Blocked drains are a common problem and can lead to unpleasant smells, slow drainage and even flooding if not dealt with. Understanding the causes can help homeowners prevent issues before they become serious.
One of the most common causes is fat, oil and grease build-up
When poured down sinks, these substances cool and harden inside the pipes, narrowing the passage until water can no longer flow. Over time, this can create blockages that are difficult to remove without professional help.
Food waste is a contributor
This happens particularly in kitchen drains. Items such as rice, pasta and peelings can swell or clump together in pipes, even when a waste disposal unit is fitted. These materials can easily become trapped and cause obstructions.

Hair and soap residue are frequent causes of blocked bathroom drains
Hair binds with soap scum and shampoo residue, forming tangles that restrict water flow. This type of blockage often develops slowly.
Foreign objects flushed down toilets can create problems
Items such as wet wipes and sanitary products, do not break down like toilet roll and can lead to blockages. Plastic wipes don’t disintegrate when flushed down the toilet, so when oil and fat congeal, so-called fatbergs form in sewers.
Tree root intrusion is a common issue in drains
This can happen, especially in older properties. Roots are attracted to moisture and can enter through cracks in pipes, causing blockages or structural damage.
