Frequently Asked Questions About Water Heater Installation in Arnold, MO

A healthy gas flame should burn a crisp, clean blue. A lazy yellow flame indicates incomplete combustion, dirty burner air shutters, or carbon monoxide hazard. Have Expert Water Heater Pros inspect the burner assembly immediately.
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 Arnold, MO can sanitize the tank and install an aluminum-zinc or powered titanium anode rod to neutralize the smell permanently.
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.
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.
Yes! Installing a dedicated recirculating pump or a thermal bypass valve system keeps hot water constantly moving through your pipes, delivering instant hot water to your furthest shower and saving thousands of gallons of wasted water.
