Dripping Sound Inside Toilet Tank, What to Do?

Tip! Tap! Tip!

The incessant noise continued after every small pause. Just when you thought it was gone, it crept into my ears every single time. Only someone who suffered from the dripping sound inside the toilet tank would know how annoying it can be. After almost a year of losing my sleep over this constant noise, I had enough!

That’s when I realized that I either needed to do something about this or go on vacation for some peaceful sleep. Since the latter was just a temporary solution, I started researching how to diminish the dripping sound. And today, I decided to discuss them all in detail for a one-stop solution to all your problems.

Why Is There Dripping Sound in My Toilet Tank?

A dripping sound in the middle of the night can often be too irritating to bear. Some might think it’s not that big of a deal, but it can surely lead to some sleepless nights, or even worse, cause flooding. Whether you like it or not, it’s pretty apparent that there is a problem with your plumbing system.

There can be a handful of reasons for the dripping sound you hear 24/7. Here are some of the possible causes listed below.

Toilet Tank Issues

The dripping noise in the toilet tank doesn’t always mean that the toilet is clogged or overflowing. In fact, this can be caused by a simpler issue in the plumbing system. For example, all toilets have an overflow tube that reaches the bottom of the fill tank. When this tube ages, it is prone to cracking and leaking.

The leaking tube can often be the root cause of the dripping noise after flushing the toilet. An unstable flapper can also cause similar problems. It can leak significant amounts of water if it’s not mended on time.

You can diagnose this issue by taking off the lid and flushing the toilet. Then you need to notice whether the tubes start leaking.

Slow Drain Issue

A faulty drain can also cause a dripping sound in the wall after flushing the toilet. This can often be due to a slow drain which is probably clogged up by debris. The flow of water is pretty slow inside the pipes when this happens. You can easily take care of this issue without having to replace or remove the drain entirely.

Leaky Faucet

Leaky faucets are often the main cause of the distracting noise coming from your bathroom. It might be pretty difficult to locate the faulty faucet due to the slow rate of dripping. There can be several reasons for this malfunction. For one, there can be an accumulation of leakage in the spout due to a broken O ring.

If the faucet is too hold then, it’s possible that it has gone through some internal corrosion. This can damage the seals, which usually stop the faucet from dripping. The seal performance can also be deterred by the level of minerals in the water.

Cracks in the Pipe

Sometimes the dripping sounds tend to emanate from the walls rather than the bathroom. This is a sign that there might be something wrong with the pipes. Thermal expansion can be one of the causes of this dilemma. Unusual changes in water pressure are also a contributing factor.

Sometimes air trapped inside the pipes can also damage them. A cracked pipe should be mended as soon as possible as leakage inside walls can damage them internally.
