Common Questions About Water Heater Repair in Old Brookville, NY

A sulfur odor is usually the result of harmless sulfur bacteria reacting with the tank's magnesium anode rod. Our technicians in Old Brookville, NY can disinfect the tank and install an aluminum-zinc or powered titanium anode rod to permanently eliminate the odor.
We service and repair all major manufacturers, including Rheem, Bradford White, A.O. Smith, Rinnai, Navien, State, Lochinvar, Bosch, and Whirlpool. Our service trucks are stocked with OEM parts for both storage tank and tankless systems. Contact us at (877) 652-1357.
If your water heater is under 10 years old and the problem involves a replaceable component—such as an electrical element, thermostat, gas valve, or thermocouple—a repair is usually the most cost-effective route. If the internal storage tank is corroded and leaking from the bottom, a replacement is necessary.
A tripping breaker usually indicates a cracked or shorted heating element inside the tank, or a malfunctioning high-limit reset switch on the upper thermostat. Our technicians can test element resistance and replace burnt components quickly.
Water dripping from the T&P valve typically indicates excessive pressure in your plumbing system, thermal expansion issues, or a worn-out valve spring. We can test your water pressure and install an expansion tank or new safety valve as needed.
