What We Do
Our Sump Pump Services
We handle every aspect of sump pump systems — from first install to emergency replacement.
Sump Pump Installation
We assess your drainage situation and install the right pump for the job — submersible or pedestal — sized for your specific water intrusion volume and discharge requirements.
Sump Pump Repair
Float switch failures, motor burnout, discharge line blockages — we diagnose and repair all common sump pump failures quickly to restore flood protection.
Sump Pump Replacement
Pumps typically last 7–10 years. When repair doesn't make sense, we replace your unit with a modern, reliable pump and test the full system before leaving.
Battery Backup Systems
Power outages often happen during the same storms that cause flooding. A battery backup sump pump keeps your property protected when you need it most.
Sewage Ejector Pumps
For below-grade bathrooms and laundry rooms, sewage ejector pumps move waste up to the main drain line. We install and service ejector pump systems.
Annual Pump Maintenance
Regular testing and cleaning extends pump life and catches problems before they become emergencies. We offer annual maintenance visits to inspect and test your system.

Common Questions
Frequently Asked Questions
Do I need a sump pump in Hawaii?
Not every property needs one, but many do — especially homes in low-lying areas, near streams, or with high water tables. O'ahu's intense rainfall events can overwhelm drainage quickly. If you've experienced water intrusion in a crawl space, basement, or garage, a sump pump is often the right long-term solution.
How long do sump pumps last?
Most residential sump pumps last 7–10 years with normal use. Heavy use during frequent rain events, running dry, or cycling continuously shortens the lifespan. We recommend testing your pump every spring and replacing it proactively if it's over 8 years old.
What's the difference between a submersible and pedestal sump pump?
A submersible pump sits inside the pit and is submerged during operation — it's quieter and better for heavy water volumes. A pedestal pump has its motor mounted above the pit — it's less expensive and easier to service but noisier. For most residential applications we recommend submersible pumps.
Do I really need a battery backup?
Yes, especially in Hawaii. Power outages frequently accompany the storms and heavy rain that cause flooding in the first place. Without backup power, your primary pump is useless exactly when you need it. A battery backup system provides 24–48 hours of protection during an outage.
What should I do if my sump pump fails during a storm?
Call us at 808-847-5414 — our emergency line is available 24/7. In the meantime, if you have a wet/dry vacuum you can manually remove water to reduce flooding while you wait. Do not enter standing water near electrical panels or outlets.
