Frequently Asked Questions About Water Heater Repair in O'Fallon, MO
For a standard family of four, a 50-gallon tank is usually sufficient. If you have a larger family or a high-demand roman tub, you might need a 75-gallon tank or a high-capacity tankless water heater.
Hard water is very tough on tankless heaters because the intense heat causes calcium to rapidly build up inside the narrow heat exchanger. You must have your tankless unit descaled annually to prevent irreversible damage.
First, find the cold water valve above the heater and turn it clockwise to stop the water flow. Second, turn off the power (flip the breaker for electric, or turn the gas valve to 'off' for gas). Finally, call Water Heater Repair Tech at (877) 415-0636 for emergency service in O'Fallon, MO.
Tankless water heaters are an excellent upgrade if you want endless hot water and lower energy bills. They heat water only when you need it and take up much less space, making them a popular choice for homes in O'Fallon, MO.
Rusty hot water is a strong warning sign that the inside of your tank is beginning to corrode. If the anode rod is completely gone, the steel tank itself rusts. Call us immediately before the tank rusts through and floods.
