Why Is My Toilet Leaking? – Top Causes

There are various reasons why your toilet compartment would leak; some can be controlled while others are just out of your control.

Why is my toilet leaking

Some common causes of toilet leaks are broken water pipes, loosened toilet bolts, damaged valves, faulty flapper, the list goes on. We will look at each of this scenario in the following subheadings:

Toilet Leaking From The Bottom

Inside the toilet tank, a flush valve is located at the bottom of the tank. This valve prevents water from entering the toilet bowl when flushing is not carried it.

When you flush, this valve shifts allowing water to enter the toilet bowl. After this is done, it is sealed back by a gasket. When this gasket deteriorates due to wear and tear, water leaks at the toilet tank’s bottom. If this is not quickly rectified, it could affect the toilet fill tube.

Also, some leakages at the bottom of the toilet can be caused by cracks and wears. Furthermore, the bolt that secures the toilet to the ground may be faulty, resulting in a reduction in the toilet bowl water level. This scenario actually can cause the toilet to clog and produce a foul smell.

Leakages at the bottom of the toilet can be easily located. Locating these leakages may be tricky if it occurs at the bottom of the toilet tank.

However, if the leakage occurs due to a loosened bolt, you can quickly tighten up the bolt or replace it if needed. If the leakage is caused by a crack at the bottom of the toilet bowl, you can easily cover the damage up or call a plumber to fix it up.

For gasket deterioration, a plumber will have to inspect the toilet tank and make every possible fix to damaged components. The gasket also has to be replaced.

Toilet Leaking At The Base

Realizing that water leaks at the base of your toilet may be terrifying. Sometimes you don’t know where the leaks are coming from. Depending on the damages, it can result in your bathroom overflowing with water. Also, there is a probability that the leakage will disturb you from resting after a day’s job or activity.

Fixing the water leakage at the base of the toilet is more complicated than most other toilet issues.

It could involve the removal of the whole toilet to fix or replace the wax ring. The wax ring seals the base of the toilet against the drainpipe under the toilet.

Reasons For Toilet Leaking At The Base

There are various reasons why water leaks at the base of your toilet, some of which are:

Faulty Wax Ring

One usual cause of the toilet leaking at its base is a faulty wax ring. A wax ring seals the toilet to the drain pipe; this prevents the dripping of water directly on the floor.

When the ring is faulty, the toilet ground is flooded with toilet water producing a bad smell. It is advisable to stop the usage of your toilet until the problem is fully fixed.

To fix this issue:

  • Suspend the usage of the toilet until it is repaired
  • Replace the wax ring
  • Stop the flow of water into the tank then flush the toilet manually and clean the floor with a mop
  • Remove entire toilet by unscrewing the toilet bolt
  • Replace the wax ring and screw the toilet to the floor
  • Resume your toilet usage

Condensed Water Could Be Dripping Below The Toilet Base

Water below the toilet tank and toilet bowl is usually cold. Condensation and cooling of this cold water could cause droplets at the toilet tank base and bowl. This situation is normal, so you don’t have to go through the stress of fixing anything.

Faulty Bolt

The bolt helps to secure the toilet against the floor, and it consists of two screws. When this bolt is faulty, the toilet becomes loosely gripped to the floor, and this could result in water leaking massively at the base of the toilet bowl.

When this bolt becomes loose it prevents the wax ring from sealing the toilet to the drainage pipe. If care is not taken, the wax ring could get faulty.

To fix this, replace the wax ring. You can call a professional plumber to do this.

A Toilet Leaking From The Tank

Leakage of water from the toilet tank does not usually pose a significant problem, unlike that from the toilet base. Usually, the leaks occur at the bottom part of the toilet tank and are usually indicated when the tank is refilled.

Causes of a leaking toilet

If you notice that the water in your toilet tank keeps depleting after being refilled, that is a sign that there is a leakage somewhere.

A faulty gasket, spud washer, flapper, supply line, and a rusted fill valve can all lead to lead in your toilet tank.

Here Are The Various Causes Of Tank Leakage:

Faulty Flapper

A toilet tank holds water and supplies it to the toilet bowl when flushing, the work of a flapper is to initiate the flushing. For instance, when you flush, the flapper is lifted, and water enters the toilet. After flushing, the flapper seals up back to allow for the tank refill.

If the flapper is damaged, water will always leak from the tank into the toilet bowl. A solution to this is to replace the flapper; you can also try shifting the flapper back in place if it swayed away from its original point.

Cracked Supply Line

Water enters the toilet tank through a component of the tank called a cold-water supply line. This component prevents air from entering into and out of the tank. When water with high pressure passes into the tank it can result in the cracking of the supply line.

Repairing of a cracked supply line should be done by a professional plumber. However, make sure you switch off all water supplies in the toilet or bathroom,

Cracked Tank

when you notice a great bank of water around the base of your toilet tank, you should know that the cause is probably a broken tank. To properly fix this, you might need to install a new one because just patching the cracks won’t do.

A Toilet Leaking From The Handle

Water leaks around toilet handle due to the following reasons:

  • Toilet tank has been overfilled by water
  • A spray of water from the overflow tube
  • Faulty toilet handle

To fix this issue, empty the toilet tank by flushing, then refill and note if the water level is higher than it ought to. The water level shouldn’t get to the handle level; if this is the case, do the following:

  • Adjust the float valve a bit by locating and bending the rod connected to the valve
  • Screw the float valve in the clockwise direction.

If the leakage is caused by the spraying of water by the overflow tube, simply pull in the smaller tube gently into the larger overflow tube and fix them back in place.

For a faulty toilet handle, replace it immediately.

Final Words

If you notice that your toilet is leaking a blue fluid, it shows that the water contains a substantial amount of copper.

The use of disinfectant is another possible cause of blue fluid. Usually, these occurrences are not harmful, but it is advisable to seek a plumber’s advice if you notice them in your house.
