Unique Plumbing Needs on Oahu


Living on Oahu is a privilege, but it’s not without its challenges. Since the climate on the island of Oahu can change in an instant, we always have to be vigilant. It can be blazing hot and sunny one minute and pouring rain the next! We also try to protect our precious environment by being energy efficient and eco-conscious. Therefore, we understand that the residents of Oahu have unique plumbing needs. These include:


  • Durable pipes, installed correctly, that can handle large amounts of rainfall.
  • Frequent piping and plumbing inspections with leak detection to ensure there is no water damage.
  • Water heaters that are installed properly and doing their jobs effectively
  • Drainage systems that can easily remove large quantities of water from a home or business
  • Efficient appliances that use as little energy and water as possible.


“Our focus is to ensure customer satisfaction by going beyond the call.”

Shane Mizusawa, Owner
