Sewer backup — Barcelona, Catalonia
A sewer backup pushes wastewater back into your home through drains, toilets, or basement floor drains. It poses serious health risks from bacteria and can cause extensive water damage. A licensed plumber can locate the blockage, clear the main sewer line, and recommend preventive measures like backflow valves.
Waarom dit veel voorkomt in Barcelona
Barcelona's dense Eixample apartment stock dates largely from the early 1900s, with cast-iron drainage and galvanised supply lines threaded through shared light wells (patis de llum) that make leaks slow to trace and disruptive to neighbours. Mediterranean humidity and hard tap water accelerate limescale and corrosion, and risers in heritage buildings often cannot be re-routed without llicència d'obres clearance.
