Plumbing conditions in Hawaii
Hawaii has warm year-round with trade-wind rain on windward sides and occasional tropical storms. Many single-wall and post-and-pier homes, plus high-rise condos in Honolulu where one unit's leak can affect several floors.
Freezing weather is rare in Hawaii, so the main plumbing stresses are heat, water chemistry and ground movement rather than frozen pipes.
Hawaii generally has soft to moderately soft water. Scale is less of a problem, but soft, slightly acidic water can be harder on older copper pipes, which can develop pinhole leaks over time.
Common plumbing problems in Hawaii
- Flash flooding on windward slopes
- Salt-air corrosion
- Tropical storms
- Aging drain and sewer lines in older neighborhoods

Cities we serve in Hawaii

Honolulu, HI
Honolulu County
Honolulu has many high-rise condos, where a failed supply line or water heater can leak into several units below, and salt air corrodes exposed pipes.
Hilo, HI
Hawaii County
Hilo is one of the wettest cities in the US, so roof leaks, flash flooding and mold in single-wall homes are frequent issues.
Kailua, HI
Honolulu County
Kailua's windward location brings heavy trade-wind showers and occasional flash flooding in low neighborhoods near the canal.
