Maximize Efficiency: Tips for Maintaining Your Water Heater Recirculating Pump

Installation of a water heater recirculating pump is a wise decision. Its efficient operation is useful for the longevity of the appliance. To maintain efficiency, there are many things as a user that you can do. The best tips for maintaining your water heater recirculating pump are provided in the blog. 

Professional maintenance comes with a cost and is periodic while self-maintenance tips are inexpensive and easy to perform.

Let us begin by understanding the basics. 

• For easy identification of potential issues and the process of maintenance, let us understand the operation mechanism of the water heater recirculating pump.
• The water heater circulates hot water directly to the fixtures and faucets without waiting for long.  
• As the waiting period is no longer there, this specialty reduces the wastage of water.

Here are the Best Tips to Maintain Your Water Heater Recirculating Pump: 

1. Regular Inspection:

Regular inspection involves the following checkpoints:

• Check the connections for any water leaks around the pump. These leaks may be due to loose fittings, damaged seals, or other issues.
• Listen for any strange or loud noises coming from the pump. Unusual sounds may signal motor problems or debris inside the pump.
• Feel for excessive vibrations while the pump is running. Vibrations can damage the pump and its mounting over time.
• Examine the pump and its components for any visible signs of damage, such as cracks or corrosion.

2. Lubrication:

Some recirculating pumps may require periodic lubrication to maintain smooth operation. If lubrication is necessary, follow these steps:

• Disconnect the pump from the power source.
• Locate the lubrication points on the pump (usually marked in the manual).
• Apply a few drops of pump-specific lubricant to these points. Do not over-lubricate to prevent the sticking of dust and debris.  
• Now, reconnect and test the pump for smooth running. 

3. Cleaning:

Here are the cleaning steps for recirculating the pump of the water heater:

• Turn off the power to the pump and disconnect it from the power source.
• Remove the pump housing or cover to access the impeller and internal components.
• Use a soft brush or compressed air to remove dust and debris from the impeller and surrounding areas.
• Now, check any signs of damage in the impeller. Use the manufacturer's instructions for replacing the valve.
• Clean the housing or cover before reassembling the pump.
• Now, connect the power source again and test the pump for its smooth working.

4. Flushing the System:

Flushing the entire recirculating system is essential to remove sediment and mineral buildup that can affect pump performance and reduce the efficiency of your water heater. 

Here is how you flush the system:

• Turn off the power to the pump and unplug
• Locate the drain valve on the water heater (The lowest point in the recirculating system is the drain valve).
• Be ready with a bucket under the drain valve to fill the water.
• Now, open this drain valve to allow the water to flow out for some time. This water carries sediment and debris out from the system.
• Close the drain valve and reconnect the power source to the pump.
• Check the pump for its correct working.
• Flushing of the water heater recirculating pump should be a biannual process. You may do this more often if the supply of water is hard. 

5. Inspect the Check Valve:

The check valve prevents cold water from flowing backward into the hot water line. This ensures that hot water is readily available at the tap. The check valve is located at a point on the water heater, where the hot water line returns to the heater. Inspect the check valve as part of your maintenance routine:

• Ensure the power to the pump is turned off and disconnected.
• Locate the check valve in the recirculating system
• Any damage, leaks, or corrosion should be checked on the valve. Replace the check valve if necessary.
• After replacing, test the check valve to ensure it is functioning correctly. Now, blow air into the valve. Airflow in a single direction means there is no damage. 
• Reconnect the power source to the pump and check that it is working properly.

6. Check for Air in the System:

Accumulation of air can also reduce the efficiency of the recirculating system over time.

This is how you can check and remove air from the system:

• Turn off the power to the pump and unplug.
• Locate the air bleed valve, which is often situated on the top of the recirculation line or pump.
• Slowly open the air bleed valve to release any trapped air. Be prepared for water to flow out as well.
• Keep the valve open until water flows steadily without air bubbles.
• Now, close the air bleed valve.
• Reconnect the power source to the pump and test it for its smooth functioning.

7. Verify the Timer Settings:

If your pump has a timer system, correct the configuration settings of the recirculating pump. This system is in conventional models that do not operate on demand.

The timer should be set to circulate hot water for the times you typically need it. Adjust the timer to match your daily schedule.

8. Maintain the Hot Water Heater:

Proper maintenance of your water heater is indirectly connected to the performance of the recirculating pump. Ensure that the water heater is in good working condition by flushing it biannually, noticing any leakage or damage, and promptly responding to it. Further, insulate the water heater properly to minimize heat loss.

9. Water Quality:

If you have hard water with a high mineral content, you may need to address it to prevent mineral buildup in the pump and system. Consider installing a water softener or using a descaling agent as required. 

In conclusion, the importance of maintaining a water heater recirculating pump cannot be overstated. Regular maintenance not only saves you money and conserves resources but also ensures your comfort, convenience, and safety.  Call EZ Plumbing USA for the best hot water recirculation system services
