Common Water Heater Problems and Fixes

Water is Leaking

Water leaks are normally caused by loose valves and plumbing joints, but they can also be tank problems. Leaking water can cause damage to your home, so it is necessary to repair the leaks early.
Leaks of water heater tanks can be due to loose heating elements or due to tank corrosion. Examine the elements of the water heater and, if required, tight them. A corroded unit cannot be repaired and needs to be replaced. Turn off the power and water supply, then drain water from the tank completely and replace the tank to stop the leaking.

No Hot Water

It is very irritating when you turn on the hot water tap and you only get room temperature water. The common cause for no hot water is that the circuit breaker has tripped and you should first check the breaker box.
If repairing the breaker doesn’t work, the problem might be in some other part, that needs to be repaired, such as the heating element. If the heating elements are not working then they need to be replaced.
It may also be a problem with the reset switch on the thermostat. It may have tripped due to very hot water or just broken and needs replacement.
If your water heater is at least 10 years old and you’re not getting hot water, it’s maybe time to replace it.

Water Heater is Making Noise

It’s common to hear steam-like sounds getting from your water heater as it boils water. But if you hear popping, banging, knocking, and hissing sounds or some other strange noise coming from the water heater, then it is not normal.
Usually, these sounds are caused by a buildup of residue. Solids usually grow up on either the heating element or on the bottom of the water tank.
Residue buildup is normal if you are living in an urban area with high mineral content in the water. If this is the problem, you may need to call a plumber and clean out the tank.

Rusty and Smelly Water

Rusty hot water is usually a sign of corrosion of the anode rod or even water tank itself. If not treated on time, your water heater will need replacing once the corrosion gets severe enough for the tank to develop a leak. Repairing the anode rod is easy to do and can continue years to your water heater.
If the water is not discolored but it is dirty or smelly, it may be because of scale build-up on the heating elements or sediment in the tank that’s making its way into the hot water faucet.

Too Much Hot Water

This is likely related to the thermostat where the temperature is set extremely high. Just get access to the thermostat and change as required. This may also be required when the season changes from cold to warm.

If you cannot adjust the water temperature as required, you may need to replace your thermostat or there may be some type of electrification issue.

Water Takes Much Time to Reheat

If the water heater is taking a longer time than usual to reheat the water, there may be a problem with the heating elements or sediment build-up on the element or maybe an issue thermostat and these parts may need to be replaced.
