When a tank water heater stops working in a Durham home, the symptom tells you where to look. No hot water points to a failed heating element or thermocouple. Leaking points to a valve, fitting, or failed tank lining. Rumbling points to sediment. Drain Express diagnoses first, repairs same-day in most cases, and carries common parts on the truck for Durham and Chapel Hill calls.
Common Symptoms and Repairs
No Hot Water
Electric unit: failed heating element or thermostat. Gas unit: failed thermocouple, pilot that will not stay lit, or faulty gas valve. Both are same-day repairs on units under 12 years old in reasonable condition.
Leaking
Leak from T&P valve, inlet/outlet connections, or drain valve is repairable. Leak from the tank body means the glass lining has failed and the unit is not worth repairing. We tell you which situation you have before recommending anything.
Noise: Rumbling or Popping
Almost always sediment. Wake County and Orange County water carries dissolved minerals that accumulate at the tank bottom and force the element to heat through insulating scale. A sediment flush resolves this in most cases.
Repair vs Replace
Under 8 years with a repairable failure: repair. Over 12 years with a tank body leak or major corrosion: replace. Ages 8 to 12: we weigh repair cost against replacement cost and remaining efficiency. We give you both numbers before recommending a direction.
What We Carry on the Truck
Heating elements, thermostats, thermocouples and thermopiles, T&P relief valves, dip tubes, anode rods, and inlet/outlet fittings. Most single-component failures are fixed in one visit.
