Why is there a whining noise when you flush the toilet?
If you flush your toilet one day, and you start to hear a whining noise, you are going to want to know how to deal with it. It could be that the cause is something straightforward, like a valve not being as open as it should be. It could also be that there is a problem within the ballcock assembly.
We are going to take a look at what could be the cause of a whining noise when you flush your toilet. If you feel confident enough to investigate the problem for yourself you should find this information useful. If you would rather leave the task to a professional you can just contact a plumber in Lane Cove. They will make sure the problem is resolved as soon as possible.
Checking the shut off valve in your toilet
As we mentioned in the introduction, it could be that the whining noise you hear is happening because there is not enough water getting to the refill valve in the toilet. In order to see if this is the case you need to check the shut off valve for the toilet. If the valve is not fully open this is probably restricting the flow of water. All you need to do is fix the shut off valve. If the problem is not with the valves in the toilet, you should go on to check the ballcock assembly.
Checking the ballcock assembly for issues
It could be that parts of the ballcock assembly are broken, or need to be cleaned; you need to check to see if this is the case. The first thing you should do is take the lid off the toilet and check to see if there is any damage to the float ball. You should also complete a check of all the washers, and make sure that they are clean. If there are any damaged washers they will need to be replaced.
Once you have done all of this you should check to see if you can still hear the whining noise when you flush the toilet. If you can, then it’s a good idea to dismantle the whole assembly and make sure that each and every part is clean. If the noise persists after you have done this it could be that you need to replace the assembly. You may want to consult with a professional plumber to confirm that this is the case.
As you can see, there can be different causes of a whining noise that occurs when you flush the toilet. The solution may be as simple as adjusting the toilet shut off valve. However, you may have to take further action in investigating the condition of the ball cock assembly. Remember, that if you do not feel confident at any point, it’s best to call a professional plumber for help. They can resolve the problem for you and give you peace of mind.
