How to Fix a Blocked Drain: A Step-by-Step Guide

A blocked drain is one of those frustrating household problems that can quickly escalate if not dealt with promptly. Whether it’s in the kitchen, bathroom, or laundry, a blocked drain can cause water to back up, leading to unpleasant odours and potentially costly water damage. Fortunately, fixing a blocked drain doesn’t always require a call to the plumber. With the right techniques and a bit of elbow grease, you can often resolve the issue yourself. This guide will walk you through various methods to fix a blocked drain, using common household items and a few tools you might already have on hand.

1. Boiling Water

Method:

Start with the simplest solution—boiling water. Boil a kettle full of water and slowly pour it down the blocked drain in stages. It’s important to pour the water steadily to allow it to work through the blockage.

Effectiveness:

Boiling water is particularly effective for clearing blockages caused by grease, soap scum, and other substances that can solidify in the pipes. The heat helps to melt and dissolve these substances, allowing them to be flushed away.

Caution:

Be careful when using boiling water, especially if you have PVC pipes, as the high temperature can potentially cause damage. It’s also wise to avoid this method if your sink is connected to a garbage disposal, as the heat can harm its components.

2. Baking Soda and Vinegar

Method:

Baking soda and vinegar are a classic combination for tackling blocked drains. Here’s how to use them:

1. Pour 1/2 cup of baking soda down the drain.
2. Follow with 1 cup of vinegar.
3. Cover the drain to contain the reaction and let it sit for about 30 minutes.
4. After the fizzing stops, flush the drain with hot water.

Effectiveness:

The chemical reaction between the baking soda and vinegar creates bubbles that help to break down blockages caused by hair, soap residue, and other debris. This method is also great for neutralising odours.

3. Dish Soap and Hot Water

Method:

Pour a generous amount of liquid dish soap directly into the drain. Follow this by pouring a kettle of boiling water down the drain.

Effectiveness:

Dish soap is designed to cut through grease and grime, making it an excellent choice for kitchen sink blockages caused by food particles and grease. The hot water helps to flush the loosened debris down the drain.

4. Plunger

Method:

A plunger can be a powerful tool for clearing blockages. Here’s how to use it effectively:

1. Fill the sink or tub with enough water to cover the plunger’s cup.
2. Place the plunger over the drain, ensuring a tight seal.
3. Push down firmly and then pull up sharply, repeating this motion several times.
4. After a few plunges, lift the plunger to see if the water drains away.

Effectiveness:

Plunging is particularly effective for clearing blockages that are close to the drain’s surface. It works by creating a vacuum that helps to dislodge the blockage, allowing water to flow freely again.

5. Salt and Baking Soda

Method:

Mix 1/2 cup of salt with 1/2 cup of baking soda and pour it down the blocked drain. Let it sit for about 15 minutes, then flush with boiling water.

Effectiveness:

The abrasive nature of salt, combined with the chemical reaction of baking soda, helps to scrub away buildup inside the pipes. This method is particularly useful for tougher blockages that require a bit more effort to clear.

6. Wire Coat Hanger

Method:

Straighten out a wire coat hanger, leaving a small hook at one end. Carefully insert the hooked end into the drain and fish out any hair or debris that may be causing the blockage.

Effectiveness:

This method is especially useful for visible blockages near the drain opening, such as hair blockages in bathroom sinks or showers.

7. Yeast and Salt

Method:

Pour two packets of dry yeast down the drain, followed by 1/2 cup of salt. Then, pour a cup of boiling water down the drain and let the mixture sit for about 45 minutes before flushing with more hot water.

Effectiveness:

Yeast helps break down organic material in the drain, while salt acts as a scrubber to clear away stubborn debris. This method is effective for blockages caused by food particles or organic matter.

8. Professional Help

If you’ve tried all the above methods and your drain is still blocked, it might be time to call in a professional plumber. They have access to specialised equipment like drain snakes, high-pressure water jetters, and CCTV cameras that can identify and clear even the most stubborn blockages. Professional plumbers can also assess your plumbing system to prevent future issues.

Conclusion

Blocked drains can be a nuisance, but with the right approach, they can often be resolved quickly and easily without the need for harsh chemicals. Regular maintenance, such as flushing drains with hot water and using strainers to catch debris, can help prevent future blockages. If you encounter a particularly stubborn blockage or if you’re unsure about how to proceed, don’t hesitate to reach out to a professional plumber for assistance.
