Storm season can bring heavy rainfall, strong winds, and unexpected drainage problems for homeowners and businesses alike. One of the most common issues during wet weather is blocked drains. When drains become clogged, water cannot flow freely, leading to flooding, unpleasant smells, and even structural damage to your property. Understanding the causes of blocked drains and knowing a few quick fixes can help you avoid costly repairs and keep your drainage system functioning efficiently throughout the season.
Why Storm Season Causes Drain Problems
During storms, drains are forced to handle a much larger volume of water than usual. Leaves, dirt, branches, and debris are often washed into gutters and underground drainage systems. The ongoing buildup inside the drain can restrict the smooth flow of rainwater. In older drainage systems, cracks and tree root intrusion can make the problem even worse.
Heavy rain can also wash grease, mud, and litter into outdoor drains, creating stubborn blockages. If these obstructions are not cleared quickly, water can back up into sinks, toilets, driveways, or gardens.
Homeowners in areas with frequent rainfall often rely on professional services such as Drain JettingDorking to clear stubborn debris and restore proper water flow before severe damage occurs.
Common Causes of Blocked Drains During Storms
1. Leaves and Garden Debris
Fallen leaves are one of the biggest causes of storm-related drain blockages. Gutters and outdoor drains easily become clogged when leaves
mix with rainwater and form compact masses.
2. Mud and Silt Build-Up
Heavy rain can wash mud and soil into drainage systems. Over time, this sediment settles inside pipes, reducing the space available for water to pass through.
3. Tree Root Intrusion
Tree roots naturally seek moisture and may enter small cracks in underground pipes. Once inside, roots continue to grow, causing severe obstructions and pipe damage.
4. Fat, Oil, and Grease
Many households unknowingly pour cooking grease down sinks. During storm season, increased water pressure can move these substances through pipes where they harden and combine with debris, forming solid blockages.
5. Damaged or Collapsed Pipes
Older drainage systems are especially vulnerable during storms. Excess pressure from heavy rainfall can worsen existing cracks or even collapse weakened pipes completely.
Warning Signs of a Blocked Drain
Recognising early warning signs can help prevent a minor blockage from turning into a major drainage emergency. Watch for:
- Slow draining sinks or bathtubs
- Gurgling noises from pipes
- Unpleasant odours near drains
- Overflowing outdoor drains
- Water pooling around your property
- Toilets struggling to flush properly
If you notice these issues during storm season, it is important to act quickly before flooding or water damage develops.
Quick Fixes for Blocked Drains
Remove Visible Debris
Start by checking outdoor drains and gutters for leaves, twigs, or rubbish. Put on protective gloves and carefully clear away leaves, dirt, or other visible waste from the drain area to help restore proper water flow.
Flush with Hot Water
For minor grease-related clogs, pouring hot water down the drain may help break down the blockage. Avoid boiling water if you have plastic pipes, as excessive heat could damage them.
Use a Plunger
A plunger can be effective for clearing small sink or toilet blockages. The suction pressure helps loosen debris trapped in the pipes.
Try a Drain Snake
A drain snake or auger can reach deeper blockages inside pipes. Gently feed the drain tool into the pipe and twist it slowly to remove trapped debris and buildup.
Clean Gutters Regularly
Regular gutter cleaning before and throughout storm season helps prevent leaves and waste from entering the drainage system. This simple maintenance step can prevent many drainage issues.
Call a Professional Drain Specialist
Some blockages are too severe for DIY methods. Persistent flooding, recurring clogs, or foul odours may indicate a deeper issue within the drainage network. Professional services can inspect and clear the system using advanced equipment such as high-pressure water jetting and CCTV drain surveys.
