"Quick response to call for assistance, professional, great work in my opinion. As far as price, I can't really comment because unless you are extremely familiar with plumbing repairs, price of materials, etc., how would you know what is a fair price? If you have used various repair services in general, you might understand what a "ballpark figure or estimate may be. Bottom line for me is rapid service and very good work."

"What i like about this company was the ability to communicate with the customer. They changed out the flow pump on my solar heater and stuck around to ensure system Was running properly. Watanabe and I along with his assistance which you find me say is sharp guy. Continue to troubleshoot the system and found that I had multiple problems the control valve which maintains hot water temperature throughout the house was bad and needed to be replaced. They located the right valve and we’re back out at my house the following morning to do repairs they conducted a system operational check, hot water heater back up and running to temperature. This is an outstanding company. Wife was extremely happy with their service and so was I highly recommend this company for anyone that has a hot water solar heater true professionals, thank you very much Watanabe."

"All I can say is that Kurt is the best contractor I have found in my 10 years on Oahu. Not only was he timely in responding but was punctual everyday. Kurts craftsmanship is second to none. Decided he didn’t like how one tile looked after completed and took it out even though we would have never noticed it. Kurt also install trim which was done with precision. Kurt is a breath of fresh air in a otherwise hit or miss contractor market."

"had to check a blockage in a drain -- they didn't find anything (for a dishwasher) so I called in the dishwasher appliance repair person -- and they found a blockage in the drain -- ?? Had the plumber do some other minor repairs and checks while he was here and he did a good job. Pricing is good and he was professional and knowledgeable. Would probably use them again -- very nice. But the fact that he didn't find the blockage troubles me a bit."

FAQs for sump pump or interior foundation drains installation projects in Mililani, HI

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
