Signs Your Water Heater Needs Repair

Water heaters often give off subtle signs before they fail completely. Addressing issues early can prevent larger problems and extend the life of your unit. If you’re noticing any of the following, it’s time to call in a professional:

No hot water or water that doesn’t get hot enough
Fluctuating water temperatures
Water with rust or discoloration
Strange noises—like popping, rumbling, or hissing
Leaks or puddles around the unit
Unusual smells from hot water taps

Our Miami-based technicians will inspect your unit, identify the problem, and explain the issue in straightforward terms. If repairs are possible, we’ll get it done right away using quality replacement parts that match your water heater’s model and manufacturer specifications.

Common Water Heater Repairs We Handle

Most water heater issues can be fixed without replacing the entire unit—saving you money and avoiding unnecessary upgrades. Our team is equipped to repair both electric and gas-powered water heaters, as well as traditional tank and tankless models.

We frequently repair:

Heating elements and thermostats
Pressure relief valves
Thermocouples and pilot light assemblies
Gas control valves and igniters
Leaky drain valves or inlet/outlet fittings
Expansion tanks and anode rods

We carry parts for leading brands like Rheem, AO Smith, Bradford White, Navien, Rinnai, and more. Whether your unit is a few years old or nearing the end of its life, we’ll offer repair options that get you back up and running as soon as possible.

Tank vs. Tankless Water Heater Repairs

Tank and tankless water heaters require different repair techniques. Our plumbers are trained in both technologies and will tailor the fix to the system you have.

Tank water heaters: These systems may develop issues with sediment buildup, corrosion, or faulty thermostats. We flush tanks, replace worn parts, and address leaks without replacing the whole unit.

Tankless water heaters: More complex, but highly efficient. We repair sensors, flow regulators, gas valves, and heat exchangers. We also descale units to restore performance when mineral deposits slow down heating.

No matter the system, we provide a clear diagnosis and honest recommendation—repair when it makes sense, replace when it’s more cost-effective.

Our trucks are stocked with the most common repair parts, so we can often fix your heater on the spot. If replacement is required, we’ll help you choose the right unit and install it quickly to restore service with minimal disruption.

Water Heater Leaks

Leaks are a major warning sign and can lead to serious water damage if not handled quickly. We inspect your system to determine whether the leak is coming from a valve, fitting, or the tank itself. Minor leaks can often be repaired, but if the tank is cracked or rusted through, replacement may be the only safe option.

Flushing and Maintenance to Prevent Repairs

Many water heater failures are caused by sediment buildup inside the tank. We offer routine flushing and maintenance to remove these deposits and improve your heater’s efficiency. Annual maintenance extends the life of your water heater and helps prevent unexpected repairs or replacements.

Is It Time to Replace Instead of Repair?

Some water heaters reach the end of their lifespan—especially if they’re over 10 years old and experiencing repeated problems. In these cases, we’ll walk you through the replacement process and help you decide between a similar tank model or an upgraded tankless option. We never push replacements unless it’s truly the best long-term option for your home or business.
