The Different Methods of Unblocking Toilets by Experts

Unblocking a toilet can run from simple to complex, depending on the severity of the blockage. Professional plumbers utilise several methods to clear toilet blockages, and understanding these methods can help homeowners decide when to call an expert and what to expect. Here are the different methods professionals use to Unblocking toilets:

Plunger Method

How It Works:

A plunger is a common tool for unblocking toilets. It creates a vacuum and uses pressure to dislodge the blockage. Plumbers prefer a flange plunger for toilets, which has an additional soft rubber flap that fits snugly into the toilet drain.


Position the flange plunger over the toilet drain, ensuring a tight seal.

Pump the plunger up and down forcefully to generate sucking and pressure.

Continue this action until the water starts to drain, indicating the blockage has been dislodged.


This method is effective for minor blockages caused by organic waste or toilet paper.

Plumbing Snake or Auger

How It Works:

A plumbing snake, or an auger, is a flexible, coiled metal wire that can reach deeper into the toilet’s plumbing system. It is designed to break up or retrieve the obstruction.


Insert the drill into the toilet drain until resistance is felt.

Rotate the handle to drive the drill deeper into the clog.

Either break up the blockage or pull it out, then retract the auger.


It is highly effective for blockages that are too deep or stubborn for a plunger. It can handle more solid obstructions, like small toys or thick wads of toilet paper.

Chemical Drain Cleaners

How It Works:

Chemical drain cleaners use strong chemicals to dissolve organic matter causing the blockage. These cleaners contain caustic substances like sodium hydroxide or sulfuric acid.


Pour the recommended amount of cleaner into the toilet.

Allow it to sit for the specified time to dissolve the clog.

Flush the toilet to crisscross if the obstruction is clean.


It is effective for organic blockages but should be used cautiously due to potential damage to pipes and safety hazards.

Hot Water and Dish Soap

How It Works:

This method uses hot water and dish soap to break down the blockage by lubricating the clog and pipes, making it easier to flush away.


Spray a large amount of dish soap into the toilet.

Pour a bucket of hot (not boiling) water into the bowl.

Let it sit for about 15-20 minutes.

Attempt to flush the toilet.


Works well for minor, greasy blockages. It’s a safe, non-toxic method that is gentle on plumbing systems.

High-Pressure Water Jetting

How It Works:

High-pressure water jetting uses a specialised hose and nozzle to blast water at high pressures through the plumbing system, breaking up and washing away the blockage.


Insert the jetting nozzle into the toilet drain.

Activate the jetting system to send a powerful stream of water through the pipes.

Move the nozzle through the pipes to ensure thorough cleaning.


This method is extremely effective for severe or recurring blockages, including those caused by mineral buildup, grease, and heavy organic matter. Due to the equipment and skill required, it is usually employed by professionals.

Unblocking toilets

Vacuum Method

How It Works:

A wet/dry vacuum can be used to either suck out or blow out the blockage.


Set the vacuum to wet mode.

Create a seal with the vacuum hose on the toilet drain.

Use the vacuum to either draw the blockage out or push it through the plumbing.


Effective for blockages close to the drain entrance and for solid items that can be dislodged or sucked out.

Manual Removal

How It Works:

In some cases, the blockage might need to be manually removed. This involves dismantling the toilet or using specialised tools to extract the obstruction.


Shut off the water supply to the toilet.

Drain the toilet bowl and tank.

Remove the toilet if necessary to access the blockage.

Manually extract the blockage using gloved hands or tools.


This method is highly effective for solid objects that cannot be broken up or dissolved. However, it requires professional expertise to avoid damaging the toilet or plumbing.
