Toilet Not Flushing

Does this sound like your situation?

What can cause toilet not flushing?

There is rarely one universal cause. Common possibilities range from a local fixture problem to a deeper issue in the pipework, drainage or hot water system. The safest approach is to look for visible clues, avoid dismantling anything hazardous, and escalate quickly if water, gas, sewage or electrical equipment is involved.

Safe checks you can make first

• Check whether the problem affects one fixture or several.
• Look for active leaking, unusual smells, noises, discolouration or water damage.
• Note when the problem started and whether it is getting worse.
• If water is escaping rapidly and you can safely access the main shut-off, turn it off.

When should you call a plumber?

Call when the issue is persistent, recurring, spreading, causing damage, or requires work on regulated plumbing or gas systems. A useful first description includes the affected fixture, symptoms, duration and your location.

DIY checklist

DIY checks for a toilet that will not flush. These checks are intended to help you understand the symptoms without taking apart regulated or hazardous equipment.

1. Make sure the cistern is actually filling after a flush.
2. Check whether the flush button or handle feels loose, stuck or unusually light.
3. If the bowl is rising toward the rim, stop flushing and avoid adding more water.
4. For a minor visible obstruction, a toilet plunger may help; use steady pressure rather than repeated forceful pumping.
