What the AI looks for in Water Heater Replacement Parts

Heating element match
Match voltage, wattage and mounting type (screw-in or flange) to the rating plate. Never energize an element until the tank is full. Wrong wattage can overload the circuit, and dry-firing burns out a new element within seconds.
Anode rod type
Magnesium suits most water. Aluminum/zinc helps with sulfur smell. Use a segmented or flexible rod when overhead clearance is short. The anode protects the tank from corrosion, so the right type extends tank life.
T&P relief valve rating
Match the pressure and temperature setting (commonly 150 psi / 210°F) and a BTU/hr rating at or above the heater's input. An under-rated relief valve is a safety hazard.
Gas control and thermocouple fit
Buy gas valves and pilot or flame-sensing parts listed for your heater's brand and model number. Gas controls are model-specific, and generic substitutes can fail to light or fail unsafely.
Thermostat position
Electric tanks use separate upper and lower thermostats; replace with the matching position and type. Upper and lower thermostats are wired differently and are not interchangeable.

Brands that matter

  • Camco: Widely stocked anode rods, elements and thermostats.
  • Rheem: OEM parts for Rheem and Ruud heaters.
  • A.O. Smith: OEM parts for A.O. Smith, State and American heaters.
  • Watts: Common T&P relief valves.
  • Resideo (Honeywell): Gas control valves used on many tank heaters.
  • Corro-Protec: Powered anode rods for persistent rotten-egg smell.

What to avoid

  • Universal gas control valves not listed for your heater model.
  • Raising element wattage beyond the heater label to get faster recovery.
  • Plugging or capping the T&P discharge line.

Questions

Is a rotten-egg smell a part failure?

It is usually bacteria reacting with a magnesium anode. Swapping to an aluminum/zinc or powered anode typically fixes it.
