If water is running right now
Turn off the isolation valve if it is easy to reach — under the sink for a kitchen leak, or the main tap at the meter for anything larger. Then ring us.
That is the only thing we will ask you to do. Do not pull anything apart, move appliances or go into a roof space looking for the source. Finding it is our job and it is the part that is actually difficult.
Where filter systems leak
A water filter is a set of joins in your drinking water line, and every join is a place water can get out.

The housing seal
The O-ring between the cartridge housing and the cap is a consumable. It gets seated badly on a cartridge change, or it perishes, and the result is a slow weep down the side of the unit rather than a burst.
Push-fit connections
Quick connectors are fine when they are fully home and square. When they are not, they hold for months and then let go, usually while nobody is there.
The isolation valve on the cold feed
On the older Gosnells houses this valve is often the original one, and asking a decades-old valve to turn for the first time in twenty years is how a lot of small jobs become bigger ones. We look at it before we ask it to do anything.
The tap tail and the dedicated tap
The filtered tap has its own small line to it, and it passes through the benchtop. A weep there runs straight into the cabinet.
The drain connection on an RO system
Reverse osmosis sends water to the drain as part of how it works, and that connection is another join.
None of that means filters are trouble. It means a filter should be installed by somebody who will still be around when a seal needs replacing.
Leaks that have nothing to do with a filter
We find plenty of these while looking for the other kind.
Under-sink mixer tails
that have been weeping for long enough to swell the chipboard base.
Toilet cisterns
that run just slowly enough not to be heard.
Buried mains
between the meter and the house. This one is common in the old Gosnells townsite, where the service pipe is as old as the house and the ground it runs through has been dug up a few times since.
Hot water system relief lines
discharging more than they should.
Reticulation and bore lines
, which can put a lot of water into the ground without anything appearing at the surface. Worth ruling out before anyone opens a wall.
What makes Gosnells leaks their own job
The old townsite off Albany Highway and around the two stations is largely 1960s and 70s housing. It grew fast — about 7,500 people lived here in the 1950s and 9,504 by 1961 — and much of what went in then is still in the ground.

That matters for leak work in two ways. The service pipework has had decades to corrode or shift, and it has usually been patched at least once by somebody who is no longer available to explain what they did. So the pipe that looks like it should run in a straight line often does not.
The newer side of the suburb — the infill flats and apartments the council's growth figures point to, and the newer streets running toward Southern River — has modern pipework and a different problem. Leaks there are less about age and more about where things were routed during construction, and about shared walls and slabs where the water surfaces a long way from where it left the pipe.
At the 2016 Census 82.4% of Gosnells homes were separate houses, so most of our leak work is a standalone home with its own service run. Which era it belongs to changes how long the finding takes. We tell you what we think it is before we start, and the visit to form that opinion costs nothing.
How we go about it
1. You describe what you are seeing
Where the water is, when you noticed it, whether anything changed recently.
2. A licensed plumber comes out at no charge
He isolates sections, works from the visible evidence back toward the source, and rules things out in order rather than guessing.
3. You get told what it is and what it will take
In plain terms, with a written price before any repair work starts.
4. We fix it
Or, if the honest answer is that it is a smaller job than you feared, we tell you that instead.
Transparent pricing, no hidden costs. Monday to Friday, 7:00am to 4:00pm. Plumbing Licence 8396.
Why the cupboard damage matters more than the leak
A slow leak under a kitchen sink usually costs less to fix than the cabinet it has been sitting in.
Chipboard bases swell, and once the base has gone the sink support and the doors tend to follow. That is the reason we would rather look at a small damp patch now than a collapsed cabinet later, and the reason the call-out to look is free. There is nothing to lose by having it looked at while it is still small.
If the leak turns out to be at a filter system, we can deal with both in the same visit. Water filtration systems · Cartridge replacement
