If your cold water tank is leaking

What to do if your cold water tank is leaking

If you think your cold water tank may be leaking, prevent further damage by following these steps:

  1. Make sure the mains water is turned off at the stopcock
  2. Turn on all the cold water taps and flush the toilet several times. This will empty the cold water storage tank and stop the flow of water
  3. If you have an open fire burning you should let it burn out and do not light it again until the burst pipe has been fixed
  4. Turn off oil or gas heating systems and do not use again until they have been checked
  5. Do not use the water heater as this may cause the hot cylinder to collapse
  6. Do not turn on the water supply at the stopcock until the burst pipe has been repaired
  7. If the water has come into contact with electrical fittings the electricity should be turned off at the mains
  8. If you are going to be away from your home for more than a day or two during cold weather you should drain down the cold water system as described above.
