What salt spray does to equipment
Salt spray gets into fittings, unions, clamps and the casing of pumps and heaters. White crust on a fitting or rust at a bolt is an early warning. Heat pump coils are especially exposed, since they pull air through fins that can corrode.
Rinsing equipment gently with fresh water and keeping it free of debris helps, and so does making sure covers and panels are in place. Pump motor shafts and seals also suffer. If you see drips under a pump, or a heater that leaves rust trails, ask for it to be checked.
