Fat build up from a drain pipe

Blocked drains are a common issue for homeowners, but don’t worry, there are a few DIY methods you can try to clear the blockage yourself before getting us out.

We understand that the cost of living may encourage you to save on unexpected plumbing costs, and with a little patience and the right tools, you might just be able to fix the issue on your own. Here are 4 simple and effective tips to unblock a drain before needing to reach out to a professional plumber.



1. Use a Plunger


One of the most straightforward and effective DIY tips to unblock a drain is by using a plunger. It’s ideal for minor blockages in sinks, toilets, or showers. The suction created by the plunger can dislodge whatever is causing the blockage, whether it's food debris, hair, or soap buildup, don't forget to block off any overflow holes.


How to Use a Plunger:

- Make sure there’s enough water in the sink or tub to cover the plunger’s bell.

- Place the plunger over the drain and press down to create a tight seal.

- Block off any overflow holes.

- Pump the plunger up and down rapidly several times to create suction and force the blockage free.

- After a few tries, lift the plunger and see if the water begins to drain. If it does, you've successfully cleared the blockage.


Pro tip: Always make sure to clean the plunger after use to avoid spreading bacteria or grime. 



2. Use a Drain Snake or Auger


For more stubborn blockages, a drain snake (or auger) is a handy tool that can help you reach deep into the pipe and break up or pull out the obstruction. Drain snakes are available in various sizes and can be found at most hardware stores.

How to Use a Drain Snake:

- Insert the end of the snake into the drain and start feeding it down into the pipe.

- Turn the handle to rotate the snake, allowing it to move through the drain and grab onto the blockage.

- Once the snake feels like it’s caught the obstruction, gently pull it back out.

- Flush the drain with hot water to clear any remaining debris.


Pro tip: If you’re dealing with a particularly tough blockage, consider renting a motorised drain auger. These are more powerful and can tackle deeper blockages.



3. Try a Wet/Dry Vacuum


If you have a wet/dry vacuum at home, it can be a great tool for removing a clog. This method works best for drains that are clogged with solids like hair, debris, or small objects that are stuck in the pipe.


How to Use a Wet/Dry Vacuum:

- Set the vacuum to its liquid mode.

- Create a tight seal over the drain opening using a rag or towel.

- Turn on the vacuum to its highest suction setting.

- The vacuum will suck out the clog and any standing water in the drain.


Pro tip: Be cautious when using this method, as the vacuum can get messy if not sealed properly. Always wear gloves and keep towels nearby to clean up any spills.



4. Use a Boiling Water Flush


This method may only work on issues where the fixture is slow draining. Sometimes, all a drain needs is a good flush of hot water to clear away grease or soap scum that has built up over time. This method is especially useful for kitchen sinks that have grease-related blockages.


How to Use Boiling Water:

- Boil a kettle or large pot of water.

- Slowly pour the boiling water down the drain in stages, allowing it to sit for a few seconds between each pour.

- Repeat the process several times, depending on the severity of the blockage.


Pro tip: This method works best for mild blockages and can be used regularly as a preventative measure to maintain your drains.

While the above methods can resolve a few common blockages, there are times when a blockage may be too severe for DIY fixes. If you’ve tried all of these methods and the drain is still clogged, it could be a sign of a more serious issue, such as inadequate venting, damaged pipes, or a major buildup further down the plumbing system.
