Expert Water Heater Maintenance Tips by Wooten Knockout Plumbing

A well-functioning water heater is essential for any home to provide hot water for showers, laundry, and washing dishes. Regular maintenance plays a crucial role in ensuring the efficiency and longevity of your water heater. In this blog post, we will discuss essential water heater maintenance tips and how Wooten Knockout Plumbing’s expert services can assist in keeping your water heating system running efficiently and effectively for years to come.

Water heaters can be categorized into two main types: tank and tankless. While both types serve the same purpose of providing hot water, their maintenance requirements may slightly differ. Tank water heaters store hot water in a tank and need consistent temperature regulation to ensure a ready supply, whereas tankless water heaters heat water on demand, providing energy savings and endless hot water supply. Despite their differences, both types require regular maintenance to prevent potential issues that may lead to costly repairs or premature system failure.

Proactive maintenance and regular inspection of your water heater can prevent problems such as sediment buildup, corrosion, and leaks, which can significantly impact the efficiency and performance of your system. Additionally, proper maintenance can also extend the lifespan of your water heater, helping you save on replacement costs and ensuring a consistent supply of hot water for your daily needs.

In the following sections of this blog post, we will discuss specific preventive maintenance tips, including inspecting and flushing the tank, checking the pressure relief valve, and ensuring proper temperature settings. Moreover, we will demonstrate how Wooten Knockout Plumbing’s professional maintenance services can provide you with peace of mind, knowing your water heater is in optimal condition, minimizing the risk of unexpected issues and prolonging the life of your system.

Essential Water Heater Maintenance Tips

1. Inspecting and Flushing the Tank

Regularly inspecting and flushing your water heater tank can significantly improve its performance and prevent potential problems. Over time, sediment and mineral deposits can accumulate in your tank, reducing its capacity and causing the heating element to work harder, leading to increased energy consumption and potential damage. Experts recommend annually draining and flushing the tank water heater to remove these sediments and maintain the system’s efficiency.

For tankless water heaters, flushing and descaling the system at least once a year is essential to remove any mineral buildup and maintain optimal performance. Consult your user’s manual or enlist the assistance of a professional plumber for specific flushing instructions for your system.

2. Checking and Replacing the Anode Rod

The anode rod is a crucial component in tank water heaters. It serves to protect the tank from corrosion by attracting corrosive elements in the water, thus sacrificing itself to preserve the tank’s integrity. Typically made of magnesium or aluminum, the anode rod can deteriorate over time and need replacement to ensure continued protection.

Inspect your anode rod annually by turning off the power and partially draining the tank, then carefully removing the rod. If it appears to be coated in calcium deposits or has corroded to a significant extent, it’s time for a replacement. This simple maintenance step can significantly extend the life of your tank water heater.

3. Testing the Pressure Relief Valve

The pressure relief valve is a critical safety feature found in both tank and tankless water heaters. This valve is designed to release excess pressure within the system, preventing potential damage or a dangerous explosion.

At least once a year, test the pressure relief valve by carefully lifting the lever and allowing it to snap back into place. You should hear a gurgling sound as water is released through the valve. If no water is discharged or the valve appears to be leaking, it may be time to replace the valve.

4. Adjusting the Temperature Setting

Proper temperature settings are essential for optimal water heater performance and energy savings. By lowering your water heater’s temperature setting, you can reduce energy usage and prevent scalding. A temperature of 120°F (49°C) is typically recommended for most households.

For tankless water heaters, adjusting the temperature settings as needed can also help maintain optimal performance. Keep in mind that you may need to adjust these settings based on the number of appliances simultaneously using hot water or the temperature of the incoming water supply.

5. Insulating the Water Heater and Pipes

Insulating your water heater tank and hot water pipes can significantly reduce heat loss, thereby saving energy and maintaining the desired hot water temperature. For tank water heaters, insulating blankets or jackets specially designed for water heaters can be wrapped around the tank to minimize heat loss. It’s crucial to follow the manufacturer’s instructions when insulating your tank, as improper installation can lead to safety hazards.

For both tank and tankless systems, insulating your hot water pipes will also minimize heat loss and maximize energy efficiency. Pipe insulation is available in various materials, such as foam, fiberglass, or rubber, and can typically be installed quickly and easily.


Proactive water heater maintenance is essential to keep your system running efficiently and extend its lifespan. Regularly inspecting and flushing the tank, checking and replacing the anode rod, testing the pressure relief valve, adjusting the temperature settings, and insulating your water heater and pipes are crucial steps in ensuring the performance and longevity of your system.
