"Doug examined the water heater. Described the issue clearly. Recommended a replacement since a repair was next to impossible (leaking from bottom of water heater). Estimate given (if a replacement was needed, prior to work being done) was for all work and parts so nothing else was added on. Work was done in a few hours on the day of the call. Just great! Personable and friendly to interact with. Definitely would hire again if needed."

"Patrick and his crew did a great job for us. We had several plumbing issues and decided to replace all the water lines in our 60 year old forever home. In diagnosing a knocking sound Patrick discovered a builder defect and our gas line was compromised in several places. He and his crew replaced the water lines and gas line, replaced our 15 year old water heater that was failing and completed all the jobs on our repair list (replumb refrigerator, add pressure regulator to the main supply line). He did such a great job rebuilding the plumbing for the laundry area, basically rebuilding the wall, and I never thought it would look so good in my lifetime! They protected our floors and respected our property and wasted no time completing a large job. We have never seen any contractor clean up after a job as thoroughly as they did. Longo Plumbing is our plumber anytime we need one and you won't be sorry you hired them."

Water Heaters FAQs, answered by experts

In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.

Electric water heaters use a high amount of electricity, so they’re best for homeowners who subsidize their electric bill with solar or who live in an area with inexpensive electricity. For others, gas water heaters versus electric water heaters may be the more cost-effective solution, with the added bonus of heating water quickly and efficiently. No matter which you choose, you can lower your water temperature as low as possible to keep costs down.

Flushing biannually, checking the anode rod, and temperature settings maximize equipment lifespan while reducing surprise costs.

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions. 

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.
