How To Unclog Basement Drain: Step-by-Step Guide - FS Drainage

February 26, 2024

Dealing with a clogged basement drain can be a daunting task, especially if you're not sure where to start. Not only can a blocked drain cause water to back up - potentially leading to flooding and water damage - but it can also be a source of unpleasant odours and even health hazards if not addressed promptly.

Fortunately, unclogging a basement drain is often a task you can tackle yourself with the right tools and techniques - but where’s the best place to start? In this guide, we're going to walk you through the steps to clear your basement drain effectively, ensuring your drainage system functions properly once again. Let’s dive in!

Common Causes of Basement Drain Clogs

So, what causes a basement drain clog? The following are some of the most common culprits:

Accumulation of Debris

One of the most common reasons for a basement drain clog is the accumulation of debris, such as dirt, dust, and small objects that can easily find their way down the drain. Over time, this accumulation can form a blockage, restricting water flow and leading to backups.

Tree Root Intrusion

Another potential cause of basement drain clogs, particularly in older homes, is tree root intrusion; tree roots can grow into pipes through tiny cracks or joints in search of water, eventually obstructing the flow of water and causing significant blockages that are often incredibly difficult to get rid of manually.

Grease and Soap Scum

Grease from kitchen sinks and soap scum from your washing machine and bathroom drains can also contribute to basement drain clogs; these substances can stick to the walls of the pipes, gradually building up and narrowing the passage for water to flow through.

Unclogging Your Basement Drain: Tools and Materials Needed

So, before you begin the process of unclogging your basement drain, it's important to gather all the necessary tools and materials. Having the following tools on-hand will help ensure that you can work efficiently and effectively:

Plunger

A good-quality plunger is essential for any attempt to unclog a drain - ensure that you have one that can create a strong seal around the drain opening for optimal effectiveness.

Plumbing Snake or Auger

For more stubborn clogs, a plumbing snake or auger can be a valuable tool, as it allows you to reach deeper into the drain to break up or retrieve blockages that can't be addressed with a plunger alone.

Bucket and Towels

As we’d recommend with any DIY plumbing operation, always have a bucket and several towels on hand to manage any water that spills or needs to be drained from the pipe.

Preparation

Before tackling the clog, it's important to prepare the area: begin by removing any standing water with a bucket and towels, and clear the space around the drain to ensure you have easy access.

Plunging Technique

Next up, start with the plunging technique: place the plunger over the drain opening and push down firmly, then pull up sharply. Repeat this motion several times to try to dislodge the clog through suction.

Use of Plumbing Snake

If plunging doesn't resolve the clog, it's time to use a plumbing snake - but you’ll need to ensure you do this carefully to avoid causing further damage! Carefully feed the snake into the drain until you meet resistance, then turn the handle to break up or hook the clog so you can pull it out. If you’re met with resistance, don’t force.

Flushing with Hot Water

Once you’ve successfully removed the clog, flush the drain with hot water - hot water is a great way to naturally clean your drains, and helps by lifting small blockages and washing away any remaining debris. In fact, regularly flushing your drains with hot water is pretty much the closest you can get to self cleaning drains - and best of all, it’s totally free!

Prevention Tips

Like with any plumbing issue, prevention is the key to ensuring minimal maintenance is required on your part. Regularly cleaning your drains and avoiding the disposal of grease, large food particles, and non-flushable items down the drain can significantly reduce the risk of clogs.

If you're experiencing recurring issues or if the clog seems beyond your ability to fix, it may be time to seek professional help. For those in need of expert drainage services in West London, reaching out to a professional can provide a quick and effective resolution to your drainage problems.

Signs of Successful Unclogging

So, how do you know you’ve successfully unclogged your basement drain? Here are some signs to look out for:

Improved Drainage

The most immediate sign of a successfully unclogged drain is improved water flow. After completing the unclogging process, run water down the drain to observe its speed; if the water flows smoothly without pooling or backing up, it's a good indication that you've removed the blockage.

Noises in Pipes

As odd as it may sound, listening to the noises your pipes make can also be a good indicator; a gurgling sound as water flows down the drain can often mean the clog has been cleared and the water is moving through the pipes as it should.

When to Seek Professional Help

Despite your best efforts, some clogs can be stubborn and simply refuse to budge - or there may be underlying issues with your plumbing that require professional attention. In the following situations, it's a good idea to call in the experts:

  • Recurring Clogs: If the same drain keeps getting clogged - especially after multiple attempts to clear it - there could be a deeper issue, such as structural problems with the pipes or a more significant blockage further down the line.
  • Water Damage: If you notice water damage or signs of leakage in the walls, floors, or ceilings around your basement drain, it's crucial to call in professional plumbers immediately. Water damage can lead to mould, mildew, and structural issues if not addressed promptly.
  • No Improvement: If after trying all the DIY methods, there's no improvement in drainage, it's time to seek help. Professional plumbers have specialised tools and cameras that can diagnose the issue quickly and efficiently.
