Tank Water Heater Atherton: Problems-Possible Causes & Possible Repairs

Turn off power to an electric Tank Water Heater Atherton. Do this by turning off the circuit breaker or fuse powering the heater. Turn gas pilot control valve to "pilot" setting. Shut off water supply to water heater.

Atherton Tank Water Heater is generally very reliable but occasionally they do have problems. These problems can include:

1. Rotten Egg Smell 2. Water Leak around Base of Heater 3. Higher pitched whining (electric water heater) 4. Low Rumbling or Popping Noise 5. Rust Colored Water 6. No Hot Water is produced

1. Rotten Egg Smell Possible Causes: Bacteria in the tank sediment fed from hydrogen gas created from decay of sacrificial anode. Possible Repairs • Flush Atherton Tank 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 Tank Water Heater Atherton with a plastic lined tank type.

2. Water Leak around Base of Tank Water Heater Atherton Possible Causes • Faulty T&P (temperature and pressure) relief valve • T&P valve leak due to excessive pressure, overheating or stuck • Leak from overhead or nearby plumbing connection • Leaking water tank (corrosion likely)

Possible Repairs • Place bucket under overflow pipe. Open and flush T&P valve clear of debris. If leak remains from valve, replace valve. • Reduce thermostat setting to prevent tank overheating and opening T&P relief valve. • Inspect bottom of tank by looking through combustion chamber. If water marks or heavy rusting is noticed or if water is noticed setting in combustion chamber bottom, and then the water heater needs to be replaced.

3. Higher pitched whining (electric Tank Water Heater Atherton) Possible Causes • Buildup of scale material on electrical heating elements Possible Repairs • Flush water heater. • Clean scale from Atherton Tank Water Heater tank and elements • Install low-watt density heating elements which have larger surface areas transferring heat to water more efficiently, conducting less electrical wattage per square inch than a standard high-wattage element.

4. Low Rumbling or Popping 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 Tank Water Heater Atherton.

5. Rust Colored Water Possible Causes • Corrosion occurring inside glass lined tank • Sacrificial anode rod is failing (anode rods dissolve slowly to prevent rusting in the tank) Possible Repairs • Replace sacrificial anode rod with magnesium anode rod. Anode rods are available from a plumbing supply house.

6. No Hot Water is produced Possible Causes • Faulty gas pilot • Faulty gas thermocouple • Faulty gas pilot control valve • Faulty electric thermostat • Faulty upper electric heating element Possible Repairs • Check gas pilot flame and pilot operation. See How to Light a Gas Furnace Pilot for similar operation. • Re-tighten, reposition or replace the gas thermocouple. • Replace the gas pilot control valve. • Confirm power is being provided to the electric water heater thermostat. • If power is being provided to electric thermostat, replace thermostat or heating element.
