A blocked laundry drain causes slow draining, water backing up, and a washing machine that will not drain properly, since they share the same waste pipe. Our licensed plumbers clear the trap and waste, and use a drain machine or high-pressure jetter for deeper blockages, scouring the pipe clean and finding the cause so it does not keep returning. We get your laundry and washing machine draining freely again, with an upfront fixed price. We clear blocked laundry drains across Brisbane, Perth and Adelaide, with same-day service where we can.

What causes a blocked laundry drain

Laundry drains block for a predictable set of reasons, building up over time:

Lint from washing, which accumulates in the drain and trap
Hair and fibres washed out of clothes
Detergent and fabric softener residue, which can build up and bind debris
Small items from pockets, coins, tissues, socks
Dirt, sand and grit from heavily soiled clothes
Mineral and scale build-up from hard water

Lint is the biggest culprit, because the large volume of water a washing machine discharges carries a lot of it into the drain, where it mats together with hair and residue and slowly chokes the pipe.

Signs of a blocked laundry

A blocked laundry drain shows itself in a few ways: the laundry tub draining slowly, water backing up out of the tub or the standpipe when the washing machine drains, the floor flooding when the machine empties, gurgling sounds, and bad or musty smells from the drain. Often the first sign is the washing machine, which discharges a large volume of water quickly and so reveals a partly blocked drain that cannot cope with the flow. If water backs up or floods when your machine drains, the laundry drain is blocked or restricted and needs clearing before it causes water damage.

The washing machine connection

Your washing machine usually drains into the laundry tub or a dedicated standpipe, which connects to the same waste as the tub, so a blocked laundry drain directly affects the machine. When the drain is partly blocked, it cannot handle the fast, high-volume discharge from the machine, so water backs up out of the tub or standpipe, or floods the floor, even though the tub might drain slowly but adequately on its own. This is why a blocked laundry drain so often shows up as a washing machine problem. Clearing the shared drain resolves both, and we check the connection and standpipe are correct too.

Why lint is the main culprit

Lint is to laundry drains what hair is to bathroom drains, the main cause of blockages. Every wash sheds fibres and lint from clothes and towels, and the large volume of water the machine discharges carries it into the drain. There, the lint mats together with hair, detergent residue and grit, coating the pipe and the trap and slowly narrowing the drain until it blocks. Because you cannot see it happening, a laundry drain can seem fine for a long time and then suddenly back up. Fitting a lint trap on the washing machine outlet hose catches much of this lint before it reaches the drain, preventing most blockages.

What you can try first

For a mild laundry blockage, a few things are worth trying before you call:

Clear the tub waste and plug of visible lint, hair and gunk
Check and clean the trap under the tub if accessible
Pour a kettle of hot (not boiling) water down to soften residue
Plunge the tub waste firmly with a cup plunger

Avoid harsh chemical drain cleaners, which can damage pipes and seals and are hazardous. If the water still backs up when the machine drains, or the tub will not clear, the blockage is deeper in the line and needs a plumber with the right equipment.

How we clear a blocked laundry drain

We clear the blockage properly and find out why it happened. Depending on the job we clear the tub waste and trap, and for deeper blockages use a drain machine (electric eel) to break up and pull out the lint and debris clog, or a high-pressure water jetter to scour the pipe walls clean. If the laundry keeps blocking, a drain camera can inspect the pipe to confirm the cause. Jetting is particularly effective because it washes the matted lint and residue right off the pipe walls rather than just punching through, so the drain is genuinely clear and less likely to re-block quickly.

When the machine floods the floor

A common and alarming symptom of a blocked laundry drain is the floor flooding when the washing machine empties. This happens because the drain cannot cope with the fast, high-volume discharge from the machine, so the water backs up out of the tub or standpipe and overflows. It is not usually the machine at fault, but the drain being partly blocked and unable to take the flow. Clearing the drain so it can handle the full discharge resolves the flooding. We clear the blockage and check the standpipe height and connection are correct, since an incorrect standpipe can also cause backups and flooding.

Recurring laundry blockages

If your laundry drain keeps blocking despite clearing the tub and trap, the cause is usually a heavy build-up of lint and residue deep in the line, or a problem in the pipe further down, such as tree roots or a damaged section. Something that clearing the visible parts will not fix. A camera inspection shows exactly what is happening, and we can jet the line clean, clear any roots, and if the pipe is damaged, repair it with no-dig pipe relining so the blockages stop returning. Recurring blockages mean an underlying cause that is worth finding and fixing, rather than clearing the same drain over and over.

Smelly laundry drains

A smelly laundry drain usually comes from lint, hair and detergent residue rotting in the waste and trap, or from a dry or faulty trap letting sewer gas through, common in a laundry used only occasionally. If your laundry smells even when it drains, the cause is often the build-up coating the pipe. Clearing and cleaning the waste and trap removes the rotting material and the smell with it, and running water refills a dry trap. We also check the trap is correctly sealed. If the smell persists after cleaning, it can indicate a venting issue, which we can investigate so your laundry stays fresh.

Blocked laundry or blocked drain?

If only your laundry is slow or backing up, the problem is usually in the tub waste, the standpipe, or the pipe nearby. If your laundry, kitchen, bathroom and other drains are all slow or backing up at the same time, the blockage is in the main drain or sewer line, which is a bigger job. Either way we can clear it. Our drain repair and camera services let us diagnose and fix the underlying cause, not just the symptom, so you are not calling us back about the same drain soon after. We will quickly establish whether it is a local laundry clog or a wider problem.

How to prevent laundry blockages

Most laundry blockages are easy to prevent. The best step is to fit a lint trap or filter on the washing machine outlet hose and clean it regularly, which catches the main cause before it reaches the drain. Empty pockets before washing so coins, tissues and small items do not go down, and clear lint and hair from the tub waste. Periodically flushing the drain with hot water helps keep residue moving. These simple habits catch the lint, debris and items that cause laundry blockages, saving you the hassle of a backed-up laundry and a flooded floor when the machine drains.

How much does it cost to clear?

Clearing a blocked laundry drain is usually an affordable job, especially when the blockage is in the tub waste, trap or nearby pipe. The cost depends on how deep the blockage is and the method needed, a trap clean is quicker and cheaper than clearing a deeper pipe blockage with an eel or jetter. Emergency and after-hours call-outs cost more than a standard appointment. We give you an upfront fixed price before we start, so you know the cost, and if there is an underlying pipe issue, we will explain the options clearly so you can choose the best fix.
