Blocked drain investigation in Great Sankey

Blocked drain investigation — how it works here

A drain that keeps blocking is not a blockage problem, it is a condition problem. Something is holding material back — a dip that has lost its fall, a joint that has opened, a pipe deformed under a driveway, or roots at a cracked section. Rodding and jetting move what has collected. They leave the reason it collects exactly where it was, which is why the gap between visits gets shorter each time. In WA5 the cause splits neatly by age. On the newer estates it is almost always mechanical: crushed plastic under block paving, a back-falling run, or building debris that was never flushed out. Around Sankey Bridges, Penketh and Bewsey it is the older story — open clay joints, brick sections with dropped inverts, and groundwater getting in below the water table. We survey first so you see the cause on camera, then you decide once instead of every few months.

• Camera goes in before anything is cleared, so the cause is on the footage
• Distinguishes a genuine blockage from a deformed or back-falling pipe
• Deformation, standing water and open joints all measured, not guessed at
• Defect position marked on the surface so nobody digs a trench hunting
• Report works whoever does the repair — us, your plumber, or United Utilities
