Toilet symptom

Toilet keeps running?

A toilet that continues to fill or run into the pan is usually best described through its cistern behaviour. It is not the same starting point as a blocked toilet with rising water.

Listen for the patternConstant, after flushing or intermittent?
Identify the pattern

Where is the water going?

Into the pan

Water can be heard or seen continuing to enter the bowl after the flush.

Cistern keeps filling

The cistern does not settle, refills repeatedly or takes an unusually long time.

Noisy or intermittent

The toilet is quiet sometimes but starts running or humming without a full flush.

Describe when it happens

What changed after the last flush?

01

Flush the toilet only if it is safe and the water level is normal.

02

Notice whether the sound stops, continues or returns later.

03

Share whether the handle, button, cistern or water level looks different.

Avoid making it worse

Keep the description practical

If water is running continuously, stop using the toilet and limit the source if you know how to do so safely.

Do not force the flush control or dismantle the cistern to find a part.

If water is escaping around the toilet, mention the location of the leak as well as the running sound.

What to send in the enquiry

Cistern details are useful

Photo or short description

This is a toilet repair symptom.

Use Toilet Repair for running water, filling and flush mechanism faults. Use Blocked Toilet only when the main issue is rising water, overflow or slow drainage caused by a blockage.
