A Leaking Toilet Starts As A Slow Drip But Will Get Annoying Fast


Leaking toilet issues are frequently heard but seldom seen. The sound of a toilet cistern turning on and off at night as it’s leaking is one of the most sleep depriving, annoying features of a leaking toilet.

A leaking toilet we can all agree is not an emergency but it will not go away ever.

A leaking and malfunctioning toilet cistern are generally one of four problems:

  • slow filling toilet cistern
  • a continuously running toilet cistern
  • a non-flushing toilet
  • a broken cistern tap

There can be other obscure issues as well, but these are the most common problems we run across and likely to be what we will need to repair for you.

Common Questions About Toilet Repairs

Learn To Identify Parts Of Your Cistern
With so many toilets and cisterns now available in Australia, we cannot identify them all. But in reality, they all operate the same.
The photo on the right identifies the two main valves inside every toilet cistern. These valves exist in every cistern in one way or another.

Not every cistern has a separate overflow with some having the overflow built into the flush valve. Major issues with these valves are:

  • Water Inlet Valve – this valve is always a float valve that automatically lets water into the cistern and can be installed on either the left or right side of the cistern. It is connected to an external cistern tap underneath the cistern usually with a flexihose but with chrome copper in older homes.
  • Dual Flush Valve – this valve is what releases water as a half flush or a full flush into the toilet bowl when you push the buttons on the lid to flush the toilet.
  • Overflow – obviously this is not a valve but ensures that water levels inside the cistern can never get too high and is a safety device to let excess water inside the cistern overflow directly into the toilet bowl.
Is Your Toilet Cistern Slow To Fill?
Frequently this will show up when toilet usage is at its morning peak. Usually, the cistern is so slow to fill that it cannot be flushed. Typically this is highlighting a faulty water inlet valve, but it can also be the cistern tap or even a problem in the water supply.
Is Water Constantly Running Into Your Toilet Bowl?
Constant running water can be the ultimate annoyance. Often this is why your water inlet valve is turning on and off all through the night. As the water level in the cistern drops, so the valve activates.

The water running into the toilet bowl is either from a faulty dual flush valve leaking or a faulty water inlet valve. Often it can be both valves is faulty and is leaking. To put it in perspective a toilet cistern can leak around 30 litres an hour which is 720 litres a day or 5040 litres a week which will cost you $19.66 a week.

Is Your Toilet Not Flushing Away The Contents Of The Toilet Bowl?
We all know this can be embarrassing especially if you have visitors as it results in an unsightly smelly toilet. Generally what happens every user of the toilet is either multiple flushing and constantly waiting for the cistern to fill.

A weak or low flush of water from the cistern can once again be both valves being faulty. It is a faulty dual flush valve failing to operate correctly. It can also be a faulty water inlet valve being extremely slow to let water in or the water levels are set incorrectly. Often if not repaired you will end up with a blocked toilet.
