The emergence of Noise and The water smells rotten eggs

The emergence of Noise

Possible Causes

Noise heard is sound of boiling water. Excessive buildup of sediment in bottom of tank is causing overheating of tank bottom and boiling of water to occur.

Possible Repairs

Remove sediment by flushing water heater.

The water smells rotten eggs

Possible Causes

          Bacteria in the tank sediment fed from hydrogen gas created from decay of sacrificial anode.

Possible Repairs

• Flush water heater
• Using a hydrogen peroxide solution of 2 pints 3% peroxide to 40 gallons of water, treat tank and run some of the solution into water lines.
• Let peroxide solution set in tank and pipes for 2 hours. Solution is not toxic and requires no rinsing.
• If problem persists, replace anode with a zinc-alloy anode.
• If problem still remains, replace water heater with a plastic lined tank type.
