UK drain unblocker guide
Diagnose a blocked sink, toilet, waste pipe, outside drain or underground drainage problem using UK terminology, products and professional services.
Start with the problemChoose a pathway
What is blocked?
Start with the affected fixture, then check whether the symptoms appear anywhere else.
Products
Liquids, gels and maintenance treatments
Compare chemistry, suitable blockage types, pipe compatibility, usage limits and safety information before choosing a product.DIY tools
Sink plungers, hand augers and drain rods
Match the tool to the fixture and understand the point at which more force can damage pipework or push the blockage deeper.Professional help
Drain jetting, CCTV drain surveys, Picote cleaning and drain relining
A professional service should match the suspected cause. Clearing restores flow; inspection establishes why it blocked; repair addresses defects that make the problem return.
Information to give the engineer
- Which fixtures are affected
- Whether the problem is slow, fully blocked or backing up
- What tools or products have already been used
- Whether the same blockage has happened before
