Frequently Asked Questions About Water Heater Repair in Keystone, SD
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, Water Heater Repair Masters services commercial water heaters for restaurants, laundromats, hotels, healthcare clinics, and apartment complexes throughout Keystone, SD. We understand commercial downtime and offer high-priority dispatch.
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 Keystone, SD can sanitize the tank and install an aluminum-zinc or powered titanium anode rod to neutralize the smell permanently.
A pilot light that won't stay lit is usually caused by a faulty or carbon-coated thermocouple, a blocked pilot orifice, a defective gas valve magnet, or poor combustion air intake. Call (877) 276-9926 to have a technician test and replace the thermocouple safely.
When water heats up, it expands by about 2% to 3%. In homes with a backflow preventer or check valve, this expansion creates severe pressure spikes. A thermal expansion tank absorbs this pressure, preventing leaks and protecting your warranty.
