How to Find Your Water Meter (and Why You Should Do It Today)

If a pipe bursts, the difference between a mopped-up floor and a insurance claim is usually how quickly someone turned the water off.

That means knowing where your water meter is before it happens — not searching the front yard with a torch at 2am while water pours through the ceiling.

It takes five minutes. Do it today.

Where to look

In New South Wales, the water meter is almost always at the front boundary of the property, near the footpath or the driveway, on the side closest to the street.

Look for:

• A rectangular plastic or metal cover set into the ground, often marked "WATER"
• A small concrete pit with a lid
• On older properties, a meter in a green or black box mounted low on a front fence

If you can't see it, check:

• Under overgrown grass or garden bed edging along the front boundary
• Behind the letterbox
• In units and townhouses, in a common meter cupboard or bank of meters near the entrance — yours will be numbered to match your unit

If you genuinely cannot find it, Sydney Water can tell you where it is on their records.

Turning the water off

Next to the meter there's an isolation tap — sometimes called a stop tap or stop valve. It's on the house side of the meter.

Turn it clockwise until it stops. That's it. Water to the whole property is off.

Test it now, while nothing is wrong. Two reasons:

1. You'll know for certain you've found the right tap.
2. Meter taps seize with age and disuse. Finding out yours is seized during an actual emergency is a genuinely bad moment — and it's a five-minute job for a plumber to replace beforehand.

After testing, turn it back on slowly. Opening it fast sends a pressure surge through the house that can cause water hammer or, on older pipework, a burst.

Using the meter to find a hidden leak

This is the most useful trick your water meter offers, and it costs nothing.

1. Turn off every tap and water-using appliance in the house — including the washing machine, dishwasher and any irrigation.
2. Go and look at the meter. Note the reading, including the small dial or the last digits.
3. Wait 30 minutes without using any water.
4. Check it again.

If the reading has moved, you have a leak somewhere on your side of the meter. There's no other explanation.

Many modern meters have a small red or black leak indicator dial that spins with even a tiny flow. If that's turning with everything off, you're losing water.

What a hidden leak actually costs you

People underestimate this badly:

• A leaking toilet cistern can waste over 200 litres a day silently
• A dripping tap wastes around 20,000 litres a year
• An underground supply line leak can run for months before anything surfaces

The first sign is usually a water bill that has jumped for no apparent reason. If that's happened to you, do the meter test before you do anything else.

If the meter says you have a leak

The next question is where, and that's harder — most concealed leaks are under a slab, inside a wall cavity, or in a buried supply line.

Guessing is expensive. The point of proper leak detection using acoustic equipment and thermal imaging is that we open up one specific spot rather than four exploratory holes. The difference in reinstatement cost is usually larger than the detection itself.

A short checklist worth keeping

• Know where your meter is. Show everyone else in the house.
• Test the isolation tap once a year so you know it turns.
• Do the 30-minute leak test if a bill looks wrong.
• In an emergency: water off at the meter, power off at the switchboard if water is near electrics, photograph everything before you clean up, then call a plumber.

We cover the Hills District, Hornsby Shire and the Upper North Shore 24 hours a day for burst pipes and major leaks. If you're standing in water right now, turn it off at the meter and call us — we'll talk you through the rest while we're on the way.
