What causes blocked drains in Canning Vale homes

Blocked drains can happen to any home but the reasons aren't always what you'd expect. Kitchen grease and bathroom hair are common culprits sure, though Canning Vale has some local factors that make drain blockages a bit different here compared to other parts of Perth.

Sandy soils from the Canning basin sit under a lot of Canning Vale properties, and you'll find garden reticulation systems running across most of the housing estates. What happens over time is sand, silt, and those fine mineral deposits wash down through outdoor gullies and into stormwater lines, building up inside the pipes and restricting flow in a way you probably won't notice until things get really bad. It's a genuinely common local cause — not just your kitchen grease.

Other things that block drains around here include:

• Fats, oils, and grease — poured down the kitchen sink, they solidify in the pipe and trap other debris.
• Hair and soap scum — bathroom drains are notorious for this combination slowly strangling flow.
• Wet wipes, nappies, and sanitary products — even "flushable" wipes don't break down and cause major blockages.
• Tree roots — roots seek moisture and infiltrate pipes, especially older ones (more on this below).
• Foreign objects — toys, cotton buds, and other items accidentally flushed or washed down.
• Sand, silt, and mineral build-up — a genuine Canning Vale and south Perth issue linked to local soils and reticulation.

You start noticing a sink that's draining slow or a toilet that gurgles — worth getting it checked early before it turns into something worse. You can read more in our guide to the signs of a blocked drain.

Tree roots and clay pipes in the older streets nearby

Tree roots are one of the most stubborn causes of a blocked drain, and they're especially relevant to the suburbs surrounding Canning Vale that we service every day. Here's why.

Canning Vale itself was largely market gardens, dairy farms, and swampy, high-water-table land until the late 1970s. It filled with housing estates mainly through the late 1990s and 2000s — five primary schools opened between 1994 and 2007 alone. That means most Canning Vale homes were plumbed with modern PVC sewer pipe from day one, which doesn't have joints that roots can penetrate easily.

However, the picture is very different in the older streets we also service — particularly the 1950s–80s parts of Thornlie, and older Gosnells and Riverton homes. Many of those properties still have vitrified clay pipe in the ground. Clay pipes have joints every metre or so, and over decades those joints crack, shift, and open up just enough for tree roots to sneak in. Once inside, roots thrive in the moisture and nutrients of the sewer line, growing into dense blockages that a simple machine clear often can't fully solve.

If you suspect tree roots are causing your blocked drain — especially if you live in an older part of Thornlie, Riverton, or Gosnells — we'll confirm it with a CCTV drain camera and then clear them properly with hydro-jetting. Learn more in our article on tree roots in drains.

Warning signs of a blocked drain

A blocked drain rarely happens without warning. If you catch the signs early, you can usually avoid a bigger (and more expensive) problem. Keep an eye out for:

• Slow-draining sinks, showers, or bathtubs — water taking longer than usual to drain away.
• Gurgling toilet or drains — air trapped in the pipes by the blockage causing bubbling sounds.
• Bad sewage smell — a persistent odour from drains or in the yard.
• Water pooling around outdoor drains — especially after heavy rain or reticulation runs.
• Toilet water level rising unusually high when flushed.
• Multiple fixtures blocked at once — if the toilet, shower, and sink are all slow, that often points to a main sewer line blockage.

You're seeing any of these signs, don't leave it. Check our full guide on the signs of a blocked drain or call us to get it sorted.

How much does it cost to clear a blocked drain in Canning Vale?

Cost is one of the first questions we get asked, so here are some honest numbers for you.

Here's a rough guide to what Canning Vale homeowners pay:

What drives the price? The depth and severity of the blockage, the pipe material, whether tree roots are involved, and how accessible the affected section is. We'll always confirm a fixed price on site after the CCTV inspection — no surprises, no hidden extras. You'll know the exact cost before we start any work.

How we clear blocked drains

We don't believe in guessing. Every blocked drain call-out follows a clear process to find the problem, clear it properly, and show you what we found.

CCTV drain inspection

We start by feeding a high-definition CCTV drain camera into your pipe. This gives us a real-time view of what's happening inside — whether it's tree roots, a build-up of grease and sand, a collapsed section, or something else entirely. You'll see the footage yourself on our monitor, and we'll explain exactly what we're dealing with. This step is what separates a proper diagnosis from a plumber who just snakes the line and hopes for the best. Read more about how it works in our guide to CCTV drain inspection and hydro-jetting.

Hydro-jetting

Once we know what the blockage is, we clear it using high-pressure hydro-jetting. A specialised nozzle delivers water at pressures up to 5,000 PSI, blasting through grease, sand, silt, soap build-up, and even cutting through stubborn tree roots. Unlike a basic drain snake that just punches a hole through the blockage, hydro-jetting scours the full diameter of the pipe clean, which means the drain stays clear longer. It's the most effective method for both Canning Vale's sandy-soil sediment issues and the root-choked older pipes in nearby suburbs.

Wondering why we favour jetting over a basic drain machine? Here's how the two stack up:

Repairs and relining

If our CCTV inspection reveals a cracked, collapsed, or badly root-damaged section of pipe, we'll talk you through your repair options. For many jobs, pipe relining is the smart choice — it creates a new pipe-within-a-pipe without the need to dig up your garden or driveway. For more serious damage, excavation and pipe replacement may be necessary. Either way, we provide upfront pricing before any work starts so you can make an informed decision.

Preventing blocked drains

You can't prevent every blocked drain, but a few simple habits go a long way:

• Never pour fats, oils, or grease down the sink — wipe pans with paper towel first and bin it.
• Use drain strainers in showers and sinks to catch hair and food scraps.
• Only flush toilet paper — wet wipes, cotton buds, and sanitary products go in the bin.
• Have your drains inspected every couple of years, especially if you're in an older home with clay pipes.
• Keep an eye on outdoor gullies after heavy rain or reticulation — sand build-up is a real issue locally.

When to call a plumber

A minor slow drain can sometimes be cleared with a plunger or a dose of enzyme-based drain cleaner from the hardware store, and that's fine for a first attempt. But if the blockage keeps coming back, if you're dealing with a blocked toilet that's overflowing, or if wastewater is backing up into your home — that's an emergency, and you need a licensed plumber now.

In Western Australia, drainage work must be carried out by a licensed plumber. All Canning Vale homes connect to the Water Corporation sewer network, and any work on sewer lines needs to be done to standard by someone who's licensed and insured. Doing it yourself or using an unlicensed operator risks damaging the network and can land you in trouble with local regulations.
