Common Commercial Water Heater Repairs


Commercial water heaters are essential for businesses, providing the hot water needed for various operations for tenants, employees, and customers. Malfunctioning water heaters can disrupt businesses and lead to costly downtime. Understanding common commercial water heater repair in Branchburg can help commercial property owners know when to call for professional help on commercial equipment and prevent significant issues. Let’s go over some common water heater repairs you’re likely to experience as a commercial property owner.

Signs Your Commercial Water Heater Needs Repair

  • Inconsistent Water Temperature: Fluctuating temperatures often indicate a malfunctioning thermostat or a failing heating element. This inconsistency can disrupt business operations.
  • Unusual Noises: Banging, popping, or hissing sounds usually result from sediment buildup or a failing heating element, indicating that the heater is working harder than necessary.
  • Discolored or Rusty Water: Discolored or rusty water signals corrosion inside the water heater tank, which can lead to leaks and ultimately tank failure.
  • Leaks or Pooling Water: Visible water around the base of the heater indicates problems such as a faulty pressure relief valve, loose connections, or a corroded tank.
  • Decreased Water Pressure: A sudden drop in water pressure suggests sediment buildup in the tank or issues with the water supply lines, affecting operational efficiency.

  • Thermostat Issues: A faulty thermostat causes inconsistent water temperatures. Diagnosing involves checking temperature settings and testing the power running to the thermostat. 
  • Sediment Buildup: Sediment buildup is common, especially in areas with hard water. We can flush the tank periodically to remove sediment, maintaining efficiency and longevity.
  • Pilot Light Problems: A pilot light can go out due to a faulty thermocouple, drafts, or a clogged orifice. 
  • Faulty Heating Elements: Inconsistent temperatures in electric water heaters may result from failing heating elements. 
  • Leaks and Drips: Leaks often stem from issues with valves, connections, or the tank. At the first sign of leaks, it’s important to call us for a prompt repair to prevent the leak from getting worse and causing major water damage.
