Frequently Asked Questions About Water Heater Repair in Bismarck, MO

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.
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.
No, a leaking Temperature and Pressure (T&P) valve means there is either excessive pressure inside the tank, the temperature is dangerously high, or the valve itself has failed. This is a safety issue that should be addressed immediately.
Yes! When you hire Water Heater Repair Tech for a water heater replacement in Bismarck, MO, we handle the draining, disconnection, haul-away, and proper recycling of your old tank at no extra hassle to you.
A puddle could mean a leaking drain valve, a leaking pressure relief valve, condensation, or a rusted-through tank. Dry the area and see where the drip is originating. If it's coming from the bottom of the tank itself, you need a replacement.
What Homeowners Say About Our Hot Water Service in Bismarck
"Most honest plumbers in Missouri! Another company told me my tank was dead and quoted me $3,000 for a new one. Water Heater Repair Tech came out, found a burnt wire connection, and fixed it for under $200. Customers for life."
"Our Navien tankless water heater kept shutting off randomly. The expert from Water Heater Repair Tech knew exactly what to look for, cleaned the dirty flame sensor, and tested the gas pressure. Fantastic troubleshooting skills!"
"I called Water Heater Repair Tech for a second opinion on a repair. Their technician proved that my gas valve was fine and just replaced the $30 thermocouple. My water heater has been working perfectly ever since."
