Magnet Plumbing removes your old water heater in Hanover, NH 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 Hanover 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.

Replace your water heater in Hanover 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.
Extend the life of your new water heater in Hanover by flushing the tank annually to remove sediment, replacing the anode rod every 3 to 5 years, setting the thermostat to 120°F to reduce mineral buildup and tank stress, and inspecting the T&P valve annually. Magnet Plumbing offers annual water heater maintenance service in Hanover to keep your unit running efficiently.
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 Hanover 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 Hanover jurisdictions in NH require a permit for water heater replacement to ensure the installation is inspected for code compliance. Magnet Plumbing handles the permit process for Hanover water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.
Our reputation is built on results. Here is what our customers have to say.
"Magnet Plumbing fixed a leaky kitchen faucet and installed a new toilet in the master bath on the same visit. They were in and out in a few hours and cleaned up everything before they left. Will absolutely use them again."
"Highly recommend!! Best plumber ever! Very professional, super nice, quick response and excellent quality of work at fair value prices."
"Smelled gas in the basement late at night and called the emergency line. A plumber was dispatched within the hour, located the leak at a corroded fitting on the water heater gas line, and repaired it on the spot. They even came back the next day to re-verify with the gas detector. Truly appreciated the care taken."
