We respond within minutes
O'ahu is a small island in geography but enormous in variety. The plumbing challenges facing a homeowner in Hawaii Kai are different from those in a Mililani townhome, which are different again from a historic property in Kalihi or a west-side home on Hawaiian Home Lands in Nanakuli. Most plumbing companies base their coverage on what is convenient for them. Alpha Omega Plumbing Inc has taken a different approach since 2014: we go wherever the job is, because that is what O'ahu homeowners deserve.
Whether you need a drain cleaned, a water heater replaced, a septic system serviced, or emergency plumbing at 3 a.m., we are ready to respond. Our team is licensed, insured, and experienced with the full range of conditions you find across this island — coastal salt air, mineral-heavy water, aging pipe materials, and private septic systems. Call us at (808) 847-5414 or submit a request online and we will get back to you quickly.
What We Offer
Plumbing Services for O'ahu Homes and Businesses
From Kahala Beach to the Waianae coast, from Pearl City to the North Shore, the plumbing needs across O'ahu are as varied as the island itself. Older homes in historic neighborhoods may still carry galvanized supply lines. Coastal properties face accelerated corrosion from salt air. Properties in rural areas and Hawaiian Home Lands often rely on private septic rather than municipal sewer. Our team has worked across the full island for over a decade and knows what to expect. Here is what Alpha Omega Plumbing offers O'ahu residents and businesses:
Drain Cleaning
Slow drains, stubborn backups, and blocked sewer lines are among the most common calls we receive. Our professional drain cleaning service uses industrial-grade equipment to clear blockages thoroughly without damaging your pipes. We handle kitchen drains, bathroom lines, laundry connections, and full sewer jetting for properties with root intrusion or heavy buildup. Available island-wide.
Emergency Plumbing
Burst pipes, sewage backups, and flooding emergencies do not follow a business schedule. Our 24/7 emergency plumbing service covers the entire island. When something goes wrong at 2 a.m., call (808) 847-5414 and a licensed plumber will be dispatched. We know the roads across O'ahu and we will get to you — no matter which side of the island you are on.
Septic System Service
A significant portion of O'ahu properties — particularly on the west side, in rural areas, and on Hawaiian Home Lands — rely on private septic systems. Alpha Omega handles septic pumping, inspections, and repairs across the island. We recommend pumping every three to five years for most households — regular maintenance is far less expensive than an emergency system failure. We will assess your system honestly and tell you exactly what it needs.
Water Heater Service
When your hot water disappears, our licensed technicians repair and replace all types of water heaters — tank, tankless, and solar. We carry common parts so most jobs are completed in a single visit. Hawaii's mineral-heavy water supply accelerates sediment buildup and shortens heater life, so periodic flushing is worth doing even when the unit seems to be working fine. Call us for a free online estimate on repair or replacement.
Additional Services
Our team also handles sewer line repair and replacement, pipe repiping, leak detection, hydro jetting, water filtration installation, faucet and fixture repair, water shut-off valve service, and more. No matter the scope of the job, you will get a clear explanation of what is needed and a written estimate before any work begins. No surprises, no pressure.
How It Works
Our Step-by-Step Process
We have built our process around what O'ahu homeowners actually want — clear communication, no surprises, and a plumber who treats your home with care, wherever you are on the island.
Call or Request Service Online
Reach us any time at (808) 847-5414 or submit a service request online. If it is an emergency, call — we respond to phone calls immediately, day or night, and dispatch anywhere on O'ahu. For non-urgent work, fill out the form on our website and we will follow up within a few hours.
Describe the Problem
When you call, tell us what is going on. The more detail you can give — when the problem started, what you have noticed, whether it is getting worse — the better prepared our plumber will be before arriving. This helps us bring the right tools and parts on the first visit and avoid unnecessary delays.
Schedule the Visit
We will find a time that works for you. For same-day calls, we will give you an arrival window and call ahead before we leave. We serve the full island, so we will give you an honest travel estimate based on your location. We respect your time and do our best to show up when we say we will.
Assess and Estimate
Our plumber will inspect the issue and walk you through what they find. You will get a clear, written estimate before any work starts. We do not begin until you have approved it — no pressure, no surprises, no upselling you on work that is not actually needed.
Complete the Work
Once you approve, we get to work. Our team brings professional equipment and quality parts. We protect your floors, clean up after the job, and make sure everything is running properly before we leave. If a problem turns out to be more complex than expected, we will tell you before continuing.
Final Walkthrough
Before we wrap up, we walk you through what was done and answer any questions you have. If there is anything else we noticed during the visit that might need attention, we will let you know — without pressure.

Why Choose Us
Why O'ahu Homeowners Choose Alpha Omega Plumbing
A lot of plumbing companies on O'ahu are selective about where they will travel. Some will not go past Pearl City. Others add fees for the west side or the windward coast. Alpha Omega Plumbing has always been different: we cover the full island, at the same standard of service, regardless of your zip code. Here is why that matters.
Licensed and Insured
Every technician is fully licensed by the State of Hawaii and insured. We carry general liability and workers compensation, so you are fully protected on every job, from minor repairs to major system replacements.

Upfront, Transparent Pricing
You will know what the job costs before we start. The price we quote is the price you pay — no surprise charges when the invoice arrives, and no fees based on which side of the island you live on.
When you call Alpha Omega Plumbing, you are getting a company that means it when we say we serve all of O'ahu.

Our Community
Why We Love Working on O'ahu
After more than a decade of driving every highway and back road on this island, O'ahu never stops being remarkable. Every service call takes us somewhere new — a new neighborhood, a new view, a new homeowner who trusts us with their home. That is a responsibility we take seriously, and it is one of the reasons this work still means something to our team.
Diamond Head (Leʻahi)
The iconic volcanic tuff cone that has become the symbol of Honolulu and Oʻahu itself. Whether we are heading out to Hawaii Kai or coming back through Waikiki, Diamond Head is always there on the horizon — a reminder of where we work and why it matters.
The H-1 Freeway
Oʻahu’s main artery connects communities from Kahala to Kapolei, and it is the road our team travels every single day. We know every on-ramp, every merge, and every detour. When you call us from anywhere on the island, we already know how to get to you.
Oʻahu’s Diverse Neighborhoods
From beachfront mansions in Kahala to Hawaiian homesteads in Nanakuli, from military housing in Pearl City to townhomes in Mililani, every community on this island has its own character. We have worked in all of them, and we bring the same respect and professionalism to each one.
The Koʻolau and Waiʻanae Ranges
The dramatic mountain ridgelines that frame Oʻahu’s geography are a constant backdrop to the work we do. The Koʻolau towers over the windward side; the Waiʻanae range defines the west. They are a reminder that this island is something extraordinary.
Pearl Harbor
The historic bay at the center of the island gives the surrounding communities — Pearl City, Aiea, Halawa, Waipahu — their identity and their sense of place. We have served homeowners in these communities for years, and the history of this area is never far from mind.
We are proud to serve every corner of this island. If you are an O'ahu homeowner who needs a plumber you can trust, we hope you will give us a call.
What Customers Say
Trusted by O'ahu Homeowners
“We called Alpha Omega after a pipe burst in our garage on a Sunday morning. They picked up immediately, gave us a clear ETA, and had a plumber at our house within the hour. Professional, fast, and the price was exactly what they said on the phone. We will not use anyone else on the island.”
