We've been having ongoing problems with bills for absurdly high water usage for a while now, from Watercare (Auckland). I've checked and there's no leak, so I'm suspicious that the meter itself isn't accurately measuring how much water we're using.
I've asked Watercare for the meter to be tested, but they appear to be really determined to prevent customers from actually getting it done. After speaking to two people at their call centre to make the request, I had to post them a form with a copy of my ID, and now I've had a further email asking if I really, really want the test to be done. If they don't find a discrepancy of over 3% there's a charge too; and every time I have contact with them it slides up - originally there was no charge, then it became $75, and now it's potentially $300. Furthermore I've 'heard' that whoever they get to perform the test could be incompetent, and that they've been known to turn up unannounced and then if nobody's around say they've done work when in fact they haven't. Marvellous.
So: Does anyone know how I can cheaply and accurately test the meter myself? If I can satisfy myself that the meter is definitely inaccurate I'll be happier to force the test through with Watercare.
By my reckoning I'd need to use at least 100 litres for any inaccuracy to be clearly visible on the meter readout. I can't exactly grab a 10 litre bucket and fill it up ten times, because the bucket itself isn't likely to be accurate - I need a way of accurately measuring a quantity of water. It seems like it should be a relatively simple task, but I can't think of how to do it. Any ideas, anyone?
