Water heater pilot light out — Barcelona, Catalonia
A gas water heater that has lost its pilot light will stop producing hot water. Common causes include a faulty thermocouple, a dirty pilot orifice, or a draft blowing out the flame. While relighting the pilot is sometimes a simple DIY fix, repeated outages indicate a component failure that requires a licensed plumber or gas technician.
Why this is common 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.
