Backflow preventer leaking — Barcelona, Catalonia
A leaking backflow preventer can waste water, cause low pressure, and — if it fails completely — allow contaminated water to flow back into your drinking supply. Most municipalities require annual testing, and a licensed plumber can repair or replace the device to keep your home compliant and safe.
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.
