Magnet Plumbing removes your old water heater in Halawa, HI carefully — draining the tank, disconnecting all utilities safely, and hauling the unit away. We inspect the installation area for any issues that should be addressed before the new unit is installed.
Our licensed Halawa plumber installs the new water heater with all code-required components — proper supply line connections, gas or electrical hookup, T&P valve and drain tube, expansion tank if required by local code, and correct venting.
We fill the tank, start the unit, check for leaks at all connections, and verify the water reaches the correct temperature. We walk you through the controls and any maintenance the manufacturer recommends.
Answers to frequently asked water heater replacement questions from Halawa homeowners.
Replace your water heater in Halawa when it is over 10 to 12 years old, produces rusty or discolored water indicating internal corrosion, leaks from the tank body, requires frequent repairs, or no longer meets your household hot water demand. A water heater approaching these conditions often fails unexpectedly — replacement before failure avoids an emergency.
For a tank water heater, the right size depends on the number of occupants: 30 to 40 gallons for 1 to 2 people, 40 to 50 gallons for 3 to 4 people, and 50 to 80 gallons for larger households. For tankless units, the required flow rate in GPM determines the correct unit size. Magnet Plumbing assesses your household demand and recommends the right unit for your Halawa home.
Tank water heaters cost less upfront and are simpler to install. Tankless units provide endless hot water on demand and typically have lower operating costs, but cost more initially. For most Halawa families, a quality tank unit in the correct size is the most cost-effective choice. Our plumbers help you compare the total cost of ownership for your specific situation.
Most Halawa jurisdictions in HI require a permit for water heater replacement to ensure the installation is inspected for code compliance. Magnet Plumbing handles the permit process for Halawa water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.

"Our older boiler was making banging noises and losing pressure. The technician diagnosed a failed expansion tank, replaced it, and the system has been silent ever since. Reasonable rate and quick turnaround."
