How to check your water service for leaks

New Meter – This is a very short test (it takes no more than six steps).

  • Make sure that you know what all the dials on the water meter measure (see above diagram).
  • Confirm that all water taps both within and outside the house (garden area, backyard etc) are turned off. Moreover, make sure that the toilets, bathrooms, dishwashers, water appliances such as water machines are not being used at all.
  • Monitor the reading on the meter for the first few moments. Record, even slight movements, in ‘tell-tale’ wheel (refer to the diagram). To gauge the degree of a leak, start with noting the reading, wait for ten minutes and then take another final one. Record all details on the dial.
  • Deduct initial reading from last (final) reading. Ensure that you are writing all your readings in litters and not kiloliters.
  • Multiply your readings by six to get the litters reading gone in an hour

  • Initial reading: 1234, 567.8 litres
  • Final reading: 1234, 574.8 litres
  • Total usage: 7.0 litres x 6 = 42 litres/hour
  • 42 x 24 = 1,008 litres/day
  • 1,008 x 90 = 90,720 litres/quarterly billing period (approx).

Following are examples of how to read the two most common water meters.

When using other meters – Six point extended test

  • Ensure that you are aware of all the dials on the water meter (as shown above).
  • Set up a designated time when there will be no use of water. For example, you can set any time in the night when the whole house is sleeping or when everyone is off to work.
  • All taps should be closed. Water appliances such as dishwater, washing machines, toilets, bathrooms all should not be under any use.
  • To determine the amount of leak, take an initial reading and wait for twelve hours. After this, take another reading (final reading). Keep record of all the dial readings.
  • Deduct the initial reading from the final one to determine the amount of liters that were used. Ensure that all recordings are in liters and not kiloliters.
  • Divide by the number of hours to determine the number of litres lost per hour.
