Plumbing service in Hawaii
Call NowHawaii plumbing deals with salt air, termites, older single-wall homes, catchment water systems on some islands and cesspools that the state is phasing out.
Hawaii weather and your plumbing
Hawaii is warm year-round at sea level, so freezing is not a concern outside high elevations. Trade winds carry salt air that corrodes exposed fixtures and metal piping, and windward sides get much more rain than leeward sides.
Season by season in Hawaii
- Wet season
- From roughly October through April, heavy rain on windward slopes floods drainage and can affect cesspools and septic systems.
- Dry season
- Leeward areas get very little rain, and catchment households may need to manage stored water carefully.
Problems the Hawaii climate causes
Corrosion of exposed plumbing
Cause: Salt-laden trade winds.
Result: Outdoor fixtures, valves and metal lines corrode quickly near the coast.
Do: Ask about corrosion-resistant fittings and inspect outdoor plumbing regularly.
Cesspool problems
Cause: Heavy rain and high groundwater.
Result: Older cesspools overflow or fail.
Do: State law calls for cesspools to be upgraded over time; a plumber or septic professional can explain the options.
Housing in Hawaii
Many Hawaii homes are single-wall wood construction on post-and-pier foundations, which leaves plumbing exposed underneath. Some rural homes on the Big Island and Kauai rely on rainwater catchment, and a large number of properties statewide still use cesspools.

Hawaii questions
Does Hawaii require cesspool upgrades?
State law calls for cesspools to be replaced or upgraded by a set deadline. A licensed professional can explain what applies to your property.
Why do outdoor faucets corrode so fast near the beach?
Salt air speeds up corrosion. Brass and stainless fittings hold up better than plain steel.
How do I check a plumber's license in Hawaii?
Plumbers in Hawaii are licensed by the Board of Electricians and Plumbers under the Department of Commerce and Consumer Affairs. Plumber licenses renew every three years. Contractors also need a contractor license from the state's Contractors License Board.
