Let's fix your blocked sink

1. Understanding the Causes of a Blocked Sink


To effectively fix a blocked sink, it's essential to understand the underlying causes. Common culprits include food scraps, grease, soap scum, hair, and foreign objects that accidentally fall into the drain. By identifying the cause, you can determine the appropriate solution for clearing the blockage.


2. Gathering the Necessary Tools


Before you begin fixing the blocked sink, make sure you have the following tools readily available:


  • Plunger

  • Drain snake or auger

  • Bucket

  • Pipe wrench or adjustable pliers

  • Rubber gloves

  • Safety goggles


3. Initial Precautions


To avoid any mess or potential damage, take these precautions:


  • Place a bucket under the sink to catch any water or debris that may come out during the unclogging process.

  • Wear rubber gloves to protect your hands from dirt, bacteria, and potential chemical exposure.

  • Put on safety goggles to shield your eyes from splashes.


4. Attempting Basic Solutions


In some cases, a blocked sink can be resolved with simple solutions. Start by trying the following steps:


  1. Use a flashlight to check for any visible blockage near the drain opening.

  2. Remove the sink stopper or strainer and clean it thoroughly.

  3. Pour boiling water down the drain to dissolve any grease or debris.


5. Using Chemical Drain Cleaners


If basic solutions don't work, you can consider using chemical drain cleaners. However, exercise caution and follow the instructions on the product label. Remember to:


  • Choose a drain cleaner specifically designed for the type of blockage you are facing.

  • Follow the recommended dosage and safety guidelines.

  • Avoid using chemical drain cleaners if you have PVC pipes, as they may cause damage.


6. Employing Natural Remedies


If you prefer more eco-friendly approaches, natural remedies can help unclog a sink effectively. Here are a few options:


  • Baking Soda and Vinegar: Pour a cup of baking soda followed by a cup of vinegar down the drain. Let it sit for a few minutes, then flush with hot water.

  • Salt and Boiling Water: Dissolve half a cup of salt in boiling water and pour it down the drain. This will help break down grease and dissolve minor blockages.

  • Hot Water and Dish Soap: Fill a pot with hot water and add a few tablespoons of dish soap. Pour the solution down the drain to lubricate and dislodge any trapped debris.


7. Applying Plunger Technique


If the blockage persists, it's time to bring out the plunger. Follow these steps:


  1. Fill the sink partially with water to create suction.

  2. Position the plunger over the drain and firmly press down.

  3. Begin plunging vigorously up and down for about a minute.

  4. Remove the plunger and check if the water drains smoothly. Repeat if necessary.


8. Disassembling and Cleaning the P-trap


If the plunger doesn't work, it may be necessary to clean the P-trap, a U-shaped pipe located beneath the sink. Here's how:


  • Place a bucket beneath the P-trap to catch any water.

  • Use a pipe wrench or adjustable pliers to loosen the slip nuts on both ends of the P-trap.

  • Remove the P-trap and clean it thoroughly, removing any debris or blockages.

  • Reassemble the P-trap and check if the sink drains properly.


9. Snaking the Drain


For more stubborn blockages, a drain snake or auger can come in handy. Follow these steps:


  • Insert the snake into the drain and rotate it clockwise while pushing forward.

  • Keep feeding the snake until you feel resistance, indicating the blockage.

  • Rotate and maneuver the snake to break through the clog.

  • Once the clog is dislodged, pull out the snake and test the drainage.


10. Checking the Vent Pipe


If none of the previous methods work, it's possible that the vent pipe connected to your sink is blocked. Consider these steps:


  • Locate the vent pipe on the roof that corresponds to your sink.

  • Inspect the vent pipe for any visible blockages, such as leaves or debris.

  • Use a plumbing snake or a high-pressure water hose to clear the vent pipe.


11. Seeking Professional Assistance


If you've tried all the DIY methods without success, it's time to call in professional plumbers like Blockage Inspectors. Experienced plumbers have the expertise and specialized tools to handle complex blockages and ensure a long-lasting solution.


12. Preventive Measures for Future Blockages


To avoid future sink blockages, follow these preventive measures:


  • Use drain strainers to catch debris and prevent it from entering the drain.

  • Avoid pouring grease, coffee grounds, or food scraps down the sink.

  • Regularly clean the sink stopper, strainer, and P-trap to remove buildup.


FAQs (Frequently Asked Questions)


Can I use a plunger on a double sink?


Yes, you can use a plunger on a double sink. Just make sure to seal the second drain with a wet cloth or sink stopper while plunging the other side.

How often should I clean the P-trap?
