Is your water heater starting to show its age? We get it—replacing it isn’t exactly something you’re excited about, but waiting too long can lead to some serious headaches. From cold showers to unexpected leaks and even flooding, a failing water heater can turn into a big hassle. The good news? Spotting the warning signs early can save you from those last-minute scrambles. Read on to better understand when it’s time for a replacement!

Water Heater Tank Is Leaking

A leaking water heater tank is a clear sign it’s time for a replacement. If you notice water dripping from the drain valve or pressure-relief valve, don’t panic—these types of leaks are usually minor. A plumber can typically fix them by repairing or replacing the faulty valve, which helps prevent damage to your floors or walls. However, if the tank itself is leaking, the situation is much more serious. This often means the tank has rusted through, and ignoring the problem could lead to a catastrophic rupture. Imagine gallons of water pouring out in just minutes—it’s not something you want to deal with. In fact, a ruptured water heater can release nearly a thousand gallons of water in an hour if the inlet valve isn’t shut off. If you spot a tank leak, the first step is to close the shut-off valve on the water heater's inlet pipe to stop the flow of water. Next, turn off the water heater to prevent further damage. If you can’t get a plumber to your home right away, a handy homeowner might consider draining the tank to minimize the risk of flooding. Just be sure to wait a few hours after shutting it off to let the water cool down and avoid burns. Taking these steps will keep the situation under control until a professional can help.

You Have a Gas Water Heater With a Pilot Light

Still using a gas water heater with a standing pilot light? It might be time to start thinking about an upgrade. Most modern gas water heaters have switched to electronic igniters, which are far more energy-efficient. Manufacturers moved away from pilot lights for a reason—they burn gas constantly, even when the water heater isn’t actively heating water. Replacing your unit could mean noticeable savings on your gas bill. Another important factor to consider is age. Gas water heaters with pilot lights were mostly phased out in the early 2010s. Since gas water heaters generally last around 8–12 years, chances are any unit with a pilot light is nearing the end of its lifespan. Upgrading now means you can avoid sudden breakdowns while enjoying the benefits of a newer, more efficient water heater.

You Have an Electric Water Heater That's 15+ Years Old

If your electric water heater is over 15 years old, it might be time to start planning for a replacement. Electric water heaters tend to last longer than gas models because they operate at lower temperatures, which reduces wear and tear. Even so, they usually don’t make it much past the 15-year mark. Waiting too long could leave you without hot water when you need it most. Replacing your water heater proactively has its perks. It gives you time to shop around, compare options, and choose a unit that fits your budget and specific needs. On the flip side, if you wait until it breaks, you might be stuck with an emergency replacement and fewer options. Avoid the hassle of cold showers and rushed decisions by staying ahead of the game—your future self will thank you!

Water Heater Needs Frequent Repairs

If your water heater keeps breaking down, it’s probably trying to tell you something: it’s time for a replacement. While it’s normal for certain parts, like the electric heating element or the anode rod, to wear out over time, repeated repairs are a red flag. When you’re constantly fixing one thing after another, those repair costs can quickly add up. At some point, replacing the water heater makes more sense than sinking money into a unit that’s nearing the end of its lifespan. A new water heater will not only save you from the hassle of constant breakdowns but also give you peace of mind knowing your hot water needs are covered reliably.

Hot Water Looks Brown or Rusty

Noticing rusty or brown-colored hot water? That’s a pretty clear sign your water heater’s tank might be rusting from the inside. While draining and flushing the tank can sometimes clear things up temporarily, it’s usually not a long-term fix. The rust will likely return, and no one enjoys showering in discolored water. The bigger issue isn’t just the appearance—it’s what the rust means for your water heater’s health. A heavily rusted tank is at serious risk of leaking or even rupturing, which can lead to major water damage. If you’re dealing with rusty water, the safest move is to schedule a replacement as soon as possible to avoid bigger headaches down the road.

Water No Longer Gets Sufficiently Hot

If your water isn’t getting as hot as it used to, it can be a frustrating problem—but it doesn’t always mean you need a new water heater. Sometimes, it’s as simple as a failed electric heating element or an issue with the gas burner. Tankless water heaters can also experience heating issues due to mineral deposits building up around the heat exchanger. The good news? Many of these problems are repairable, giving your water heater a few more years of reliable service. That said, whether a repair is worth it depends on the age and overall condition of your unit. An experienced plumber, like the pros at Benjamin Franklin Plumbing®, can inspect your water heater and help you decide if it’s better to repair or replace. Either way, you’ll get expert advice to keep your hot water flowing.

Key Factors to Consider When Selecting a New Water Heater

Choosing a new water heater can feel like a big decision, but it really comes down to what fits your home and lifestyle. The first choice is between a tank and a tankless unit. Tank water heaters cost less upfront but may end up costing more over time because they’re less energy-efficient and don’t last as long. On the other hand, a tankless water heater can lower your energy bills and provide unlimited hot water—but keep in mind that it can only heat so many gallons per minute, which might limit how many fixtures you can use at once. If you go with a tank water heater, size matters. A 30- to 40-gallon tank is typically enough for two people, while households with four or more will usually need a 60- to 80-gallon tank. For a tankless water heater, you’ll need to focus on flow rates, which determine how many gallons of water the unit can heat per minute. Since calculating flow rates can be tricky, it’s a great idea to consult an experienced plumber who can recommend the best size and model for your home.
