Signs Of A Water Mains Leak On Your Property in the UK

Despite the common misconception that water leaks are conspicuous and easily noticeable, this is not always true, especially for minor leaks.


Here are several prominent clues that may suggest the presence of a water main leak:

High Water Bills

Frequently, people become aware of a water leak when they observe an unanticipated, substantial surge in their water bill. This sudden increase in water consumption is a clear indicator of a possible leak.

To confirm, monitor your water meter; if it's in motion or rapidly spinning during periods of non-usage, an unseen water leak is likely the cause.

Discoloured Water

Tap water appearing brown or discoloured is another potential indication of a water main supply pipe leak. A simple test involves allowing the water to flow for a few minutes.

If the discolouration persists, it's probable that a pipe leak has occurred, enabling water to intermingle with the adjacent soil.

Reduced Water Pressure

A decrease in water pressure can also hint at a leak in your water mains supply pipe. A logical inference is that a leak exists within the main water supply.

Similar to how a hosepipe kink affects water flow, reduced water volume and noticeable pressure drop from your taps often indicate a possible leak.

Surface Water Accumulation

Certain landscapes might naturally form puddles, particularly after heavy rain. However, standard puddles tend to dissipate rapidly.

If you come across puddles that remain persistent, this stands as a conspicuous sign of a potential water mains supply pipe leak.

What is a Water Mains Supply Pipe & Who is Responsible for a Water Mains Leak?

The water mains supply pipe is the dedicated pipeline that conveys your water supply from the water mains company's distribution network into your personal premises. Typically, this supply pipe and the associated responsibilities extend from your property's perimeter to the initial water connection point or internal shut-off valve.

Should a leak arise beyond your property limits, the water company assumes responsibility. Conversely, if the leak develops within your property boundaries, regrettably, you bear the responsibility for the cost of resolving the issue.
