Some point in time, you'll encounter some issues in your gas or electric water heater tanks. Common problems include insufficient or no hot water, rusty or smelly water, strange noises and leakages.
When water that comes out from your shower is unpleasantly cold, the culprit is likely your water heater. You probably need to check the pilot, thermocouple and gas control valve when you have a gas water heater. If you have an electric unit, check the thermostat and the heating elements. If you think there's something wrong with any of these components, have a professional hot water technician check and fix your unit.
When your water heater delivers some hot water but not sufficient to your needs, it is probably the temperature setting or the heating components of your electric heater, any tank deposits or a disconnected dip tube.
Accumulation of bacteria and pipe corrosion likely cause discolored water and rotten egg stench that comes out when you switch on the faucet.
Accumulation of sediments that settle at the bottom of the tank could cause the tank to overheat, as a result the water boils. This causes the rumbling noise from your water heater. Flushing your water heater will remove the deposits.
Meanwhile, the hissing sound would indicate a tank leak that lets water go down onto the burner.
If your water heater has been idle for a while then recently turned back on, condensation might be happening from the bottom of the tank leaking onto the burner. The hissing noise will diminish once the tank is fully heated.
A faulty T&P relief valve or a plumbing connection leakage, or even the tank itself could be the cause of a leaky water heater. T&P valve and plumbing leaks can be fixed but when the leak is in the water hank, it should be replaced right away.
