Sometimes the cause is obvious. You may be able to see water dripping from a tap connection or pooling underneath a sink.
Other leaks are much harder to identify. A damp patch on a ceiling, for example, tells you where the water has appeared, but not necessarily where the leak started.
So when can you investigate the problem yourself, and when is it time to call a plumber?
Start by trying to identify where the water is coming from
If it is safe to do so, look around the affected area before assuming the source.
Check visible pipework, taps, toilets, sinks and nearby fittings for moisture.
Remember that water can travel along pipes, floors and other surfaces before becoming visible. The wettest area is not always the exact source.
Know where your water shut off valve is
Every homeowner should know how to isolate the water supply.
If a pipe suddenly begins leaking heavily, turning off the water can help limit further damage while you arrange a repair.
If water is close to electrical equipment, sockets or wiring, avoid taking unnecessary risks.
When might you need a plumber?
Calling a plumber is sensible when you cannot confidently identify the cause, the leak keeps returning or the repair requires plumbing fittings or pipework to be removed.
Other warning signs include:
- Water appearing through a ceiling
- Persistent damp around plumbing
- Water pooling beneath flooring or units
- A leaking pipe or fitting
- A toilet that continually runs
- Repeated loss of water pressure
- A leak that returns after an attempted repair
The priority is not simply stopping the visible drip. The underlying cause needs to be found.
For professional fault finding and repairs, see the existing Leaks and Plumbing Repairs service page.
Why small leaks should not be ignored
A slow leak may not look urgent, but water can gradually damage cupboards, flooring, ceilings and surrounding materials.
Moisture can also spread beyond the area where you first notice it.
Getting the source identified early can prevent a small plumbing problem from becoming a larger repair.
What information should you give your plumber?
When you get in touch, explain:
- Where you can see the water
- When you first noticed it
- Whether the leak is constant or intermittent
- Whether anything makes it worse
- Whether you have isolated the water
- Any other changes you have noticed, such as lower pressure
Photos can also be useful when discussing the problem before a visit.
