What our customer has to say

A gas leak is confirmed by testing, not by smell

Smell tells you something may be wrong. It does not tell you where the gas is escaping, how fast, or whether the problem is the line or an appliance.

Those answers come from a pressure test at the meter, followed by systematic checking of the system. Until that is done, nobody can honestly tell you what the repair involves.

How we find a gas leak, step by step

Gas leak detection is a process of elimination carried out in a set order. It is not guesswork, and it is not a matter of sniffing around appliances.

Each stage narrows the possibilities before the next one begins:

Isolate at the meter and pressure test the line to confirm gas is escaping
Measure the rate of loss, which indicates how significant the leak is
Section the system to separate the fixed line from the appliances
Test joints and connections with electronic detection and leak solution
Confirm the source, repair it, then re-test the whole system before restoring gas

If you suspect a gas leak in Wanneroo, leave the property and call 0400 838 622 from outside.

Where gas leaks actually occur

Gas rarely escapes through the middle of a sound pipe. It escapes at the points where the system joins together, moves, or has been worked on.

That is why sectioning the system matters. Separating the fixed line from the appliances usually halves the search area in the first few minutes.

Wanneroo homeowners choose Sureflow because the process is methodical:

The common failure points we test first

Experience narrows this down quickly. Certain connections fail far more often than others, and they get checked before anyone starts lifting floorboards.

The usual suspects:

Appliance connection points, particularly flexible bayonet hoses
Threaded joints where a fitting has loosened or the seal has aged
Isolation valves at appliances and at the meter
Corroded sections of buried or external pipework
Recent alterations, where a previous job was not tested properly

We repair the issue at its source and check whether anything else nearby is worth monitoring while we are there. Where relevant, we also carry out a complimentary whole-house plumbing inspection so you have a clearer picture of your plumbing overall.

Frequently asked questions about gas leak detection in Wanneroo

Clear answers to the questions homeowners ask most, so you can understand what to expect, how issues are handled, and when to take the next step with confidence.

How do you test for a gas leak?

We isolate at the meter and pressure test the line, which confirms whether gas is escaping and at what rate.

From there the system is sectioned to separate the fixed pipework from the appliances, then joints and connections are checked with electronic detection equipment and leak solution until the source is confirmed.

How long does gas leak detection take?

A straightforward leak at an accessible connection is often found within the first hour.

Where the system is larger, partly buried, or has been altered over the years, it takes longer because more sectioning is involved. We will tell you what we are finding as we go rather than leaving you guessing.

Do I have to turn the gas off before you arrive?

If you can smell gas, yes. Turn the meter lever to horizontal if you can reach it safely from outside, leave the property, and call us from outside.

If there is no smell and you are booking a test because of a high bill or a suspicion, leave the gas on. We need the system pressurised to test it.

Can you detect a leak in a buried gas line?

Yes. Pressure testing tells us the buried section is losing gas, and electronic detection narrows the location before anything is excavated.

That means one targeted dig rather than trenching the whole run.

What if the leak turns out to be in an appliance?

That is a common outcome, and it is good news, because appliance connections are usually the most accessible part of the system.

We can repair or replace the connection, or service the appliance where the fault is internal. Where an appliance is beyond safe repair we will say so plainly.

Will you need to open up walls or floors?

Only if the leak is in a concealed section, and only after testing has narrowed it to a specific area.

Most leaks are found at accessible connections, appliances or valves. Sectioning the system first is exactly what avoids unnecessary opening up.

Can you repair the leak on the same visit?

Usually, yes. Our vehicles carry the fittings and equipment needed for the majority of gas repairs.

Where a specific part or appliance component is required, we leave the system safely isolated, explain what is needed, and book the return at a time that suits you.

Do you re-test after the repair?

Always. A repair is not finished until the whole system has been pressure tested again and holds.

Gas is only restored once that test passes. Anything less would be leaving you to find out the hard way.

Are you licensed for gas work?

Yes. Sureflow holds gas licence GF18902 alongside plumbers licence PL9896.

Gas work in WA must be carried out by a licensed gas fitter, and it is worth checking the licence number of anyone you engage for gas work on any job.

What are the signs of a gas leak?

The obvious one is the rotten egg or sulphur smell, which comes from mercaptan added to natural gas so leaks can be detected.

Less obvious signs include a hissing sound near pipework or appliances, a gas bill climbing with no change in usage, dying vegetation above a buried line, and a yellow rather than blue burner flame.

My gas bill has jumped. Could that be a leak?

It can be. A leak too small to smell can still be significant enough to show up on a bill over a quarter.

A pressure test settles it quickly. If the line holds, the increase is usage or tariff related; if it does not, you have found something worth fixing.

Is a small gas leak still dangerous?

Yes. Gas accumulates in enclosed spaces, so a slow leak in a confined cupboard or subfloor can build to a hazardous concentration over time.

Size determines urgency, not whether it matters. Any confirmed leak should be repaired.

How often do gas systems need testing?

There is no fixed requirement for domestic systems, but a test is worth doing when you buy a property, after any alteration to the gas system, and if anything about your usage or bills changes unexpectedly.

Appliances themselves are generally recommended for service every two years, which is also when combustion issues get picked up.

Do I need to know where the leak is before I call?

No. We will take care of that.

Call 0400 838 622 and we will test the system, confirm exactly where the gas is escaping, and handle the repair from there. You do not need to diagnose anything before you pick up the phone.

Will you explain what you found?

Yes. We walk you through what the testing showed, where the gas was escaping, and what the repair involved.

You should never be left guessing about work carried out on your own gas system.

Do you attend rental properties in Wanneroo?

Yes. We attend rental and strata properties across Wanneroo and the wider northern suburbs.

Safety comes first regardless of who owns the property. Call 0400 838 622 and we will let you know what we can do and how approvals are best handled.

Our wider service area runs from Two Rocks in the north down to Scarborough, and inland to Landsdale.

The standards behind every Sureflow visit

Plumbing is easier to deal with when you know exactly what’s happening.

Each visit is structured around practical assessment, straightforward advice, and work that suits the condition of the system in front of us. These standards help keep repairs predictable, decisions informed, and homes protected as issues are resolved.

Clear explanations before work begins

Understanding what has changed within the plumbing system makes decisions easier to make. The issue is explained first, along with the available options. This removes uncertainty before any repair is carried out.

Practical advice on what needs priority

Some faults require immediate attention, while others can be planned over time. Advice is provided in a way that helps repairs happen in the right order. That structure reduces pressure when unexpected problems appear. We focus on getting it fixed properly, not just quickly.

Recommendations based on what’s actually there

Every property is different, and repairs should reflect what is actually present on-site. Solutions are shaped by the condition of existing pipework and fixtures. This helps avoid unnecessary replacement work.

Care taken while working inside the home

Plumbing repairs take place in lived-in spaces, not empty work zones. Attention to surrounding areas helps keep disruption to a minimum. The condition of the home remains part of the job.

Early notice of future potential issues

Some plumbing issues develop gradually rather than all at once. Where relevant, potential future concerns are identified during the visit. This allows maintenance decisions to happen earlier and with more clarity.

Support when timing and urgency matters

Unexpected plumbing problems can escalate quickly without early assessment. Prompt guidance helps stabilise the situation before further damage develops. This keeps urgent issues more manageable across Perth northern homes.
