A leaky tap can be frustrating to deal with. They can range from an occasional, light drip to a stronger, more persistent leak. Finding the cause of that leak can be just as frustrating.

But it doesn’t have to be. You may just simply be diagnosing the wrong cause of the issue.

In this post we give you a comprehensive list of all the reasons why your tap might be leaking, to save you time and energy.

The Washer:

The most common cause of tap leaks.

This is the small rubber or leather ring in your tap that presses down on the end of the water pipe to stop the flow of water. Over time they can corrode, get damaged by use over time or simply may not have been installed properly in the first place.

The O-Ring:

This is a part installed in your tap handles to create a waterproof seal. If these get damaged, or come loose, it will cause leaking near the handle of your tap.

The Cartridge:

Your cartridge is responsible for the flow and temperature of your water and is one of the most important parts that make up your tap.

It can get damaged either due to accidents or wear and tear over time. The cartridge is easy to replace, as long as you have a proper knowledge of how a tap works – so if you don’t have the knowledge:

Call a plumber.

The Valve Seat:

A very vulnerable part of your tap that resides where the spout meets the tap. This part can get damaged by mineral build up, or just general wear and tear over time.

With the right tools, a leaky tap due to a valve seat can be fixed easily.

Loose parts:

Perhaps your tap is leaky simply because the parts within your tap is loose. Try tightening the pieces within your tap, such as the washers and the O-ring.

If the problem persists, replace them. If the leak still doesn’t go away, it’s time to consider other causes, or simply call a plumber.

Excessive water pressure:

High water pressure could be the cause of that leaky tap. Excessively high-water pressure restricts water from effectively flowing to and from it’s destination. This causes pipes to get backed up with water.

This water then tries to find it’s way out of the pipes, leading to leaks from your taps.

Pipe issues:

High water pressure could also be a sign of a pipe issue. Corrosion, cracks or damage from tree roots can cause water pressure to fluctuate, leading to occasional drips.

While this is an unlikely source of leaky taps, if you suspect you have pipe issues, look out for these other tell-tale signs: strange smells, weird coloured water, significantly large leaks.

Tap types:

Some tap types are simply more prone to leaking, such as ball-type taps. These taps are controlled by a metal ball that determines the level of water and the water pressure.
