Common Warning Signs of a Faulty Water Heater
A household’s water heater is an important part of daily life for its residents. But sometimes, it is hard to know when a water heater needs service from a professional plumber. Sure, there are obvious signs like visible leaks or the loss of hot water, but there are other signs homeowners can keep an eye out for, indicating that water heater repair, maintenance, or replacement may be needed. This post will share other signs to help homeowners determine when to call a professional and get their water heater serviced.
A More Expensive Utility Bill

If a water heater has not had its routine water heater maintenance, it could have excess sediment that needs to be flushed out, causing inefficiency. If a water heater is old, it could also be the reason it’s working inefficiently and causing higher costs. The unit could also be malfunctioning and in need of water heater repair, causing it to consume more energy and raise costs. So, higher utility bills can be a red flag that water heater replacement, maintenance, or repair is needed.
The Water Heater Makes Noise

- Popping: Popping sounds from the water heater can indicate a buildup of sediment inside the water heater’s tank, which requires maintenance to drain and flush the water heater.
- Sizzling or hissing: These noises could be from sentiment buildup, especially if it is an electric water heater. It could also be due to water or moisture on the outside of the water heater, especially if it is a gas water heater.
- Banging: A banging sound can indicate a water hammer, resulting from excess pressure in the water heater when the water is forced to stop or change direction quickly. Banging noises can also indicate excess sediment in the water heater that is reacting with the heating element.
- Humming or vibrating: These sounds from the water heater could mean that there is a loose valve, fixtures, or even the heating element.
The Water Has a Strange Color or Smell
Cloudy or discolored hot water or hot water with a strange smell are also signs that a water heater needs service from a plumber. A rusted and corroded water heater can cause the water to be discolored and appear brown or a rusty orange-brown color and can also cause the water to have an unusual, metallic smell.
Bacteria growing inside the water heater can also cause the hot water to have a strange smell. If the water heater is corroded, it will likely need water heater replacement because corrosion can weaken the water heater’s structural integrity and make it more prone to leaks and problems. A professional can inspect the water heater and decide the best course of action.
