This sound is so well known to people of all ages, that whenever we hear something else after flushing, it causes distress.
And frankly, it should.
A noisy toilet flush can be annoying, but also an indicator of a serious problem which shouldn’t be ignored. Fortunately, toilets can be repaired with basic plumbing tools in a short time. It all comes down to the type of sound.
So if you,
Then, check out the most common toilet noises and how to possibly fix them.
Foghorn sounds are typical for older toilets with a metal ballcock-style fill valve. There is probably a loose washer in the ballcock assembly. You can replace the washer or change the whole ballcock, which would be better in the long run.
Here is an easy way to check if you need to replace the washer. Open the toilet tank and flush. As the valve starts making the foghorn sound, grab the float ball and lift it to the top of the tank. If the noise stops when you do that, then there’s a washer in the ballcock mechanism which is faulty.
If your toilet makes an air noise such as hissing sound after flushing, then the fill valve is malfunctioning. Your toilet tank has two valves inside. One, which allows the water to go to the bowl, and another which refills the tank after flushing. When the refill mechanism is blocked, it creates water pressure in the refill tube, which is higher than normal. That, in turn, creates vibrations which sound like hissing.
A water hammer in the pipes results in banging noises after flushing the toilet. Water hammers happen when the water inside your pipes comes at a dead stop, and then it hits the pipes at high speed. If this problem is ignored for a long period of time, the pipes might get damaged.
All of your pipes likely have air-filled chambers on every corner which act as shock absorbers. However, these chambers sometimes get filled with water, and that stops them from absorbing shocks. To fix this problem, you need to drain all your pipes of water.
If the noise still persists, you will need to install a slow shut off valve.
If you hear your toilet give out gurgling sounds, there’s probably a blocked line somewhere. The blockage is either in the drain system or your home’s vent stack (the pipe leading all sewer gases to escape through the roof). As a result of the clog, air can’t flow through the lines, so it pushes back, creating the so-called negative pressure. Another symptom of this problem is when the water in the toilet bubbles.
Plunging should fix the problem if it is indeed in your drain pipe:
Most of the time the noise comes after flushing, however, it’s not uncommon to hear it when the toilet is not used. There are three main reasons for this:
