The Issue In The Water Supply Valve
If you have no idea where your toilet’s water supply valve is, you will see it in the backside bottom, which will be attached to the plumbing system. There will be a knob in a water supply valve that you can rotate to turn off the water.
Suppose there is any issue in this valve. You might hear a whistling sound when flushing the toilet. Many people usually keep the knob closed after using the toilet if there is a leak in the water supply valve. Sometimes accidentally, when cleaning the toilet, the valve might get partially closed, or kids might try rotating it and leave it closed.
In such a situation, when the valve is partially closed, you will encounter such noise when flushing, so to fix the issue, you can check if the valve is closed. If yes, turn the knob clockwise to open it completely, and then try flushing the toilet. Most probably, this will sort the issue. If the issue is not with the water supply valve, search for the other possible causes.
Issues In The Fill Valve
Now you might know where is the water supply valve located. Apart from this, another important component is the fill valve. It is very simple if you have no idea where this valve is. You might not see the fill valve from the outside as this will be located inside the toilet tank, so when you lift the lid, you will be able to notice this valve.
Water stored in the toilet tank will drain once you flush the toilet, and the fill valve will supply water to refill the tank. If you suspect the issue is in the valve, you must first ensure it, so remove the lid of your toilet tank and try flushing it. If you notice the sound is from the fill valve, there will be dirt blocking the valve. Hence to fix the issue, you will need to clean the valve.
Make sure you close the water supply valve by rotating the knob. Then, if water is stored in the tank, you will need to flush the toilet to drain all the water. Then you can carefully remove the fill valve and clean all the dirt, debris, and mineral deposits present in the valve blocking the water supply, which is why you hear the whistling sound.
To sort out the issue, you must thoroughly clean and fix the valve properly. Now you can open the water supply valve. After the toilet tank is filled, try flushing the toilet again. Hopefully, you might not hear the sound as you cleared all the blocks.
