Frequently Asked Questions About Water Heater Repair in Lannon, WI

A typical family of 4 to 5 requires a 50-gallon gas water heater or a 55 to 80-gallon electric tank (or a tankless unit producing 7.5 to 9.5 gallons per minute) to ensure sufficient first-hour hot water capacity.
We service all leading manufacturers including Rheem, Bradford White, A.O. Smith, Rinnai, Navien, State, Lochinvar, Bosch, and Kenmore. Our field vehicles carry factory OEM parts for both storage tanks and tankless systems. Contact us at (877) 276-9926.
A sulfur odor is usually caused by anaerobic bacteria in your water supply reacting with the tank's magnesium sacrificial anode rod. Our technicians in Lannon, WI can sanitize the tank and install an aluminum-zinc or powered titanium anode rod to neutralize the smell permanently.
If your water heater is under 10 years old and the problem involves a replaceable component—such as a heating element, thermostat, thermocouple, or relief valve—repair is usually cost-effective. However, if the internal tank has rusted through and is leaking from the base, replacement is necessary.
The anode rod is a magnesium or aluminum core inside the tank that attracts corrosive minerals, sacrificing itself to prevent the steel tank from rusting. It should be inspected every 2 to 3 years and replaced when more than 50% depleted.
