Leaking or burst water pipes are not always visible and are often only discovered when an excessive water bill is received.
Damp areas, hissing sounds or the sound of water running are signs of a burst water pipe. Pipe burst are due to corrosion or old age, incorrect installation, excessive water pressure, inferior quality materials or temperature extremes. Frozen or over heated water weakens pipes and the pipe could burst.
Shut the water mains off. This will prevent further loss of water, and damage.
