Taps wear faster on the island, and in a rental they take more handling than they would at home.
Salt gets everywhere
Even indoors, salt in the air works on chrome, brass and the internals of taps. Cartridges seize and finishes pit sooner than the manufacturer intended. A cartridge replacement usually restores a tap completely.
Quality fittings are worth repairing
Many homes and villas here have good tapware where a rebuild kit restores it properly. We would rather repair a decent fixture than sell you a replacement, and we will tell you honestly which situation you are in.
Poor pressure at one tap
Nearly always the small screen in the end of the spout, and here it is often salt deposits as much as scale. Unscrew it, soak it in vinegar overnight, refit it.
Outside taps need better parts
Hose bibs and outdoor shower taps fail here far more often than indoor ones. Something specified for coastal use costs a little more and lasts several times longer.
