How to Unblock Drains: Essential Maintenance Steps for Every Homeowner

A functional drainage system is an essential part of a comfortable home. We often take it for granted until the moment it stops working as it should. Blocked drains aren't only annoying; they can actually lead to significant structural issues and health hazards if left unaddressed.

At All Plumb Melbourne, we’ve seen firsthand how quickly a small clog can escalate into a plumbing emergency. It could be a slow-draining kitchen sink or a complete blockage in your main sewer line, but either way, knowing the right steps to take will save you a lot of time and money.

Understanding Blocked Drains

Your home is fitted with a complex network of pipes designed to carry wastewater away from your fixtures and into the local sewer system. A blockage happens when an obstruction prevents water flow through these pipes, whether completely or only partially.

Drain blockages can occur anywhere from the small P-trap under your bathroom sink to the deep underground pipes that connect your property to the street. While some clogs are close to the surface and easy to reach, others are deep within the drainage system and require professional tools to locate and clear.

Common Causes of Blocked Drains

Figuring out why your pipes are clogging is the first step toward a permanent solution. We've outlined a few of the main culprits responsible for the majority of residential plumbing issues:

Tree Roots

Tree root intrusion is a less-often considered but frequent cause of severe blockages. Trees have a natural instinct to seek out moisture, and the condensation or small leaks found in older clay pipes are irresistible to them. Once tree roots find a way into a pipe, they grow rapidly, creating a net that catches other debris.

Food Particles and Kitchen Grease

A lot of people don't think much about what goes down their kitchen sinks. After all, if it can fit down the drain, there shouldn't be any issues, right? But even though fats, oils, and grease might enter the sink as liquids, as they cool, they solidify on the interior walls of the pipes. Over time, these layers thicken and trap food particles, eventually closing off the pipe entirely.

Hair and Soap Scum

In bathrooms, the combination of shed hair and soap scum creates a thick, sticky substance that is notoriously difficult to move. This mixture clings to the sides of the pipe and acts like a magnet for more hair, leading to a stubborn clogged drain.

Foreign Objects

Items that should never be flushed, such as "flushable" wipes, sanitary products, and even small children's toys (we see this quite often!) are common causes of sudden blockages in the main sewer line.

If you are dealing with stubborn blocked drains in Reservoir or Moonee Ponds, All Plumb Melbourne's team can provide quick and affordable solutions.

Signs You Have a Blocked Drain

Recognising the early warning signs of a clog allows you to take action before you are faced with an overflowing toilet or a flooded laundry.

1. Gurgling Noises: If you hear strange glugging or gurgling noises coming from your drains when you run water elsewhere in the house, it suggests that air is being trapped by an obstruction and being released gradually, causing that tell-tale sound.
2. Slow Drainage: This is usually the first sign. If water takes longer than usual to flow down the plug hole, a clog is likely forming which is partially obstructing the pipe.
3. Foul Odours: Rotting food or stagnant water trapped behind a blockage will eventually start to produce odours. If your sink or toilet is making your eyes water, even after a deep clean, it's likely that the smell is coming from deeper in the plumbing.
4. Changes in Water Level: If the water in your toilet bowl sits unusually high or low, there is likely an issue in the pipes or the sewer line. However, this could also be an issue with the mechanism in your cistern (the tank on the back of the toilet), which should also be addressed by a plumber.

Preventing Blocked Drains

Prevention is always more cost-effective than repair. By putting a few simple maintenance practices into place, you can keep your plumbing system running smoothly for years.

Routine Maintenance

Flush your household drains with boiling water once a week. This helps to melt away any grease or soap scum before it has a chance to harden. For a more thorough clean, an enzyme-based mixture can be used periodically to break down organic matter without harsh chemicals, which can cause issues with older or damaged pipes.

Proper Waste Disposal

Be mindful of what goes down your sinks. Use drain screens in the kitchen to catch food particles and in the shower to collect hair. Never pour cooking oil down the drain, instead, collect it in a jar and dispose of it in the bin once cooled.

DIY Solutions to Blocked Drains

When a clog happens, you may be tempted to reach for DIY methods before calling in the professionals. While some of these are effective for minor issues, they should be used with caution. Here are a few first steps to try:

Baking Soda and Vinegar

This is a popular natural hack for cleaning blocked drains. Start by pouring a pot of boiling water down the drain. Follow this with half a cup of baking soda and let it sit for a few minutes. Then, pour a mixture of one cup vinegar and one cup hot water over the baking soda. Cover the drain with a plug to keep the reaction inside the pipe. After ten minutes, flush it again with boiling water. Mixing baking soda and vinegar causes a bubbling chemical reaction, which can help break up minor clogs.

Using a Plumber's Snake

For clogs that are a bit further down, a drain snake or manual auger can be used. By inserting the cable into the pipe and cranking the handle, you can physically break apart the blockage or hook onto the debris to pull it out. Be careful not to force the snake, as you could damage the pipe walls.

The Traditional Plunger

A plunger is often the most effective tool for a kitchen sink clog. Ensure you have a tight seal around the drain and use firm, rhythmic pressure to create suction that dislodges the obstruction.

Maintaining Your Sewer Line

Many homeowners forget that their responsibility extends to the main sewer line that runs under their property. Routine checks of this line are essential, especially if you have large trees on your land. Periodic professional drain cleaning can clear out small clogs or tree roots before they cause a burst pipe, preventing expensive water damage and emergency repair costs.

When DIY Isn't Enough: Professional Drain Cleaning

Sometimes, DIY solutions simply won't cut it. If you find that your drains are constantly clogging or if multiple fixtures in your home are backed up at once, the problem is likely deep within your drainage system or the main sewer line.

Professional plumbers use advanced CCTV technology to perform video inspections of your pipes. This allows us to see exactly what is causing the blockage, whether it is a tree root, a collapsed pipe, or a build-up debris. Once the cause is found, we use high-pressure water jetting or industrial drain snakes to clear the line completely.

Professional cleaning services are more thorough than DIY methods because they remove the entire obstruction rather than just punching a small hole through it. This reduces the likelihood of the clog returning a few weeks later.

The Risks of Chemical Drain Cleaners

While it is tempting to buy a bottle of liquid drain cleaner from the supermarket, these products can often cause more harm than good. Most store-bought cleaners use caustic chemicals that generate heat to dissolve clogs. This heat can soften PVC pipes or damage the older metal pipes found in many Melbourne homes. If the cleaner fails to clear the blockage, you may be left with a sink full of toxic chemicals that makes it more dangerous for a plumber to work on later.
