Water spilling over the edges of your gutters during rain.

Once the blockage is cleared, the system must be tested.

The anatomy of the problem is deceptively simple. The downpipe is a funnel’s neck, the critical point where the vast catchment area of a roof converges into a single, narrow channel. This very efficiency is its vulnerability. Every autumn, a flotilla of wet leaves descends from the trees; every spring, a diaspora of seeds, moss, and blossom follows. Much of this debris is swept into the gutters, where it lies in wait. A single heavy shower can then compact this material into a sodden, fibrous plug. Less romantic but equally effective blockages come from lost tennis balls, dislodged bird nests, or a gradual accretion of silt and roof grit. In hard-water areas, limescale can slowly narrow the pipe’s bore over years, a silent constriction until one day, it’s complete. The blocked downpipe is thus not a sudden catastrophe but a ticking clock of accumulated small failures.
