflow Tube
The toilet tank is equipped with an overflow tube that keeps the cistern from being overfilled by draining the surplus water into the toilet bowl. If the pipe is damaged, it will cause a leaking toilet in Sydney, and the cistern will not fill up with water.
Therefore, it would be best to put in a new overflow tube or the whole flush valve component to replace the old ones.
When Is It Time to Contact a Plumber in Sydney?
Some toilet cistern cases might be too complicated to resolve with DIY techniques. Therefore, if you have implemented the tips listed above, yet the problem remains, then it is the perfect time to seek professional assistance from a plumbing expert.
Complicated plumbing problems demand advanced equipment and expertise. A certified plumber in Sydney possesses these two qualities to evaluate the whole toilet and plumbing structure and complete the necessary adjustments or upgrades. Moreover, it will also spare you some time and save you from the frustration of the long-overdue plumbing issue.
Conclusion
Numerous issues can be the reason for the toilet cistern not filling up as it should. It can start with a very minor trouble, like a shut-off valve, but it can also be caused by more intricate plumbing errors that must be addressed with specific skills that are possessed by a qualified plumber in Sydney.
If you have tried your best to identify the underlying cause and fix it on your own, yet the problem remains unsolved, it would be best to hire a reliable plumbing technician to tackle it professionally and to avoid more unfortunate situations in the future.
Finally, maintaining your toilet cistern after it is repaired will save you from the same issue happening again.
