Top repair parts for Reliance gas water heaters

Gas valve assembly. The gas valve assembly monitors tank water temperature and cycles the burner on and off to maintain set water temperature.

Anode rod. The anode rod protects the tank from corrosion. Replace the anode rod if it wears out or replace the anode rod with a less-reactive zinc-aluminum anode rod to combat a rotten-egg smell coming from hot tap water.

High temperature cut-off switch. The high temperature cut-off switch shuts off the water heater if water temperature gets too hot. Replace the high temperature cut-off switch it it's defective.

Flammable vapor sensor. The flammable vapor sensor shuts off the gas supply to the water heater if it detects flammable vapors. A service technician needs to investigate the cause of a flammable vapor sensor trip before the water heater can be put back into service. The service technician will replace the flammable vapor sensor if it isn't working properly.

What to do when you're not getting enough hot water from your Reliance gas water heater

• Check the thermostat setting. The typical thermostat temperature setting is 120 degrees. Raise the thermostat setting slightly if it's set below 120 degrees.
• Drain and flush tank sediment. Tank sediment interferes with water heating so drain and flush the tank to remove sediment.
• Check the gas supply. Make sure that the gas supply cut-off valve is fully open and that you have an adequate gas supply provided to the water heater.
• Check water heater tank size to see whether it's adequate for your hot water usage needs. You'll keep running out of hot water if the water heater is too small for your needs.
• Check piping insulation. Repair any damaged insulation and install new insulation if needed to keep water hot as it travels through pipes.
