As September arrives, cooler evenings and rainy days start to return across the UK. With more falling leaves, extra rain, and regular kitchen and bathroom use, blocked drains often become a frequent problem this month.
In this article, we’ll explain why blocked drains are so common in September, what issues to keep an eye on, and what you can do to fix or prevent them.
Why September Brings Drainage Problems
September may not have the heat of summer, but it introduces other factors that put strain on your drainage system:
- Falling leaves and debris: As trees begin to shed, leaves can easily clog outdoor drains.
- Rain showers: More frequent rain can overwhelm drainage systems, especially if there’s a partial blockage.
- Continued kitchen use: As routines settle after the summer, heavy kitchen usage resumes, increasing the risk of grease and food buildup in pipes.
Common Drainage Problems You Might Notice in September
As the weather shifts, your drains may face added pressure. Heavy rainfall, fallen leaves, and changes in daily routines (like the return to school) can all impact how well your drainage system functions.
Here are some typical problems you might start to notice:
Slow-draining water in sinks and bathtubs
If water is draining slowly, it could mean a clog is starting to form from hair, grease, or soap stuck in the pipes.
Gurgling sounds coming from drains
If you hear strange gurgling or bubbling noises after flushing the toilet or using the sink, it may be a sign of trapped air due to a partial blockage. Left untreated, it could lead to a complete clog.
Musty or foul smells
Bad odours from drains are often caused by waste or stagnant water in the pipes, which tend to worsen in damp or rainy conditions.
Outdoor drains overflowing after rainfall
Leaves, dirt, and garden debris can clog external drains, causing water to back up. This overflow can damage property or create safety hazards if not cleared.
How to Prevent Drain Smells and Blockages
Taking a few simple steps this month can help prevent bigger problems later:
- Use drain strainers in sinks and showers to catch hair, food, and debris.
- Clear leaves and mud from around outdoor drains after rain or wind.
- Avoid tipping grease down the kitchen sink – pour it into a container and bin it.
- Flush your drains weekly with boiling water or a baking soda and vinegar mix.
- Have your gutters cleaned to prevent overflow into drainage lines.
These small actions can make a big difference as September’s weather becomes more unpredictable.

Frequently Asked Questions
What causes blocked drains in September?
Falling leaves, increased rainfall, and kitchen waste buildup are all common causes during this month.
Why do my drains smell more in autumn?
Cooler weather can slow down the flow in pipes, while organic debris like leaves and grease starts to break down and create bad odours.
How can I tell if a blockage is serious?
If water is backing up, you smell sewage, or your outdoor drains are overflowing, it’s best to call a professional.
Can I unblock a drain myself?
You can try using boiling water, a plunger, or baking soda and vinegar. If that doesn’t work, you’ll likely need expert help.
When should I call an emergency plumber?
Call if there’s flooding, sewage backup, or water that won’t drain at all, these can cause serious damage if not handled fast.
