What our customer has to say
A leaking drain and a blocked drain are not the same problem
A blockage announces itself. Water backs up, a gully overflows, and you know something is wrong within a day.
A leaking drain does the opposite. Waste water escapes into the ground through a crack or a failed joint, everything appears to drain normally, and nothing looks wrong until the damage shows up somewhere else entirely.
How a leaking drain gives itself away
Because there is no backup, the signs turn up around the property rather than at a fixture. Most people notice one of these long before they suspect the drainage.
Worth having checked if you notice:
- A patch of lawn or garden that stays green and lush through summer
- Ground that feels soft or spongy underfoot in one area
- A persistent smell outside near a gully or along a drain line
- Paving or a path that has started to sink or move
- Tree roots thriving in one spot with no obvious water source
If something in that list sounds familiar, call 0400 838 622 and we will take a look.

The camera settles it in minutes
You cannot diagnose a drain from the surface. A camera run through the line shows the condition of the pipe, where the fault is, and how far along it sits.
That is the difference between a repair aimed at the actual problem and a repeat visit every few months. You see the footage too, rather than taking our word for it.
Perth homeowners choose Sureflow because the process is straightforward:
- Your booking and arrival window is confirmed
- The issue is accessed onsite and we explain what is found
- A clear quote, where possible, is provided before starting the repair
- We complete the work neatly and test everything before we leave
Why drains fail, and why it is usually not sudden
Drainage is buried, gravity fed, and forgotten about for decades. When it fails, the cause has almost always been developing for years.
The common ones we find in Perth homes:
- Tree roots entering through a joint, then expanding and cracking it open
- Ground movement in sandy soil shifting pipe alignment over time
- Older clay or earthenware pipework cracking or collapsing with age
- Insufficient fall, so waste sits in the line instead of clearing
- Construction debris or a poor repair left in the line years earlier
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 leaking and blocked drains in Perth
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 I know if my drain is leaking rather than blocked?
A blockage shows up at the fixtures. Sinks drain slowly, a toilet struggles, or a gully overflows outside.
A leak shows up around the property instead. Ground that stays damp or unusually green, a smell outside, paving that has started to move. If everything drains normally but something outside is not right, a leak is the more likely explanation.
Can a drain leak without ever backing up?
Yes, and that is exactly what makes them expensive to ignore.
Waste water escaping through a crack or failed joint disappears into the sand and never backs up. The drain keeps working, so nothing prompts you to call anyone, while the ground around the pipe is being washed out year after year.
What does a camera inspection involve?
We feed a camera through the line from an access point and record what is there.
It shows the condition of the pipe, where any crack, root intrusion or collapse sits, and how far along the line it is. From that we know what the repair involves before anything is dug up.
Do you have to dig to find the fault?
Only where the fault is in a buried section that cannot be repaired from inside the line.
Locating equipment pinpoints the position first, so if excavation is needed it is one targeted hole rather than a trench following the pipe. Many faults are dealt with without digging at all.
Why does my drain keep blocking after being cleared?
Because clearing removes what is caught, not what is catching it.
If roots have entered a joint, or a section has cracked or lost its fall, the line will keep collecting waste at that point no matter how many times it is cleared. That is why we camera it rather than clearing it and leaving.
Can tree roots really break a pipe?
Yes, and they are the single most common cause of drain failure in established Perth suburbs.
Roots find moisture. A hairline gap at a joint is enough to get in, and once inside the root thickens season after season until the pipe is forced apart. What starts as a slow drain ends as a broken line.
Will I know the price before you start?
Yes. We assess the drain onsite, camera the line where needed, and quote before repair work begins.
Our quotes are final wherever they can be, and we do not upsell work your home does not need.
Do you clear the blockage on the same visit?
In most cases, yes. We carry locating, camera and high pressure jetting equipment, so clearing and diagnosis happen in the one visit.
Where the camera shows a structural fault, we will explain what the repair involves and quote it separately rather than clearing it and saying nothing.
Which areas of Perth do you cover?
We cover Perth’s northern suburbs, from Two Rocks in the north down to Scarborough, and inland to Landsdale.
Call 0400 838 622 and we will confirm we can get to you.
Can a leaking drain damage my house?
It can. Water escaping into sandy soil washes fines away from around the pipe and from under whatever sits above it.
Over time that shows up as sinking paving, a moving path, or in more serious cases movement affecting slabs and footings. The pipe repair is rarely the expensive part; what the water has been doing to the ground is.
Do drain chemicals from the supermarket work?
Rarely on anything structural. They may shift a soft build-up of grease or soap in a basin, but they do nothing to roots, a crack, or a collapsed section.
They also make the job more hazardous for whoever opens the line afterwards, and repeated use can attack older pipework. If a drain has blocked more than once, it needs looking at, not more chemical.
What is high pressure jetting?
Water delivered through the line at high pressure to cut through build-up, grease and root matter, and flush the debris away.
It cleans the full bore of the pipe rather than punching a hole through the middle of a blockage, which is why the drain stays clear longer afterwards.
Can a cracked drain be repaired without replacing the whole line?
Often, yes. If the rest of the line is sound, a single cracked or root damaged section can be dealt with on its own.
Where the camera shows the whole run is at the end of its life, replacing a metre simply moves the problem. We will tell you plainly which situation you are in.
How old are the drains in most Perth homes?
It depends on the age of the house. Older established suburbs often still have clay or earthenware drainage, which is brittle and joins in short sections, making it vulnerable to roots and movement.
Newer homes use PVC, which is far more resilient, though poor fall and construction debris are more common in those.
Can I see what the camera sees?
Yes. You are welcome to watch the screen while we run the camera through.
It is far easier to make a decision about a repair when you have seen the fault yourself rather than being told about it.
Do you attend rental properties?
Yes. We attend rental and strata properties across Perth’s northern suburbs.
Call 0400 838 622 and we will let you know what we can do and how approvals are best handled for your situation.
Should I get the drains checked before buying a house?
It is worth considering, particularly on an older property with established trees.
Drainage is not visible during a normal inspection and a fault in a buried line is one of the more expensive things to inherit. A camera run through the main line answers it in under an hour.
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.
