Fixing A Leaking Cistern

A leaking toilet is not only a pain in its own right, but it may be wasting up to 600 liters of water a day.

This could be costing you dearly, depending on how you are billed for your water.

In addition to this, you face a potentially expensive repair visit from a plumber.

But you should be able to fix some of the more basic problems for yourself, here’s how.

HOW TO CHECK IF THERE IS A LEAK FROM THE PAN TO THE CISTERN

This may be hard to diagnose initially. However, it should be possible to check if there is water leaking out, when the toilet isn’t in use.

You can also check by drying the toilet bowl half an hour after it has been flushed and then leaving bathroom paper on the rear of the toilet.

Let it stay there overnight and don’t disturb it – or for at least a good few hours (we advise no less than three).

If it is torn or wet after this time has elapsed, then your toilet has a leak!

TOILETS WITH BUTTONS

When the cup on your toilet with buttons ‘runneth over’, sometimes it is simply down to limescale getting inside the works.

It might be fixed by doing something as easy as tapping the button down firmly a couple of times. Alternatively, try holding both buttons down. This will give the cistern the chance to drain properly.

If this fails to help, then you may need to get a new flusher.

WHEN A TOILET LEAKS ONTO THE GROUND

When a close coupled toilet is leaking onto the bathroom floor, then both toilet and tank might require a re-fit, at exactly a 90 degree angle.

When there is water coming from the tank and it is a low type of toilet, then the likely culprit is the pipe sealing into the cistern.

Detect the source easily, by drying the toilet thoroughly with a cloth and then looking to see where the leak is on the connecting parts.

Does it only leak when you flush it? If so, it’s probably the coupling for the toilet waste pipe, where the leak is.

IF THE TOILET CISTERN OVERFLOW LEAKS

If you have an old school style high up toilet cistern, which is has water dripping from it, all you have to do is adjust the positioning of the float inside it. If the float is broken, it can be easily replaced.
