A concealed leak can sit under a driveway, beneath a slab or inside a wall and waste thousands of litres a day while nobody notices. You pay for all of it, because the meter records every litre drawn through it.
Signs of a Leak You Cannot See
Three places give a hidden leak away: the meter, the house and the yard. The common thread is a water bill that climbs without any change in how you live.
At the meter
the dial creeping or the numbers ticking over with every tap in the house shut off.
In the house
a stain spreading on a wall or ceiling, finishes that swell or lift, a musty smell, or a floor patch that feels warm underfoot.
In the yard
ground that stays soggy, or a strip of lawn growing greener than everything around it.
If the meter box itself is sitting full of water, that points to a problem at or around the meter, and the water utility handles it. Soggy ground with the dial sitting still usually means the utility's own pipe. Soggy ground while the dial ticks over means the draw is past the meter, on your property, and that's where we come in.
Water Bill Relief for a Hidden Leak
Yes, a concealed leak can earn a bill adjustment from Urban Utilities, but only when it meets their rules. The leak has to be hidden from view, sitting in the ground, in concrete or under the building, somewhere you could not reasonably have known about.
The conditions, in plain terms:
- the leak sits on your side of the meter, on private property;
- the repair is finished within a month of discovery;
- the account holder applies in writing, with a licensed plumber's invoice attached;
- leaking taps, toilet cisterns, hot water systems and other appliances never qualify, and neither do irrigation or outdoor water features.
Every pipe and fitting from the meter onto the property is yours to maintain, so the repair bill is yours either way. The adjustment is about the water the leak wasted, not the fixing of it. Don't wait for the utility to flag a high bill; read your own meter and act on what you see.
The Meter Test That Proves a Leak
Here is the test in one line: with every tap and water-using appliance off, record the meter, leave it no less than a full hour, then read it again. Any movement in the numbers or the dial means water is escaping.
The steps, in order:
- Turn off the hose, the washing machine, the dishwasher, any plumbed-in fridge and anything else that draws water.
- Photograph the meter numbers, red digits included, and leave the meter's own tap turned on.
- Use no water anywhere on the property for a full hour or longer.
- Read the meter again. A changed reading points to a leak, and a licensed plumber takes it from there.
A leak runs around the clock, so the test works best over a stretch when nothing in the house should be using water at all. If the reading has moved, our water pipe repairs page covers what the fix usually involves, and a burst that's flooding right now belongs on the burst pipe repairs page instead.
Where Hidden Leaks Sit in Hamilton
The suburb's two very different pockets hide leaks in two very different ways.
Up on the hill, the old villas around Annie Street were plumbed in galvanised iron. Renovations often bury those original runs behind newer wall linings, so a weeping joint can wet plaster for months before anything shows.
Down on the filled wharf flats, estuarine mud under the old wharf land keeps groundwater near the surface year-round. That makes soggy ground a poor clue on its own; the meter reading is what settles which side the loss sits on.
Ageing braided hoses add a third hiding spot, and our flexi hose replacement page covers why they fail. Where repeated leaks trace back to tired galvanised runs, repiping old pipes is the lasting answer.
How a Plumber Pinpoints a Hidden Leak
The method runs in a fixed order: confirm the leak at the meter, isolate sections of the line, pressure-test each section, then narrow the search before anything gets opened.
Isolate
valves close off one stretch of pipe at a time so each can be checked on its own.
Pressure-test
the section that loses pressure holds the leak.
Listen
running a hand or an ear along an exposed pipe or a wall picks up the sound of escaping water.
Moisture readings
checks in walls, floors and subfloor timber show where the water is travelling.
Nothing gets opened until the search has narrowed, which keeps the repair small and the reinstatement work to a minimum.

Leak Detection Questions From Hamilton Homes
Call (07) 3523 6484How do I check for a hidden water leak at home?
Shut off everything that draws water, then read your meter and come back after a full hour. If the numbers have moved while nothing was running, water is escaping somewhere past the meter. Photograph both readings, including the red digits, and call a licensed plumber to track it down.
Will Urban Utilities reduce my bill for a hidden leak?
Yes, when the leak fits the utility's concealed leak rules. The leak must be out of sight, sit on your side of the meter, be repaired within a month of discovery, and be backed by a licensed plumber's invoice. The utility decides each claim, and no fixed amount applies.
Do leaking taps or toilets count as concealed leaks?
No. Water lost through taps, toilet cisterns, hot water systems and other appliances is excluded from the relief rules, along with irrigation and outdoor water features. The owner wears that cost, which is why a dripping tap is worth fixing early rather than watching the bill climb.
How long do I have to repair a hidden leak?
The deadline is a month from when you find the leak. Access drives the repair time: where the pipe sits, what covers it, and how much lining or paving comes up. We give you a fixed quote before any work starts, so the scope is clear well inside the month.
Why is my water bill so high in Hamilton?
A leak is one common cause, and the meter test separates it from normal use. Turn off every tap and appliance, read the meter, wait, then read it again. Movement means water is escaping, and every litre the meter records is one you pay for.
