Water Bills & Meters
Reading the meter to prove a leak, what an unexplained jump actually costs you per day, and the evidence a water company wants before it grants an allowance.
How to Read Your Water Meter to Find a Leak
The two-reading test done properly, including the digits your water company tells you to ignore, and the arithmetic that turns the gap into litres per day.
Water Bill Doubled? What to Check, in Order
Most doubled water bills are a billing artefact or a change in usage, not a leak. Work through them in this order before anyone lifts a slab looking for a pipe.
Water Bill Too High: Is It a Leak or Your Usage?
A leak and a change in habits produce the same bill and completely different meter behaviour. Three tests separate them, and you can run all three yourself.
What a Leak Costs You Per Day, and How to Work It Out
A method, not a headline figure. Measure the loss at your own meter, apply your own metered rate, and get the daily cost of leaving a leak running.
The Evidence You Need for a Leak Allowance Claim
A leak allowance is decided on paperwork: the repair invoice, meter readings from before, during and after, and the repair date. Collect them in order.
Unexplained Increase in Water Usage: How to Trace It
A structured elimination for metered usage that has risen with no visible cause: baseline overnight, isolate at the stop valve, then work branch by branch.
