Blocked Drain Repair & Drain Cleaning in Canning Vale

A slow-draining sink or a gurgling toilet is easy to ignore until wastewater is backing up over your floor. Blocked drains are one of the most common jobs we see across Canning Vale, Thornlie, Willetton and the wider Perth south-east, and they almost never sort themselves out. The good news is that a properly diagnosed blockage is usually straightforward to clear, and there's plenty you can do to stop it coming back.

This guide walks through what causes blocked drains, the early warning signs, and how we clear them using CCTV cameras and high-pressure hydro-jetting rather than guesswork.

What causes blocked drains in Perth homes

Most blockages come down to a handful of everyday culprits. Knowing which one you're dealing with helps us clear it properly the first time.

Fats, oils and grease poured down the kitchen sink cool and harden inside the pipe, catching food scraps until the pipe closes over.
Hair and soap in bathroom and laundry drains bind together into stubborn clumps.
Wet wipes, nappies and sanitary products that don't break down like toilet paper does.
Tree roots creeping into cracked or joined sewer pipes, a big issue in Perth's older suburbs.
Foreign objects such as kids' toys, cotton buds and dental floss.
Sand, soil and mineral build-up, common where reticulation and garden runoff finds its way into drains.

Tree roots and clay pipes

Many established homes around Gosnells, Riverton and the older parts of Thornlie were plumbed with vitrified clay sewer pipes. Over decades these develop tiny cracks and their joints loosen, and thirsty tree roots follow the moisture straight in. Once inside, roots keep growing and trap everything that flows past. If you've got mature gum trees or a leafy verge, roots are a likely cause. We cover this in more depth in our guide on tree roots in drains.

Warning signs of a blocked drain

Catching a blockage early saves you money and mess. Keep an eye out for these signs, and read our full rundown of the signs of a blocked drain if you want to dig deeper.

Water draining slower than usual in sinks, showers or the bath
Gurgling sounds from drains or the toilet
A bad smell drifting up from the drain or gully
Water pooling around floor wastes or in the shower
The toilet level rising when you flush, or dropping oddly
More than one fixture playing up at once, which usually points to a blockage deeper in the main sewer line

How we clear blocked drains

Pouring supermarket drain cleaner down the pipe might shift a minor clog, but it won't touch tree roots or a collapsed pipe, and the harsh chemicals can damage older pipework. We use professional methods that actually find and fix the problem.

CCTV drain inspection

We feed a waterproof camera down the drain to see exactly what's going on, in real time. That tells us where the blockage sits, what's causing it, and whether the pipe itself is cracked, sagging or root-invaded. No digging up the garden to guess. It also means we can show you the issue on screen rather than asking you to take our word for it. Learn more about our CCTV drain inspection and hydro-jetting service.

Hydro-jetting

Once we know what we're dealing with, high-pressure water jetting is usually the most thorough way to clear it. A specialised nozzle blasts water through the pipe to cut through grease, sludge and tree roots, scouring the pipe walls back to a near-original bore. It's far more effective than a traditional cable machine for build-up and roots, and because it uses water rather than chemicals it's safe for most pipework.

Repairs and relining

If the camera shows a cracked or collapsed pipe, clearing the blockage is only half the job. We'll talk you through the repair options, whether that's a spot repair, pipe relining or, in worst cases, replacing a section. You'll get clear, upfront pricing before any work starts, so there are no surprises.

Preventing blocked drains

A few simple habits go a long way toward keeping your drains flowing.

Never pour fats, oils or cooking grease down the sink. Let them cool and bin them.
Use a drain strainer in the kitchen sink and shower to catch scraps and hair.
Only flush the three Ps: pee, poo and paper. Wipes labelled "flushable" are anything but.
Run hot water through the kitchen sink after washing up to keep grease moving.
If you've got trees near your sewer line, book a periodic CCTV check to catch root intrusion before it becomes a full blockage.

When to call a plumber

A single slow sink might be a job you can tackle with a plunger. But if the water's backing up, more than one fixture is affected, you can smell sewage, or the same drain keeps blocking, it's time to call in a licensed plumber. Recurring blockages almost always mean there's an underlying problem, like roots or a damaged pipe, that a plunger will never fix.

In Western Australia, drainage work should be carried out by a licensed plumber, and for good reason. Getting it right protects your home, your health and the Water Corporation sewer network your property connects to. If wastewater is overflowing right now, that's an emergency, and our 24/7 emergency plumbers can help.

Blocked drains only get worse and more expensive the longer they're left. If yours is playing up, call our licensed Canning Vale plumbers or request a quote today. We'll diagnose the real cause with CCTV, clear it properly, and give you honest, upfront pricing before we start, so you know exactly where you stand.

Frequently asked questions

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

It depends on the cause and how deep the blockage sits. A minor clog is far cheaper than clearing tree roots or repairing a collapsed pipe. That's why we inspect first with a CCTV camera, then give you a clear, upfront price before any work begins, so there are no surprises on the invoice.

Can I clear a blocked drain myself?

A plunger or drain snake may shift a minor sink or shower clog. But avoid harsh chemical drain cleaners, as they can damage older pipes and won't touch tree roots or grease build-up. If the blockage keeps returning or affects more than one fixture, call a licensed plumber to find the real cause.

What is hydro-jetting?

Hydro-jetting uses a high-pressure water nozzle fed into the drain to blast away grease, sludge and tree roots, scouring the pipe walls clean. It's far more thorough than a traditional cable machine and uses only water, so it's safe for most pipework and leaves your drains flowing like new.

Why does my drain keep blocking?

A drain that blocks over and over usually has an underlying problem, most often tree roots in a cracked sewer pipe, a sag in the line, or ongoing grease build-up. A CCTV inspection shows exactly what's going on so we can fix the cause, not just the symptom, and stop it recurring.
