If you have a leak on your supply pipe it is your responsibility to fix. As ground expands and contracts throughout the seasons, water pipes can pull apart or crack. Corrosion can be caused by the chemical properties of the soil, especially on iron pipes.   

If you suspect a leak, there are simple steps you can take to check. If you have a metre, check the dials are not moving when everything is turned off. If they are moving, its quite possible that you have a water leak. Check for unexpected overnight usage or leakage. Take a metre reading at night and then again in the morning. Compare the readings. Other give away signs are damp patches in the garden, sudden drop in water pressure, higher water bills or unusual sounds of hissing or running water.

Damp patch?

If you have a damp patch in the garden or one area of the lawn that that is always green, you could have a water leak.

Hear running water?

Can you hear water running into a drain when no water is being used at your property or can you hear hissing? This might suggest a water leak.

Low water pressure?

Low water pressure, high meter readings and bills all suggest a water leak.

Water meter readings

Check the dials on your water metre. If they are moving even when you are not using water or if there is a significant difference between night and morning, you could have a water leak.
