Sewer gas smell in house — Barcelona, Catalonia
A rotten-egg or sulfur smell inside your home usually means sewer gas is escaping through a dried-out trap, cracked drain pipe, or failing wax ring on a toilet. Sewer gas contains methane and hydrogen sulfide, which are unpleasant and potentially hazardous in high concentrations. A licensed plumber can locate the source, restore trap seals, replace damaged components, and ensure your venting system is working properly.
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.
