Water heaters rarely fail without some warning. Most give signs for weeks or months before they stop producing hot water, or start leaking. Understanding those warning signs can help you decide whether it’s time for a repair, replacement, or simply a professional inspection.
How Long Does a Water Heater Last?
One of the most common questions we hear is, “How long should my water heater last?”
The honest answer is: it depends.
Most standard tank water heaters come with a 6-year manufacturer’s warranty, but that doesn’t mean you should expect to replace it in six years. At the same time, it doesn’t guarantee it will last much longer either.
Years ago, it wasn’t unusual for us to replace water heaters that had been in service for 20 years or more. Unfortunately, that’s becoming increasingly rare. Today, we typically see tank water heaters last around 8 to 10 years, though some may last longer depending on water quality, maintenance, and how heavily they’re used.
Here in Columbus, hard water can also play a role. Mineral buildup inside the tank can make your water heater work harder over time and may shorten its lifespan. If your home has hard water, installing a water softener can help reduce that buildup and protect not only your water heater but many other plumbing fixtures as well. (Link to your water softener article.)
If your water heater is approaching the 8- to 10-year mark, it doesn’t necessarily mean it needs to be replaced. However, it’s a good time to start paying closer attention to signs like leaks, rust-colored water, unusual noises, or inconsistent hot water, topics we’ll cover below.

Repair or Replace?
Not every water heater problem means you need a new water heater. In many cases, replacing a thermostat, heating element, gas control valve, or another component can get your hot water back up and running without replacing the entire unit.
So how do you decide?
One of the biggest factors we consider is the age of the water heater. If it’s only a few years old and needs a repair, fixing it often makes good financial sense. In fact, if your water heater is less than six years old, many replacement parts may still be covered under the manufacturer’s warranty. While you’ll typically still be responsible for the labor to install those parts, the warranty can significantly reduce the overall repair cost.
However, if your water heater is approaching or beyond the 8- to 10-year mark, investing several hundred dollars in repairs may not be the best long-term decision, especially if you’re also noticing some of the warning signs listed above.
Another important factor is the type of problem. If the water heater tank itself is leaking, unfortunately there isn’t a repair that will stop it. Once the tank has failed, replacement is the only option.
For repairs involving replaceable parts, the decision isn’t always as straightforward. We consider the age of the unit, the cost of the repair, its overall condition, and what you’re likely to get out of it before making a recommendation.
At Lohmeyer Plumbing, our goal isn’t simply to sell you a new water heater. It’s to help you make the decision that makes the most sense for your home and your budget. If we believe a repair is the better option, we’ll tell you. If we think you’re likely to spend money repairing a water heater that’s nearing the end of its life, we’ll explain why a replacement may be the wiser investment.
What to Expect When Replacing Your Water Heater
Replacing a water heater is one of the most common services we perform, and our goal is to make the process as smooth and stress-free as possible.
When you call our office, we’ll ask a few questions about your existing water heater, including its capacity, whether it’s gas, electric, or power vent, and where it’s located in your home. This helps us make sure we arrive with the correct replacement water heater and determine whether the job requires one technician or two. For example, water heaters located in basements, elevated on stands in garages, or installed in tight spaces are often safer and more efficient to replace with two technicians.
In most cases, we can provide an upfront price over the phone before scheduling your appointment, so you’ll know what to expect before we arrive.
Most water heater replacement appointments take about 2 to 3 hours from start to finish. During that time, your hot water will be unavailable, and if your existing water heater doesn’t have its own shutoff valve, the water to your entire home may need to be turned off for part of the installation.
Once your new water heater is installed, it typically takes 30 to 45 minutes for the tank to heat the water before you’ll have hot water available again.
When the job is complete, we’ll haul away and properly dispose of your old water heater, so you won’t have to worry about it.
All of the standard tank residential water heaters we install include a 6-year manufacturer’s warranty on the tank and parts, giving you added peace of mind.
Not sure what size or type of water heater you have? Don’t worry. Our office staff can usually help you identify it over the phone, or you can text us a few photos of your existing water heater. We’ll do our best to identify the information we need so we can provide an accurate quote and arrive prepared for your installation.
