Common Causes of Blocked Drains

Understanding what causes blockages can help you avoid them. Here are the most frequent reasons drains block in Exmouth and East Devon.

Fat, Oil & Grease Buildup

Cooking fat and grease solidify inside pipes, gradually narrowing them until water can no longer pass through. This is one of the most common causes of blocked kitchen drains in Exmouth.

Hair Accumulation

Hair binds with soap scum and grease to form stubborn clogs, particularly in bathroom drains and shower traps.

Food Waste & Debris

Food scraps, coffee grounds and other kitchen waste build up over time, especially in properties without sink strainers.

Tree Root Intrusion

Tree roots seek out moisture and can penetrate tiny cracks in drainage pipes, eventually causing major blockages. Common in Exmouth gardens with mature trees.

Foreign Objects

Wet wipes, sanitary products, cotton buds and toys flushed down toilets are a leading cause of drain blockages that require professional clearance.

Soap & Mineral Deposits

Soap scum combines with minerals in hard water to leave a residue that narrows pipes over time, reducing water flow.

Collapsed or Damaged Pipes

Many older Exmouth properties have clay or cast iron drainage pipes that crack, collapse or become misaligned over the years, causing persistent blockages.

DIY vs Professional Drain Clearance

Some blockages are simple enough to tackle yourself, but others need a professional. Here is how to tell the difference.

Try Yourself First

For minor blockages in kitchen sinks, bathroom basins or shower drains, these DIY methods are worth trying before calling a plumber.

Use a plunger on the affected drain — create a tight seal and pump firmly
Try a drain snake or wire to dislodge the blockage physically
Pour baking soda followed by white vinegar, wait 30 minutes, then flush with boiling water
Run boiling water slowly down the drain to clear minor grease buildup

Call a Professional

If you notice any of the following signs, it is time to call a local drain specialist. Delaying can lead to more expensive repairs.

Multiple drains are blocked at the same time
An outdoor drain or manhole is overflowing
There is a bad smell coming from your drains
Water is backing up into sinks, baths or toilets
The blockage keeps coming back after DIY attempts
You suspect a collapsed or damaged pipe

CCTV Drain Surveys

A CCTV drain survey involves feeding a small waterproof camera through your drainage system to inspect the condition of the pipes from the inside. The camera sends live footage to a monitor, allowing the engineer to identify exactly what is causing the problem without any excavation.

You should consider a CCTV drain survey if you are experiencing recurring blockages, suspect tree root intrusion, or are buying a property in Exmouth and want to check the drainage before committing. Many older East Devon properties have ageing clay or cast iron pipes that are prone to cracking and collapse.

A typical CCTV drain survey in the Exmouth area costs between £100 and £250. The engineer will provide a report with footage and recommendations. If repairs are needed, having a survey first means the work can be targeted precisely, saving you money in the long run.

How to Prevent Blocked Drains

Prevention is always cheaper than a callout. Follow these practical tips to keep your drains flowing freely.

Never Pour Fat Down the Sink

Let cooking fat cool and solidify, then scrape it into the bin. Even small amounts of grease build up inside pipes over time.

Use Drain Guards

Fit mesh drain guards over plugholes in the kitchen and bathroom to catch hair, food scraps and other debris before they enter the pipe.

Run Hot Water After Washing Up

After doing the dishes, run hot water for 30 seconds to help flush any remaining grease through the system.

Don't Flush Wet Wipes

Even wipes labelled "flushable" do not break down like toilet paper. Bin them instead to avoid blockages further down the line.

Use Enzyme-Based Drain Cleaner

A monthly treatment with an enzyme-based drain cleaner helps break down organic buildup before it becomes a problem. Avoid harsh chemical cleaners that can damage pipes.

Keep Trees Trimmed Near Drains

If you have trees near your drainage runs, have the roots checked periodically. Root intrusion is a common issue in East Devon properties with mature gardens.
