How to check your water service for leaks

New Meter - Six point short test

* Make sure that you know what all the dials on the water meter measure (see above diagram).
* Ensure that all taps within the house and garden (not including the main stop-tap) are turned-off, and that all water appliances, including toilets, dishwashers and washing machines, are NOT being used.
* Examine the meter for a few minutes and note any movement in the "tell-tale" wheel (see above diagram).
* To determine the extent of a leak, take a start reading, wait 10 minutes, then take a final reading. Don't forget to read all the dials.
* Subtract the start reading from the final reading. Be sure to write your answer in litres and not kilolitres.
* Multiply by six to determine the amount of litres lost per hour.

If a leak is detected arrange for us to call and trace the leak

Example:
Start 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).

Other Meters - Six point extended test

* Make sure that you know what all the dials on the water meter measure (see above).
* Allocate a time when water will not be used :eg when the house is unoccupied whilst people are at work/ overnight.
* Ensure that all taps within the house and garden (not including the main stop-tap) are turned-off, and that all water appliances, including toilets, dishwashers and washing machines, are not being used.
* To determine the extent of the leak, take a start reading, wait 12 hours, then take a final reading. Don't forget to read all the dials.
* Subtract the start reading from the final reading to arrive at the number of litres used. Be sure to write your answer in litres and not kilolitres.
* Divide by the number of hours to determine the number of litres lost per hour.

If a leak is detected arrange for us to call and trace the leak

Example:

Start reading: 1234, 567.8 litres
Final reading: 1234, 667.8 litres
100.0 litres / 12 hours = 8.3 litres/hour
Total usage: 8.3 x 24 = 200 litres/day
200 x 90 = 18,000 litres/quarterly billing period (approx).
