My Toilet Makes Noise When Not in Use – Why?
Sometimes our customers notice that, after they flush the toilet, it makes a strange whistling or whooshing sound. Other times they notice their toilet keeps running on its own even after the tank is done filling.
Not only are situations like these frustrating (especially during the middle of the night when your family is trying to sleep) but they often waste water and can really make your water bill skyrocket.
A noisy toilet can happen for several reasons. The most common are:
- Leaking toilet valves
- Malfunctioning fill valves
- Calcium deposits have built up on the inside of the pipes.
Usually replacing a part or cleaning the pipes will help to resolve the problem. You can see a diagram of a toilet showing all the parts here.
Other Causes of Toilet Noises
If your toilet is making a vibrating sound around the wall whenever the toilet is flushed the problem usually has to do with the fill valve. More specifically, the diaphragm gasket inside the fill valve can wear down, lose elasticity, and harden. You can test whether the issue is a malfunctioning fill valve by removing the toilet tank lid and lifting the float arm gently. It is connected to the fill valve and if it stops the noise from occurring then it will have to be replaced.
There are other noises that can occur when the fill valve is malfunctioning as well. For example, if you are noticing a whistling sound it is most likely due to a slowly leaking valve. Adjusting the fill valve until the whistling noise stops may do the trick but if it doesn’t work the valve will probably have to be repaired or replaced.
Perhaps your toilet is noisy because it is running constantly. This also tends to be an issue with the fill valve not shutting off when it should. Once again, an adjustment to reset the float arm to a lower level inside the toilet can be the solution. First, remove the toilet tank lid and locate the float. There are a couple of types including a cylinder float which is attached to the fill valve body, and a floating ball type which is attached to the end of the rod.
If you have a cylinder float, on the side you should notice an adjustable clip which can be squeezed to lower the float down until it stops the water from running. If you have a float ball, on top of the fill valve turn the screw counter clockwise until the water stops running fully. For both, once you have made the adjustment try flushing the toilet once again. If you have a fill valve that is worn out or damaged then there isn’t an adjustment that will resolve the problem successfully and it is likely that you will need to have this part replaced.
Should you be noticing a whooshing type of sound when the toilet is filling up that stops once the toilet tank is full then there is likely a calcium build up. Usually in the urban part of Ottawa this isn’t a problem, but if you live just outside of town and are on a well, you may have hard water. The pipes will need to be cleaned using a calcium and mineral deposit cleaning agent. You can learn more about solving hard water issues here.
