How to Clear a Blocked Drain

Expert Advice from Newcastle Plumbing Services: How to Clear a Blocked Drain

A blocked drain isn’t just inconvenient—it can be downright disruptive. Whether it’s a slow-draining sink, a foul-smelling bathroom, or water pooling where it shouldn’t, drain blockages have a way of demanding attention at the most inopportune times. Fortunately, you don’t always have to call in the pros right away. With the right techniques, tools, and advice, you can often solve the problem yourself—or at least understand what’s going on before you pick up the phone.

We spoke with the seasoned team at Newcastle Plumbing Services, a trusted name in the Hunter region for over two decades, to get expert tips on how to identify, approach, and clear a blocked drain.

Here’s what they had to say.

Understanding the Causes of Blocked Drains

Before you can clear a blocked drain, it helps to know what might be causing the problem. According to the team at Newcastle Plumbing Services, the most common culprits include:

• Hair buildup in bathroom drains
• Grease and fat solidifying in kitchen sinks
• Foreign objects like baby wipes, sanitary items, and paper towels
• Tree roots invading outdoor pipes
• Soap scum and mineral buildup over time

Identifying the likely cause based on the location of the blockage can help you choose the most effective solution. For example, hair and soap residue are common in shower drains, while fat and food scraps are kitchen sink offenders.

Step 1: Spot the Signs of a Blocked Drain

Often, the signs are obvious—but sometimes they creep up on you. Be on the lookout for:

• Water draining slowly
• Gurgling noises from the pipes
• Foul smells coming from the drain
• Rising toilet water levels
• Overflowing outdoor drains

The earlier you catch a blockage, the easier it is to deal with. Newcastle Plumbing Services recommends acting quickly as soon as you notice a problem, to avoid further damage or expensive repairs.

Step 2: Try a DIY Fix First

If you’re confident the blockage isn’t too severe, and you’re comfortable getting your hands a little dirty, there are several methods you can try before calling a plumber.

1. Boiling Water (for Minor Kitchen Blockages)

For grease or soap-related blockages, sometimes a simple flush with boiling water is enough.

How to do it:

• Boil a full kettle of water
• Pour it slowly down the affected drain in stages, allowing it to work between pours

This method is particularly effective in kitchen sinks, where fats and oils tend to congeal.

2. Baking Soda and Vinegar

This classic combo is a natural alternative to chemical drain cleaners and is safe for most plumbing.

How to do it:

• Pour ½ cup of baking soda into the drain
• Follow with 1 cup of vinegar
• Let it fizz and bubble for 10–15 minutes
• Rinse with hot water

It’s not magic, but it can break down organic matter and clear mild clogs.

3. The Plunger

An old-school favourite, the plunger is still one of the most effective tools for clearing blocked sinks, showers, and toilets.

How to do it:

• Ensure there’s enough water in the basin to cover the plunger head
• Create a tight seal and pump vigorously up and down for 20–30 seconds
• Release to see if water drains; repeat as necessary

Pro tip from Newcastle Plumbing: For double sinks, block the second drain to maintain pressure.

4. Drain Snake (Electric Eel)

For tougher clogs, a manual or motorized drain snake can physically break through the blockage.

How to do it:

• Feed the snake into the drain until you hit resistance
• Turn the handle to dislodge or hook the blockage
• Pull it out slowly, then flush the drain with hot water

This tool is especially handy for bathroom sink and shower drains where hair clogs are common.

Step 3: Know When to Call in the Experts

While DIY can solve a lot, sometimes the problem goes deeper—literally.

When to call Newcastle Plumbing Services Blocked Drain Specialist:

• DIY methods haven’t worked
• The blockage is recurring
• You suspect tree roots or structural pipe damage
• Water is backing up into multiple fixtures
• There’s a strong sewage smell inside your home

Professional plumbers use advanced diagnostic tools like CCTV drain cameras and hydro jetting to identify and clear stubborn blockages efficiently and safely.

Professional Solutions for Stubborn Drains

Newcastle Plumbing Services uses a combination of modern technology and decades of expertise to solve even the nastiest of drain issues. Here’s a quick look at their go-to methods:

1. CCTV Drain Inspection

This involves feeding a small waterproof camera into the pipes to visually inspect the blockage, identify cracks, root intrusion, or collapsed pipes

2. High-Pressure Water Jetting

A hydro jet uses high-pressure water streams to obliterate blockages and clean the inside walls of pipes, restoring full flow. It’s particularly effective for grease build-up and tree roots.

3. Electric Eel (Drain Snake Machine)

A powerful, rotating steel cable cuts through clogs and clears the path. This is used when a blockage is too dense for hydro jetting.

4. Pipe Repair

If the blockage was caused by pipe damage, Newcastle Plumbing Services can offer to repair the issue.

Prevention Tips from the Pros

“An ounce of prevention is worth a pound of cure,” says one of the senior plumbers at Newcastle Plumbing Services. To avoid future headaches, follow these simple tips:

• Never pour fats or oils down the kitchen sink
• Use drain covers to catch hair and debris in showers and sinks
• Flush only toilet paper—no wipes, even if they say ‘flushable’
• Run hot water down the sink after doing dishes
• Have your drains professionally inspected every few years if you live in an older home

These small habits can significantly reduce the risk of future blockages.
