Tankless Water Heater Repair in Marietta, GA

Tankless water heater repair across Marietta

A tankless unit is endless hot water until it stops. Then it is a wall-mounted box flashing a fault code while the family waits for showers. Cobb County water is on the mild side, but scale still piles up inside the heat exchanger and most units here need a flush every 12 to 18 months. We work on every major brand sold in metro Atlanta.

Why descaling matters in Marietta

Cobb County tap water averages 3 to 5 grains per gallon. Mild on paper, real enough inside a copper heat exchanger. Restaurants near the Marietta Square or the Battery Atlanta typically need a 6 month flush because of run-time. Most homes do fine with a yearly cycle. Skip it for two or three years and the unit starts throwing scale codes and the warranty stops covering you.
