This web site provides general information about water heaters. If you are experiencing water heater problems, please call an expert before it’s too late. No one wants to go without hot water or have a water heater tank leak water all over their floor.
Standard gas and electric water heaters use an insulated storage tank.
Water heaters are generally reliable but over time they can develop problems:
No hot water
Inadequate hot water
Rust colored water
Rotten egg odor
Low rumbling or popping noise
Higher pitched whining
Water leaking around base of heater
No Hot Water is Produced
Faulty gas pilot
Faulty gas thermocouple
Faulty gas pilot control valve
Faulty electric thermostat
Faulty upper electric heating element
Inadequate Hot Water
Unit is undersized for water heating demands
Broken or damaged dip tube allowing cold and hot water to mix in tank
Faulty plumbing installation has crossed cold and hot water connections
Gas supply or control problems
Faulty electric lower or upper heating element or high or low heating element thermostat.
A constant supply of lukewarm water during a shower is indicative of a defective upper heating element. Short duration hot water supply during a shower is indicative of a defective lower heating element.
Rust Colored Water
Corrosion occurring inside glass lined tank
Sacrificial anode rod is failing (anode rods dissolve slowly to prevent rusting in the tank)
Rotten Egg Smell
Bacteria in the tank sediment fed from hydrogen gas created from decay of sacrificial anode
Low Rumbling or Popping Noise
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.
Higher Pitched Whining (electric water heater)
Buildup of scale material on electrical heating elements
Water Leak Around Base of Water Heater
Faulty T&P (temperature and pressure) relief valve
T&P valve leak due to excessive pressure, overheating or stuck
