Leak detection in Sale
Think you have a hidden water leak in Sale? How to run a meter test, the signs in walls and slab floors, what a leak detection visit involves and price bands.
To check a Sale home for a hidden leak, turn off every tap and water-using appliance, read the water meter, wait at least half an hour without using any water, and read it again. If the numbers have moved, water is escaping somewhere between the meter and the fixtures. A leak detection visit then narrows down where, using pressure testing, listening equipment or a thermal camera, so that only the right patch of wall or floor is opened.
Your enquiry goes to an independent local plumbing business, not to staff of this site, and that business traces and quotes the leak in its own name. The about page explains the arrangement.
How do you do a water meter test?
The meter test is the quickest way to prove a leak exists, and you can do it yourself before anyone visits.
- Turn off every tap inside and outside, and make sure the dishwasher, washing machine and irrigation are not running.
- Check that no toilet is refilling.
- Find the water meter, usually in a box near the front boundary, and write down every number on it, or take a photo.
- Many meters also have a small dial or star that turns at very low flow. Watch it for a minute.
- Wait at least 30 minutes without using any water, then read the meter again.
- If the reading has changed, there is a leak. To narrow it down, turn off the stop tap under each toilet and repeat the test. If the meter stops moving, a cistern is the cause.
Some homes have a separate valve on the cold supply to the hot water system. Turning that off and testing again tells you whether the leak is on the hot side or the cold side, which saves time on the visit.
What are the signs of a hidden leak?
- A damp or swollen skirting board, or paint that bubbles low on a wall.
- A warm patch on a tiled or concrete slab floor, which can mean a hot water pipe is leaking under it.
- A musty smell or mould in a cupboard, wardrobe or behind the toilet.
- The sound of running water when everything is turned off.
- A water bill well above the same quarter last year with no change in household use.
- A soggy patch of lawn or garden that never dries out, between the meter and the house.
- Lower pressure at some taps than usual.
One sign alone can have another cause, such as condensation or a blocked gutter. Two or more together, plus a meter that moves, is a strong case for a leak detection visit.
Where do hidden leaks usually turn up?
| Location | Typical clue | What usually follows |
|---|---|---|
| Hot water pipe in a slab | Warm spot on the floor, hot water unit running more often | Locate the leak, then reroute or repair the pipe |
| Pipe or fitting behind a shower wall | Damp skirting in the next room, loose tiles | Repair the fitting, then a waterproofing check |
| Toilet cistern | Meter stops when the toilet stop tap is closed, water trickling into the bowl | Cistern repair, see the tap and toilet repairs page |
| Underground service pipe, meter to house | Wet ground or green strip in the yard | Locate and repair or replace the pipe |
| Garden irrigation line | Meter moves only when the irrigation valve is open | Repair the line or the valve |
| The meter or the pipe before it | Water around the meter box | Report it to Gippsland Water |
What if the leak is at the meter or in the street?
Gippsland Water repairs its own pipes outside the property boundary, and its fault, leak or burst form lists water meter leak and water leak as fault types, and it asks people to report problems even when they are on public land. If water is pooling around the meter itself, or rising from the nature strip or footpath, report it there before booking a plumber. Pipes inside your boundary are yours to repair, and a plumber can confirm which side a leak is on.
What happens on a leak detection visit?
A plumber who traces leaks will usually:
- Repeat the meter test to confirm the leak and how fast it runs.
- Isolate sections of the pipework, such as the hot side, the cold side or a single branch, to find which one is losing water.
- Pressure test the isolated section and watch the gauge.
- Use acoustic listening gear to hear the leak through a floor or wall.
- Use a thermal camera or moisture meter to map warm or damp areas.
- Mark the likely position and explain the options before anything is cut.
A careful plumber will not start cutting into walls or lifting tiles until the position has been narrowed down, and will tell you plainly if the evidence points to a fault on Gippsland Water’s side. If the leak cannot be found on the day, ask for what was ruled out in writing so the next step is not a repeat.
If your meter test has already shown movement, you can book a leak detection visit through the enquiry form and include the two readings and the time between them.
How much does leak detection cost?
hipages’ 2026 national averages put leak detection at $168 to $400, according to its leak detection cost guide, updated in January 2026. That covers finding the leak. The repair is priced separately once the plumber knows where it is and what it involves, and labour for that work sits at $90 to $148 per hour in The Quote Yard’s 2026 Gippsland table. The Sale plumbing cost guide lists the other common jobs.
The price climbs with the size of the house, how many sections need testing, whether thermal or tracer equipment is needed, and how hard the pipe is to reach.
Why can a leak go unnoticed in sandy ground?
In sandy soil, water from a leaking underground pipe can soak straight down instead of showing as a wet patch on the surface. Loch Sport, between the Ninety Mile Beach and Lake Victoria, sits on sandy ground, so a leak there may show up first as a meter that keeps turning or a larger bill. The Loch Sport area page covers local conditions there. On firmer ground, the same leak is more likely to leave a soft, green strip in the yard.
What if you smell gas instead?
Leak detection on this page means water. A gas smell is a different matter: leave the area, do not use light switches, appliances or anything that could spark, keep flames away, and get help from outside the building. Do not try to trace a gas leak yourself.
When is a leak a burst instead?
If water is spraying or pouring from a pipe you can see, it is a burst, not a hidden leak, and the first step is to turn the water off at the meter. The burst pipe repair page covers what to do next.
Next step
In the enquiry, give both meter readings and the time between them, say whether the meter stopped when you closed the toilet stop taps or the hot water valve, and list any damp, warm or mouldy spots with a photo of each. Mention whether the floor is a slab or raised timber and roughly how old the house is. Then send your leak detection enquiry.
Frequently asked questions
- Will Gippsland Water reduce my bill if a hidden leak caused it?
Ask Gippsland Water directly whether it offers any allowance for a concealed leak and what it needs from you. Keep the plumber's invoice and written findings showing where the leak was and when it was repaired, because any request will rely on that evidence.
- Can a leak detection plumber find a leak without damaging anything?
Finding it usually needs no damage at all, because the testing works through floors and walls. Fixing it is another matter: a pipe inside a slab or wall has to be reached, either by opening a small section or by running a new pipe on a different path.
- Does home insurance cover finding a hidden leak?
Some policies pay part of the cost of locating a leak that has caused damage, and some exclude slow leaks entirely. Read the policy wording or ask your insurer before booking, and photograph any damage first so the claim has a record.
- Can a dripping tap or hot water relief valve make the meter move?
Yes. A steady drip or a relief valve running into its drain uses water like any other outlet, so fix or turn those off before the meter test. Otherwise the test shows water use that is visible and simple to repair, rather than a hidden leak.
- How fast can a small leak add up?
A slow leak running day and night adds up over a billing quarter, which is why a bill jump is often the first clue. Read the meter at the same time on two mornings with nothing running overnight to get a rough daily loss for the plumber.
