Signs Your Water Heater Is Soon Going to Fail

By identifying an issue with your tankless water heater earlier, you can prevent it from worsening and causing significant damage. It also aids in extending the lifespan of the unit by around 3 to 5 years.

However, it is best to entrust the tasks of repair and maintenance to an efficient tankless water heater repair service in Irving, TX. Professionals take all safety measures and use the right techniques to solve the issue quicker and more effectively.

Look out for the indications that your tankless water heater is going to fail and take timely action.

Insufficient Hot Water

Do you notice that lately, your tankless water heater is taking too long to heat water? Or is the water constantly lukewarm? These are among the most common signs of a failing tankless water heater. Your unit holds gallons of water. Whenever you use more hot water, it refills and reheats water.

Generally, it reheats quickly to supply enough hot water for you. If its heating elements do not function efficiently, it does not produce adequate hot water. The issue can also be with the other internal components, such as the pilot light.

Contact a tankless water heater service to inspect your unit. Plumbers find the malfunctioning part and repair it before the damage spreads to other components.

Knocking or Rumbling Noises

Water heaters may make a sound while heating water. However, if you hear any unusual sounds, such as knocking or rumbling noises, something may be wrong within the unit. The most common reason is sediment accumulation. The build-up moves around noisily while water flows around it.

The constant movement of the accumulation may damage the walls of your tankless water heater. It leads to cracks and water leakages.

Any broken tubes and parts within the unit also produce unusual noises. Ensure not to ignore the issue. Hire a tankless water heater repair service to clean the unit or repair the broken parts.

Fluctuating Temperatures

Do you find the water temperatures too high or too low frequently? It is another tell-tale sign of a failing tankless water heater. Various issues within the unit can cause inconsistent temperatures.

The most common reasons include:

  • Malfunctioning heating elements
  • Accumulation of mineral deposits over the heating elements
  • Exhausted thermostat
  • Damaged internal components
  • Aging water heater
  • Insufficient hot water because of excess use

Hire an experienced water heater repair service to inspect your unit and identify the cause. Professionals replace the faulty parts with sturdier and more durable ones. If your tankless water heater is aging, you need to purchase a new unit. Your plumber suggests efficient models in the market that meet your needs and budget.


Water pooling around the tankless water heater and the floor is an indicator of a leaking unit. The pipes that connect to your device may be leaking because of higher water pressure or other damage. The unit may also leak if it suffers from corrosion.

Make sure to stop the water from pooling excessively. It soon leads to flooding and significant water damage. Try to collect the water in a container and call a tankless water heater service immediately.

You have to be cautious and avoid coming into contact with any electrical wires, appliances, or the water around the affected area. If water begins to flood, you can call emergency service for prompt repairs any time of the day.

Change in Water Color

A sudden change in the hot water color to a rusty brown or red indicates underlying issues in your water heater. Sediment build-up in the unit usually leads to water discoloration. The watercolor may also change as it passes through corrosive pipes.

A tankless water heater repair service examines your unit and cleans it. Your plumber installs pipes that are less prone to rusting, such as PVC (Polyvinyl Chloride) or copper pipes.

Decrease in Water Pressure

A dramatic drop in the water pressure, while you shower, is also a sign of faulty internal components. The most likely reason is the accumulation of deposits on the tankless water heater’s heating elements. The blockage may soon stop your water flow if you delay clearing it.

A poor setup of pipes may also lower water pressure. A tankless water heater repair service ensures to return the pressure to normal by removing the deposits. If the plumber finds the pipe design ineffective, they may replace it as well.

Unpleasant Odor

Deteriorating components in your tankless water heater may give rise to an unpleasant or metallic odor. Its metal elements erode and flow along with the water through your pipes.

Bacterial infection in the unit also causes a bad odor. Contact a tankless water heater repair service to detect the issue and resolve it promptly.
