# Summer Drain Problems Explained
When people think about drainage problems, winter usually gets the blame. But summer can actually cause a surprising number of issues for drains and pipework too.
Hot weather, increased water usage, outdoor gatherings, and grease build-up can all put extra pressure on your drainage system during the warmer months.
At Clean A Drain Ltd, we often see an increase in drainage callouts throughout summer — especially preventable problems that start small and quickly get worse.
Here are some of the most common summer drain problems homeowners and businesses face.
---
# # 1. Bad Smells From Drains
One of the biggest complaints during hot weather is unpleasant smells coming from drains.
Higher temperatures can intensify odours trapped inside pipework, especially if there is:
* Grease build-up
* Food waste
* Partial blockages
* Standing water
* Dry drain traps
Outdoor drains and gullies can become particularly noticeable during prolonged warm weather.
# # # How to Help Prevent It
✔ Flush drains regularly with hot water
✔ Keep outdoor drains clear
✔ Avoid pouring fats and oils down sinks
✔ Address slow drainage early

# # 2. Grease and Fat Build-Up
Summer BBQs, outdoor cooking, and increased kitchen use often lead to more grease entering drains.
Although grease may go down the sink as a liquid, it cools and hardens inside pipework, slowly building up over time.
This can eventually lead to:
* Slow draining sinks
* Blocked kitchen drains
* Bad smells
* Complete blockages
# # # Prevention Tip
Instead of pouring grease down the sink:
✅ Let it cool
✅ Pour it into a container
✅ Dispose of it in the bin

# # 3. Increased Drain Usage
During summer holidays and family gatherings, drainage systems often experience much heavier use.
More showers, washing, toilet use, and cooking can place extra strain on drains — especially if there are already small underlying issues developing.
Properties with existing drainage weaknesses may suddenly experience:
* Slow drainage
* Overflowing drains
* Backed-up toilets
* External flooding
---
# # 4. Tree Root Intrusion
Summer is a major growing season for trees and plants.
Tree roots naturally search for moisture and can find their way into cracked or damaged drain pipes underground.
Once inside, roots can:
* Restrict water flow
* Cause recurring blockages
* Crack pipework further
* Lead to expensive repairs if ignored
Recurring drainage problems may sometimes require a CCTV drain survey to properly identify hidden root damage.

# # 5. Summer Storms and Heavy Rain
Although summer brings warm weather, sudden heavy rain and thunderstorms can quickly overwhelm drainage systems.
Blocked outdoor drains combined with heavy rainfall can lead to:
* Flooded gardens
* Overflowing gullies
* Water pooling near properties
* Drain backups
Regular maintenance and keeping outdoor drains clear can significantly reduce the risk.

# # Signs Your Drains May Need Attention
Watch out for:
🚨 Slow draining sinks or showers
🚨 Gurgling sounds
🚨 Unpleasant smells
🚨 Overflowing outdoor drains
🚨 Recurring blockages
🚨 Water backing up unexpectedly
The earlier drainage problems are identified, the easier and cheaper they are usually to fix.
