Flush Your Water Heater Every Six Months


The most impactful maintenance service you can provide to your water heater is to regularly flush it out. This keeps the hard water mineral in Wisconsin water from building up on the bottom of your water heater. Lime, scale and calcium will eventually build up and decrease the efficiency of the heater and cause stress on the tank. 

Pro Tip- Put a reminder on your phone to flush the water heater or join our maintenance program

Check the Water Heater Anode Rod Annually

Inside the water heater is the sacrificial anode rod. This is a tank protecting device that breaks down as water attacks it, saving your water heater tank from being attacked. If the anode rod depletes and there is no anode to attack, the water will go to work on the water heater tank which is why it is critical to make sure that the anode road is intact.

Pro Tip- Use a high torque impact driver to remove the anode rod and the proper amount of teflon tape and pipe thread sealant when you reinstall it.

The Importance of Water Heater Maintenance

Each manufacturer of water heaters has their specific annual maintenance items. We find that most manufactures expect you to test, inspect or adjust critical parts of the water heater in order to increase performance and life of your water heater. Below are some common items that we routinely check during yearly water heater tune-ups

This is a critical safety component of the heater that should be tested annually.

This is a consumable piece of the water heater that deteriorates over time. When it's gone, the water will deteriorate the water heater tank, so it's important to monitor the condition of the anode rod to prolong the life of the heater.

During normal use, sediment builds up on the bottom of your hot water tank which makes the unit inefficient and more prone to leaking. This sediment should be flushed out annually.

Because of the carbon monoxide risk associated with all gas appliances, a thorough inspection of the combustion chamber and associated gas pipe should be done for safety annually.

If the water pressure in your tank gets higher than the maximum of 80 PSI, your water heater is destined for a short life. Your home's water pressure should be tested annually to make sure it's under the code maximum.
