Kitchen sink leaking underneath — Alicante, Valencian Community
Water pooling inside the cabinet beneath a kitchen sink is one of the most common plumbing problems in any home, and because it is hidden behind cabinet doors, it often goes unnoticed until mold, warped wood, or a musty smell gives it away. The leak can originate from several points: worn-out compression fittings or corroded shut-off valves on the hot and cold supply lines, loose slip-nut connections on the P-trap or tailpiece, a failed gasket between the sink basin and the drain flange, or cracked seals around a garbage disposal unit. Even a slow drip — just a few drops per minute — can saturate the cabinet floor, delaminate particleboard, and create an ideal environment for mold growth within days. A plumber can typically diagnose and repair the leak in under an hour ($150–$300 for a service call), with parts rarely exceeding $30–$50. Replacing corroded supply lines with braided stainless-steel hoses ($10–$20 each) during the repair is a smart preventive upgrade.
Waarom dit veel voorkomt in Alicante
Alicante's rapid post-Franco construction boom produced large amounts of housing with PVC and copper plumbing that is now 40–50 years old and prone to joint failure. The city's hard calcareous Mediterranean water causes severe limescale buildup in water heaters and boilers, requiring more frequent descaling than inland Spain. Sea-facing properties experience salt corrosion in exposed copper fittings and valve bodies.
