Water heater running constantly? discover the root cause
What To Know
- If the heating element fails, it will not be able to heat the water to the desired temperature, causing the water heater to run continuously in an attempt to reach the set temperature.
- A leak in the water heater tank or plumbing system can cause water to escape, resulting in a drop in water pressure.
- If the pressure relief valve fails, it may allow water to leak out, causing a drop in water pressure and triggering the water heater to run constantly.
Water heaters are an essential part of any home, providing us with the comfort of hot water when we need it. However, when your water heater starts running constantly, it can be a frustrating and expensive problem. In this comprehensive blog post, we will explore the various reasons why your water heater may be running continuously and provide solutions to resolve the issue.
Common Causes of a Constantly Running Water Heater
1. Failed Thermostat: The thermostat is responsible for regulating the temperature of your water heater. If the thermostat fails, it may send incorrect signals to the heating element, causing it to run constantly.
2. Faulty Heating Element: The heating element is the component that heats the water in your water heater. If the heating element fails, it will not be able to heat the water to the desired temperature, causing the water heater to run continuously in an attempt to reach the set temperature.
3. Sediment Buildup: Over time, sediment can accumulate in the bottom of your water heater tank. This sediment can insulate the heating element, preventing it from effectively heating the water. As a result, the water heater may run constantly in an attempt to overcome the insulation.
4. Leaks: A leak in the water heater tank or plumbing system can cause water to escape, resulting in a drop in water pressure. To compensate for the lost pressure, the water heater may run continuously to refill the tank.
5. High Water Demand: If you have multiple appliances or fixtures using hot water simultaneously, it can overwhelm the capacity of your water heater. This can cause the water heater to run constantly in an attempt to meet the high demand.
6. Incorrect Water Temperature Setting: If the water temperature on your water heater is set too high, it may cause the water heater to run more frequently than necessary.
7. Faulty Pressure Relief Valve: The pressure relief valve is a safety feature designed to release excess pressure from the water heater. If the pressure relief valve fails, it may allow water to leak out, causing a drop in water pressure and triggering the water heater to run constantly.
Troubleshooting and Solutions
1. Check the Thermostat: Use a multimeter to test the thermostat for continuity. If there is no continuity, replace the thermostat.
2. Inspect the Heating Element: Remove the heating element and check for any signs of damage or corrosion. If the heating element is damaged, replace it.
3. Flush the Water Heater: Drain the water heater and flush out any sediment using a garden hose.
4. Repair or Replace Leaks: Inspect the water heater tank and plumbing system for any leaks. Repair or replace any leaking components.
5. Reduce Hot Water Demand: stagger the use of hot water appliances or reduce the flow rate of hot water fixtures.
6. Adjust the Water Temperature: Lower the water temperature on your water heater to a more appropriate setting.
7. Replace the Pressure Relief Valve: If the pressure relief valve is leaking or faulty, replace it with a new one.
Prevention Tips
1. Regular Maintenance: Schedule regular maintenance for your water heater to prevent sediment buildup and other potential issues.
2. Use a Water Softener: If your water is hard, a water softener can help reduce sediment buildup in your water heater.
3. Set the Water Temperature Correctly: Avoid setting the water temperature too high, as this can shorten the lifespan of your water heater.
4. Insulate the Water Heater: Insulating your water heater can help reduce heat loss and improve efficiency.
5. Consider a Tankless Water Heater: Tankless water heaters provide hot water on demand, eliminating the need for a constantly running water heater.
When to Call a Plumber
If you are unable to resolve the issue on your own, or if you suspect a more serious problem, it is important to call a qualified plumber. Plumbers have the expertise and tools to diagnose and repair water heater problems safely and effectively.
Wrapping Up

By understanding the common causes and troubleshooting tips in this blog post, you can take steps to resolve the issue and restore your water heater to proper operation. Remember, regular maintenance and preventive measures can help extend the lifespan of your water heater and prevent future problems.
Frequently Asked Questions
Q: Why does my water heater run for hours after I turn off the hot water?
A: This could be due to a failed thermostat or heating element, causing the water heater to continue heating water unnecessarily.
Q: Can a faulty pressure relief valve cause my water heater to run constantly?
A: Yes, a leaking or faulty pressure relief valve can allow water to escape, triggering the water heater to run continuously to maintain water pressure.
Q: How often should I flush my water heater?
A: It is recommended to flush your water heater every 6-12 months to remove sediment buildup.
