How to Clear a Blocked Drain: 7 Effective DIY Tips

Dealing with a blocked drain can be a frustrating and messy experience. A block should not disrupt your daily routine and lead to unpleasant odours and potential water damage, whether a slow-draining sink, a backed-up shower, or a clogged toilet. Fortunately, learning how to clear a blocked drain doesn't have to be complicated or expensive.

In this post, we'll share seven effective DIY tips to help you swiftly unblock your drain and restore your plumbing to normal.

Identify the Cause of the Blockage

Before diving into the methods of unblocking a drain, it's essential to identify the cause of the blockage. Common culprits include hair, grease, soap scum, and foreign objects that have accidentally found their way down the drain.

Tip: To inspect the drain, you can use a flashlight to look into the pipe. For sinks and showers, removing the drain cover can give you a better view. Sometimes, the cause is visible, and you can remove it with your hands or tweezers. If the blockage is deeper, use one of the methods outlined below.

Use Boiling Water

Boiling water is one of the simplest and most effective methods for clearing minor blockages. This method is particularly useful for blockages caused by soap scum, grease, or small particles.

Step-by-Step Guide:

Boil a kettle of water.
Carefully pour the boiling water directly into the drain in two to three stages, allowing the water to work for a few seconds between each pour.
If the water stands in the sink without draining, wait a few minutes and try again.

Note: This method is unsuitable for PVC pipes, as high temperatures can cause damage. Additionally, avoid using boiling water if your sink is connected to a garbage disposal, as the extreme heat can harm the disposal's components.

Plunge the Drain

A plunger is a handy tool that can be used to clear blockages in sinks, toilets, and showers. It works by creating a vacuum that helps to dislodge the obstruction.

Step-by-Step Guide:

Fill the sink or tub with enough water to cover the plunger's cup.
Place the plunger over the drain, ensuring it covers the opening completely.
Push down firmly and then pull up sharply, repeating this motion several times.
After a few plunges, lift the plunger to see if the water drains away.
If the blockage is still present, repeat the process several times.

Tip: For toilets, use a flange plunger designed explicitly for this purpose. Ensure there's enough water in the bowl to cover the plunger and use the same plunging technique.

Baking Soda and Vinegar Solution

Combining baking soda and vinegar creates a chemical reaction that can help break down blockages. This method is environmentally friendly and safe for most types of pipes.

Step-by-Step Guide:

Pour boiling water into the drain.
Add half a cup of baking soda and let it sit for several minutes.
Combine one cup of vinegar with hot water and pour it down the drain.
Cover the drain with a plug or cloth to keep the reaction contained.
After 10-15 minutes, flush the drain with boiling water again.

Use a Drain Snake or Auger

A drain snake or auger can be very effective for more stubborn blockages. These tools can reach deep into the drain and retrieve the obstruction.

Step-by-Step Guide:

Insert it into the drain until there's resistance.
Rotate the handle to hook onto or break up the blockage.
Gently pull the snake back out, bringing the debris with it.
Run water down the drain to see if it's clear. Repeat if necessary.

Tip: For toilets, use a toilet auger, which is specifically designed to navigate the bends in the plumbing.

Wet and Dry Vacuum

If you have such a vacuum, you can use it to suck out the blockage. This method is particularly useful for large or hard-to-reach obstructions.

Step-by-Step Guide:

Set the vacuum to liquids if it has a setting for this.
Create a seal over the drain with the vacuum hose. You can use an old plunger head or a cloth to help seal the seal.
Turn on the vacuum to the highest setting to suck out the blockage.

Tip: Be careful when using this method, as a strong vacuum can cause damage if not used correctly. Ensure all settings are appropriate for liquid and the suction power is not excessive.

Chemical Drain Cleaners

Chemical drain cleaners are a last resort due to their harsh nature and potential to damage pipes. However, they can be effective for particularly stubborn blockages.

Step-by-Step Guide:

Adhere to the guidelines provided on the chemical cleaner's label.
Use gloves and eye protection to prevent contact with the chemicals.
Pour the suggested cleaner into the drain and let it sit for the recommended time.
Rinse the drain thoroughly with ample water.

Note: Use chemical cleaners sparingly and only as a last resort, as they can harm your plumbing and the environment.

Prevention Tips

Preventing blockages is easier than dealing with them. Here are some simple tips to keep your drains clear:

Regularly pour boiling water down the drain to prevent grease buildup.
Drain covers are used to catch hair and food particles.
Avoid pouring grease, coffee grounds, and large food particles down the sink.
Periodically use a baking soda and vinegar solution to maintain clear pipes.
