Water Heater Repair and Installation on Oahu
Your water heater keeps showers hot and runs the dishwasher and washing machine. Heavy or frequent use means that one day you may be looking at water heater repair or replacement. When that day comes, you’ll have a trusted, licensed plumber to call.
How we help with water heaters
Temperature problems
Not satisfied with your shower or bath temperature, or hot water runs out too soon? If your water heater can’t keep up, we investigate and figure out why.
Water heater repair
Thermostats, valves, leaks and connections: we find the fault, explain it, and give you clear pricing before work begins.
Replacement & new installation
When it’s time to replace, we help you choose a new water heater that can handle the demands of your household, then install it.
Maintenance & upkeep
We can suggest a maintenance schedule that keeps your water heater working well, and regular checks can spot problems before they interrupt your day.
Leaks at the heater
Water around the tank or corroding supply pipes? We stop the leak and replace damaged pipe. See leak detection and repair.
Commercial water heating
Water heating and mechanical equipment installation for commercial buildings. See commercial plumbing.
Repair or replace?
Not every water heater problem means a new unit. Sometimes it’s a thermostat, a valve or a connection. Other times the tank or its supply pipes are corroded and replacement is the better spend.
Whichever it is, we’ll explain the issue, walk through your options, and provide clear pricing before work begins. If replacement makes sense, we’ll help you pick a water heater sized for your household rather than upselling you something you don’t need.
Water heaters are one part of what we do for Oahu homes; see residential plumbing and all our plumbing services, or request service online.

Water heater questions
Do you repair water heaters or only replace them?
Both. We repair water heaters, including temperature problems and thermostats, and we replace and install new units when repair no longer makes sense.
How do I know if I need a new water heater?
If the water isn’t getting hot enough, runs out too quickly, or the tank or its pipes are leaking or corroded, call us. We’ll investigate, explain what we find, and give you clear pricing for repair or replacement before any work begins.
Can you help me choose between a tank and a tankless water heater?
Yes. When you’re replacing a water heater, we can help you choose the best new water heater for the demands of your household. Call us or request service online and tell us what you have now.
