How to Stop Mud and Leaves from Blocking Your Drain

How to Stop Mud and Leaves from Blocking Your Drain

With falling leaves, heavy rain, and muddy conditions, the autumn and winter months can be a particularly hard time for domestic and commercial property owners.   

You may have noticed your outside drain clogged with leaves and mud, which can build up over time. Without addressing this quickly, it can lead to overflowing, bad odours, and damage to your property.   

In our guide, we explore why it happens, the signs and ways to prevent mud and leaf build up, and how we can help.   

What Causes Outdoor Drain Build Up?

Mud and leaves blocking drains are a common seasonal issue, particularly in windy and wet conditions. Here are a few ways in which mud and leaves find their way into your outside drains:

Leaves

Leaves, twigs, and debris can be swept away in the wind and gather around your outdoor drains. If it isn’t maintained and cleared, the build-up can cause blockages both inside and outside of the drain. 

Mud

Following heavy rainfall, mud can appear around your property, and the silt and soil can be washed into your outside drain. Over time, an outdoor drain clogged with mud can harden and build up, making it harder for water to flow through as usual.

Tree Roots

As trees look for sources of water to thrive, their roots can grow into your outside drains and pipes. This can cause cracks and breakages in your systems, letting in debris and soil in the process.

How to Spot Signs of Mud and Leaf Build Up

During the autumn and winter months, it’s important to watch out for signs of leaf and mud build up, including:

Overflowing and Water Pooling

Overspilling and pooling near your drain can be one of the most obvious signs of clogged mud and debris, as it can indicate that there is a problem beneath the surface.

Slow Draining

Water that appears to be draining more slowly than usual, even after rainfall, can show debris build up in outdoor drains.

Bubbling Sounds

Gurgling noises being caused by water and air that are struggling to pass through the drains as intended. This can point towards general clogging in the system.

Unpleasant Odours

Bad or unpleasant odours occurring when there is a blockage in your drainage system. The smell can be the result of trapped food waste or standing water that is struggling to make its way through.

How to Fix Blockages from Mud and Leaves

To prevent clogged drains, it’s important to regularly check and maintain your drainage systems. Before starting, we recommend using gloves to protect your hands from harsh chemicals.

Here are just a few steps to follow to ensure that they remain clear so that water passes through:

  1. Clear Debris:
  2. Start by removing any visible leaves, twigs, and debris from the surface of the drain. Make sure to take care throughout this stage, as there may be sharp objects.

  3. Remove Mud
  4. If you notice mud in your drains, make sure to scoop it out with a trowel. When doing this, make sure not to push it further into the drain, as this can worsen the blockage. 

  5. Use a Drain Rod
  6. If you have a drain rod, insert it into the drain and twist it clockwise to break up the leaves and mud within the pipes. Continue doing this until the water begins to pass through more easily. 

  7. Flush the Drain
  8. Use a hose or pour a warm, not hot, bucket of water into the drain to flush out any remaining debris. Do this until it starts to break down. 

What Preventative Maintenance is Recommended?

It’s important to take preventive action to stop leaves and mud from building up in the future. 

Install Drain Guards

Drain guards are designed to fit over your drain to prevent leaves and debris from clogging and pollutants from entering your water system. Make sure to clear the guards regularly, as these can still become blocked over time. 

Inspect Drains

Regardless of whether your drain is near grass or trees, we recommend inspecting it regularly to ensure that they are clear. This will also help you spot overspilling quickly.

Clear Drains Regularly

During autumn, make sure to regularly clear your drains and sweep any leaves and mud across the outside of your property. Doing this early will allow you to prevent it from entering your drains.
