Water Heater Problems We Repair in Rocky Mount

Most water heater calls come down to a short list of faults, and most of them are repairable in one visit with the parts on the truck. Here is what we see, and what is usually behind it:

• No hot water at all. On an electric tank, a tripped high-limit switch, a failed heating element or a bad thermostat. On a gas tank, a thermocouple that no longer holds the pilot, a pilot that has gone out, or a failed gas control valve.
• Not enough hot water, or it runs out early. Sediment taking up space in the bottom of the tank, one dead element on a two-element electric unit, or a broken dip tube letting cold water mix at the top.
• Rumbling, popping or banging. Sediment on the tank bottom trapping water that boils and bangs against it. A flush clears it if the tank is not too far gone.
• Leaking from the top. Usually the inlet and outlet fittings or the temperature-and-pressure (T&P) relief valve, both repairable. An expansion tank that has failed can also push the T&P valve to discharge.
• Leaking from the tank body. A corroded tank. This one is not a repair; see the replacement section below.
• Discolored or smelly hot water. A spent anode rod, the sacrificial part that keeps the tank from rusting. Replacing it is a routine repair that extends the tank's life.
• Pilot keeps going out. A weak thermocouple, a dirty pilot assembly, or a draft problem at the burner.
• Tankless error codes and the cold-water sandwich. Scale on the heat exchanger, a flow sensor reading low, or an ignition fault. Error-code diagnosis and descaling are the usual fixes.

Tank vs. Tankless Repair

Tank water heaters, including the Rheem and A.O. Smith units we install, are repaired on the spot for most faults. Heating elements, thermostats, thermocouples, gas control valves, T&P relief valves and anode rods are stocked on the truck, and a sediment flush is done at the same visit. Tankless units from Rheem and Noritz fail differently: the common problems are scale buildup on the heat exchanger, flow sensors that no longer read correctly, and ignition or venting faults, and the unit reports most of them as an error code on the display. We read the code, confirm the cause, and either descale the unit or replace the failed component. For the full picture on tankless-specific work, see our tankless water heater repair page. Both types are covered under our plumbing services, and the annual water heater check is part of the plumbing side of our maintenance plan.
