How to fix a smelly water condition caused by your Superior gas water heater

Certain water conditions cause a reaction between the anode rod and supply water, which results in hydrogen sulfide gas being dissolved in the tank water.

The anode rod protects the tank from corrosion. A chemical reaction between the supply water and the anode rod can produce hydrogen sulfide gas and cause the hot water to smell like rotten eggs in some conditions. Replace the anode rod with a less-reactive zinc-aluminum anode rod to combat the rotten-egg smell.

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

• Check the thermostat setting. The typical water heater 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.
