Repair vs. Replacing a Hot Water Heater

Water Heater Repair or Replace?

Water Heater Repair or Replace? What Every Homeowner Should Know

Most homeowners don’t think about their water heater until there’s a problem. Suddenly, that nice hot shower turns ice-cold, or you notice a puddle of water forming around the unit. Now what? You may be stuck wondering if you should either repair your water heater or just replace it entirely. Understanding the signs of trouble and knowing when to invest in a new unit can help you avoid unexpected breakdowns and keep your home running smoothly.

Let’s break down the signs.

Signs your water heater needs a repair

Not every issue means your water heater is on its last leg. Some problems can be fixed with a simple water heater repair, saving you money and extending the life of your unit. Here are some common signs that your water heater may just need a little TLC:

• Water isn’t staying hot long enough - If your showers are getting colder faster than they used to, the culprit could be a failing heating element or a faulty thermostat. Over time, these components can wear out, making it difficult for the heater to maintain a consistent temperature. The good news? Both can typically be replaced without needing to invest in a new unit.
• Rumbling or popping noises - Are you hearing strange sounds from your water heater? That popping or rumbling noise is often due to sediment buildup at the bottom of the tank. Over time, minerals from your water settle and harden, causing the burner or heating element to overheat. Flushing the tank can resolve the issue, which should be done once a year to keep your heater running efficiently.
• Rust-colored water - If you notice discolored or rusty water, your water heater could have corrosion inside the tank. However, before assuming the worst, check whether the issue is with your plumbing.
• A small leak - A loose connection or faulty valve can sometimes be repaired without replacing the entire unit. However, not all leaks mean you need a new water heater. Sometimes, it’s just a loose connection, worn-out drain valve, or a faulty temperature and pressure relief (T&P) valve. If caught early, these issues can be repaired quickly and affordably.

Signs your water heater needs replaced

While repairs can sometimes extend the life of your water heater, there comes a point when water heater replacement is the smarter (and more cost-effective) decision. Here’s when you should seriously consider upgrading your unit:

• The unit is over 10 years old - Most traditional tank-style water heaters last between 8 and 12 years, depending on usage and maintenance. If your unit is approaching or surpassing the 10-year mark, it’s likely becoming less efficient and more prone to failure. Replacing it proactively can save you from an emergency breakdown, even if it's still working.
• Major leaks - A small leak from a connection or valve might be repairable, but if the tank leaks, that’s a major red flag. Water heaters corrode from the inside over time, and once the tank fails, there’s no repairing it. Ignoring the leak can lead to severe water damage, mold growth, and even structural issues in your home.
• Frequent repairs - Have you called for multiple water heater repairs in the past year? Your unit may be on its last leg if you constantly deal with lukewarm water, leaks, or strange noises. The cost of continuous repairs can quickly add up, often approaching the price of a new unit. Instead of repeatedly fixing an aging system, investing in a new, energy-efficient model can save you money in the long run.
• Energy costs keep increasing - Older water heaters lose efficiency over time, requiring more gas or electricity to heat the same amount of water. If you’ve noticed a steady increase in utility bills, your water heater might be the culprit.

How to extend the life of your water heater

Regular maintenance on your water heater can help extend its lifespan while keeping it running efficiently. Flushing the tank periodically helps remove sediment buildup that can reduce performance and lead to costly repairs. Checking the anode rod for corrosion and making sure all components are functioning correctly can also prevent unexpected breakdowns. If you’re unsure about maintenance, our plumbing experts can inspect, flush, and service your water heater to ensure it’s operating at peak efficiency.

Why an aging water heater is a bigger problem than you think

An aging or failing water heater doesn’t just lead to cold showers. Even a tiny leak can cause significant water damage over time, leading to mold growth, weakened flooring, and potential structural problems. Additionally, as sediment builds up inside the tank, it can clog pipes and restrict water flow, reducing water pressure and uneven heating throughout your home. Older water heaters are also less energy-efficient, requiring more power to heat water and ultimately driving up your monthly utility bills.
