Blocked drains are the bread-and-butter of emergency plumbing in Liverpool. From blocked kitchen sinks in the city centre to outside drain blockages in the Wirral, drainage problems affect almost every property at some point. Understanding the causes, costs and prevention helps you deal with the problem efficiently and stop it recurring.
What Causes Blocked Drains in Liverpool?
Fat, Oil and Grease (Kitchen Drains)
The single biggest cause of blocked kitchen drains in Liverpool, and everywhere else. Hot fat poured down the drain cools and solidifies on the inside of the pipe, building up over time into a solid blockage. Never pour cooking fat, oil or grease down the sink. Pour it into a container and bin it when solid.
Wet Wipes and Sanitary Products (Toilets)
Despite what the packaging sometimes claims, wet wipes do not break down in the sewer system. They catch on pipe joints and combine with other debris to form fatbergs: solid masses that block sewers. Only flush toilet paper. Everything else goes in the bin.
Hair and Soap Scum (Bathroom Drains)
Hair and soap residue combine to create sticky blockages in bath, shower and basin drains. Drain guards that catch hair before it enters the drain are inexpensive and effective prevention.
Tree Root Intrusion
Older Liverpool properties often have clay or ceramic underground drains. Tree roots are attracted to the moisture and nutrients inside drains and can crack and infiltrate older pipes. This is a serious blockage requiring CCTV investigation and professional clearing.
Silt and Debris (Outside Drains)
Leaves, grit and general debris accumulate in outside drains and gullies over time, particularly in autumn. Regular clearing prevents complete blockages.
How Are Blocked Drains Cleared?
Most indoor blockages are cleared with a drain rod set or plunger in straightforward cases. More stubborn blockages, particularly in kitchen waste pipes and outdoor drains, respond to high-pressure water jetting (drain jetting), which blasts debris through and leaves the pipe clean. CCTV drain surveys use a small camera to identify the exact nature and location of a blockage, particularly useful for underground drain problems.
How Much Does Drain Unblocking Cost in Liverpool?
A simple blocked indoor drain typically costs £80–£120 to unblock. Stubborn blockages requiring jetting are usually £120–£180. CCTV surveys for underground drain investigation are priced separately depending on the complexity. Jimmy Taps provides fixed prices with free quotes before work starts.
