The coastal problem
Salt air plus humidity accelerates corrosion of metal parts and keeps crawl spaces damp. Small leaks can go unnoticed for months.
What to check
Look at exposed fittings, hose bibs, water heater connections and under sink supply lines. Rust, white crust or a musty smell are all clues.
Protect crawl spaces
Keep the crawl space dry and ventilated, and consider a vapor barrier and dehumidifier as part of a broader moisture plan.
Vacation homes and rentals
If a home sits empty, shut off the main or have a plumber check it between guests. A slow leak in an unoccupied house can run for weeks.
Materials
PEX and CPVC resist corrosion better than older metal pipe in many applications.
