If you hear a loud noise after you flush your toilet, you need to know that there are several possible reasons behind this. As a rule of thumb, a loud noise that takes more than a minute after you flush the toilet indicates a problem with water pressure or a restricted water flow. In any case, it is important to address the problem with the help of a specialist, as sometimes the noise is a symptom of a serious problem that may cause major water damage.
Replacing A Dirty Toilet Valve
One of the most common causes of a noisy toilet is a dirty valve. If that is the case, your toilet is likely to be making a noise that resembles a loud foghorn. The good news is that this is actually easy to fix. First you need to turn the water supply off, and remove any dirt and debris you can locate into the valve. Check for any kind of leaks before switching the water back on, and the noise should be gone. If this doesn’t solve your problem, you might need to fit a new ballcock and valve.
Dealing With The Water Hammer
If your toilet makes a noise similar to humming, you will need to replace the ball valve. To do so, split the ball valve in two and you will see a washer inside. If it looks very worn, it is time to replace it. However, in some instances, you may need to replace the entire valve. A dirty valve causes pressure in pipes, which in turn can cause a loud banging noise. This should disappear as soon as you replace it.
A Float Switch
If you notice that water overflows from the reservoir or “cistern”, you may need to change the float switch of your toilet. In many cases, all you need to do is unscrew and reassemble the float to regulate the water flow, but sometimes you may need to put one in. You can do so by yourself, or with the help of a professional plumber.
How To Deal With Bad Vibrations
Sometimes, simply clearing out the valve does not fix the noise so you may need to dig deeper than that. It is possible that a loose connection may occur somewhere in the cistern. Check this by turning the heater off and unscrewing the entire mechanism, including the valve. Next, take the washer out and put it back the other way round. Put everything back on, and turn the water on to see if the problem is fixed.
