Tips for Maintaining Your Hot Water Heater in Riverside

Understanding Your Hot Water Heater

Types of Hot Water Heaters Commonly Found in Riverside Homes

In Riverside, homeowners typically use three main types of hot water heaters: tankless, gas, and electric. Each type offers distinct benefits and operates on different principles:

  1. Tankless Water Heaters: Known for their efficiency, tankless water heaters heat water on demand rather than storing it. This not only conserves energy but also provides a continuous supply of hot water, making them popular among energy-conscious Riverside residents.
  2. Gas Water Heaters: These are traditional water heaters with a tank. They are generally more cost-effective to operate than electric heaters, given the lower cost of natural gas in many parts of California.
  3. Electric Water Heaters: Unlike gas heaters, these units use electrical elements to heat water stored in a tank. They are simpler to install and maintain but can be more expensive to operate due to electricity pricing.
Basic Components of a Hot Water Heater and How They Work

Understanding the basic components of your hot water heater, whether it’s tankless, gas, or electric, can help you better maintain the unit and troubleshoot minor issues. Here are the key components:

  1. Heating Element (Electric) / Gas Burner (Gas): In electric heaters, submerged heating elements directly heat the water. In gas heaters, a burner heats the water indirectly through a heat exchanger.
  2. Thermostat: This component regulates the temperature of the water in the tank, ensuring it remains within a safe and efficient range.
  3. Dip Tube: Water enters the tank through the dip tube and is directed to the bottom where it’s heated.
  4. Heat-Out Pipe: Positioned at the top of the tank, this pipe allows the hot water to exit the tank and be distributed throughout your home.
  5. Pressure Relief Valve: This safety device helps to relieve pressure if it builds up too high inside the tank, preventing potential damage or explosions.
  6. Drain Valve: Located near the bottom of the tank, the drain valve allows for the tank to be emptied for maintenance or troubleshooting.

Regular Maintenance Tips

Maintaining your hot water heater is crucial for ensuring it operates efficiently and safely. In Riverside, CA, where mineral deposits from hard water can accelerate wear and tear, scheduling an annual inspection with a professional plumber is particularly important.

The ideal temperature setting for your hot water heater typically strikes a balance between energy efficiency and the need to minimize the risk of harmful bacteria, like Legionella, which thrives in warmer waters. Here are key considerations:

  1. Energy Efficiency: Setting your water heater at 120 degrees Fahrenheit is generally recommended for most households. This temperature is hot enough to meet daily needs without being wasteful. It reduces the risk of mineral buildup and corrosion, which are common in areas with hard water, such as Riverside.
  2. Safety Considerations: At 120 degrees, the risk of scalding is significantly lower than at higher temperatures, making it a safer option for homes with children and elderly individuals. However, it’s high enough to inhibit the growth of Legionella bacteria, which can cause serious health issues.

How Riverside Residents Can Adjust Their Settings Seasonally to Save on Energy Bills

Riverside’s climate, characterized by hot summers and mild winters, provides unique opportunities to adjust your hot water heater settings seasonally:

  1. Summer Adjustments: During the hot summer months, Riverside residents can often manage with slightly cooler water. Lowering the temperature setting on your water heater to just below 120 degrees can help reduce energy usage, as the ambient warmer temperatures mean less energy is needed to heat the water to the desired level.
  2. Winter Adjustments: In the cooler winter months, residents might feel the need for slightly warmer water. Adjusting the temperature up a few degrees can help provide comfort without a significant increase in energy consumption. However, it is crucial to never set the heater above 140 degrees Fahrenheit to avoid the risk of scalding and increased energy waste.
  3. Year-Round Tips: To ensure optimal performance and energy savings throughout the year, consider installing a programmable thermostat for your water heater if it does not already have one.

3. Draining and Flushing the Tank

Regularly draining and flushing the tank of your hot water heater is essential for removing sediment buildup, which can impair its efficiency and shorten its lifespan. Homeowners in Riverside, CA, dealing with hard water, should pay particular attention to this maintenance task.

Step-by-Step Guide on How to Drain and Flush the Tank

Materials Needed:

  • Garden hose
  • Bucket (for testing)
  • Gloves and goggles (for safety)
  • Screwdriver or similar tool (if needed for accessing the drain valve)


  1. Turn Off the Water Heater: For electric heaters, turn off the power at the circuit breaker. For gas heaters, set the thermostat to the “pilot” setting.
  2. Connect a Garden Hose to the Drain Valve: Locate the drain valve at the bottom of the tank. Attach a garden hose to the valve. Ensure the other end of the hose is in an area where hot water can safely discharge, like a driveway or basement drain.
  3. Turn Off the Cold Water Supply: Shut off the cold water supply to the water heater to stop more water from entering the tank.
  4. Open the Hot Water Tap: Open a hot water tap nearest to the water heater. This prevents a vacuum from forming in the pipes and allows the tank to drain more efficiently.
  5. Open the Drain Valve: Allow the water to flow from the tank into the discharge area. Be cautious, as the water will be hot.
  6. Flush the Tank: Once the tank is empty, briefly turn on the cold water supply to the tank to flush any remaining sediment. This might need to be repeated several times until the water runs clear.
  7. Close the Drain Valve: Once the water runs clear, close the drain valve.
  8. Refill the Tank: Turn on the cold water supply to the tank and wait for the tank to fill. Check the open hot water tap; once water flows out smoothly, this indicates the tank is full.
  9. Turn the Water Heater Back On: For gas heaters, turn the thermostat back to the desired setting. For electric heaters, restore power at the circuit breaker.
  10. Check for Leaks: Inspect the area around the water heater for any leaks from the drain valve or other components.

Frequency of This Maintenance Task and Its Benefits


  • General Recommendation: It’s advised to drain and flush your hot water heater at least once a year. However, in areas with hard water, such as Riverside, CA, performing this maintenance twice a year may be beneficial to combat the faster buildup of sediment.


  • Efficiency and Longevity: Removing sediment buildup helps maintain the efficiency of your water heater. Sediment acts as an insulator, reducing the heater’s ability to heat water efficiently, thus forcing it to work harder and use more energy.
  • Prevention of Damage: Sediment can cause corrosion and increase the likelihood of leaks and failures. Regular flushing helps prevent these issues, extending the lifespan of the unit.

4. Checking the Anode Rod

Explanation of the Anode Rod’s Role in Preventing Corrosion

The anode rod, often made from magnesium or aluminum, plays a critical role in protecting the water heater from rusting. This rod attracts corrosive elements in the water, which are otherwise likely to attack the steel tank and cause it to rust. The anode rod sacrifices itself by corroding in place of the tank—hence why it’s often referred to as a “sacrificial rod“.

How Often to Check and Potentially Replace the Anode Rod

Frequency of Checks:

  • General Recommendation: It’s advisable to check the anode rod at least once every year. However, the specific frequency can vary based on several factors, including water quality, water heater usage, and the model and make of the water heater.
  • In Riverside, CA: Given the hardness of the water in many parts of Riverside, it’s wise to inspect the anode rod more frequently. Hard water can accelerate the corrosion process, shortening the life expectancy of the anode rod.

Steps to Check the Anode Rod:

  1. Turn off the Power and Water Supply: Before checking the anode rod, ensure the power to an electric heater is turned off or the gas valve is set to “pilot” in gas models. Also, shut off the cold water supply to the heater.
  2. Drain Some Water from the Tank: This reduces pressure and prevents hot water from splashing during the removal of the anode rod. Draining a few gallons is generally sufficient.
  3. Locate and Remove the Anode Rod: The anode rod is typically attached to the top of the tank. Use a socket wrench to loosen and remove it.
  4. Inspect the Anode Rod: Check for any excessive wear or corrosion. If more than half of the rod has been corroded, or if it’s coated with calcium, it needs to be replaced.

Replacing the Anode Rod:

  • If the anode rod shows significant wear, replace it with a new one that matches the specifications recommended by the heater’s manufacturer. Insert the new rod, secure it tightly, and ensure the area is sealed to prevent leaks.

5. Inspecting Pressure Relief Valve

Importance of Ensuring the Pressure Relief Valve Is Functioning

The pressure relief valve, also known as the temperature-pressure (T&P) relief valve, is designed to open and release water if either the temperature or pressure inside the tank becomes too high. This functionality is critical as it helps prevent potential damage to the water heater and surrounding property, and more importantly, it avoids possible injury to homeowners and residents from tank ruptures.

Instructions for Testing the Valve Safely

Safety Precautions: Before testing the pressure relief valve, ensure your safety and that of your property with these precautions:

  • Turn off the power to the water heater: If it’s electric, switch it off at the circuit breaker. For gas water heaters, turn the setting to “pilot.”
  • Prepare the area: Make sure the area around the discharge pipe is clear, as hot water will be released during testing.

Steps to Test the Pressure Relief Valve:

  1. Locate the Valve: The pressure relief valve is typically located on the top or side of the tank, with a discharge pipe running down to the floor.
  2. Check the Discharge Pipe: Ensure it is not blocked and leads to an area where hot water can safely exit, typically to a drain or outdoors.
  3. Lift the Lever Carefully: Slowly lift the test lever on the valve to open it manually. You should hear a rush of air or see some water and vapor exit through the discharge pipe. This indicates the valve is operating correctly.
  4. Observe the Flow: As you lift the lever, watch the discharge. Water should flow freely and stop when you release the lever, indicating the valve is functioning correctly.
  5. Check for Leaks: After testing, release the lever and observe the valve for any leaks. If it continues to drip water, it may not be sealing correctly, and it might need cleaning or replacement.

Frequency of Testing:

  • General Recommendation: Test the pressure relief valve at least once a year to ensure it functions correctly.
  • In Riverside, CA: Due to water hardness and frequent shifts in usage patterns between seasons, consider testing the valve biannually to safeguard against the faster accumulation of mineral deposits, which can impair valve function.

6. Insulating Older Units

In Riverside, where temperatures can vary significantly, insulating older hot water heaters and their pipes is a cost-effective way to increase energy efficiency and reduce heating costs. This guide outlines the benefits of insulation and recommends suitable materials for homes in Riverside.

Benefits of Insulating Older Hot Water Heaters and Associated Piping

  1. Reduced Heat Loss: Insulation helps maintain the temperature of the water in the heater, reducing the energy needed to reheat the water. This is particularly beneficial during cooler months in Riverside, where without insulation, significant heat can be lost from the tank and pipes.
  2. Energy Cost Savings: By maintaining the water temperature for longer periods, an insulated water heater requires less energy to heat the water. Homeowners can see a noticeable reduction in their monthly utility bills.
  3. Extended Lifespan: Insulation reduces the workload on the water heater by minimizing the cycling frequency (the turning on and off of the unit), which can wear out components over time. This helps extend the lifespan of the unit.
  4. Increased Comfort: Insulating the pipes minimizes the wait time for hot water to reach faucets and showers. This not only enhances comfort but also conserves water, which is beneficial in water-scarce areas like Riverside.

Types of Insulation Materials Recommended for Riverside Homes

When choosing insulation for an older water heater and its pipes, selecting the right materials is crucial for effectiveness and durability. Here are the recommended types of insulation materials suitable for Riverside homes:

  1. Water Heater Blankets: For the tank itself, fiberglass water heater blankets are highly effective. They are designed to fit around the tank snugly, providing a substantial barrier against heat loss. These blankets are rated by R-values— the higher the R-value, the better the insulation properties.
  2. Foam Pipe Insulation: For the pipes, closed-cell foam insulation is recommended. This material is easy to install — it typically comes in tubes that can be cut to length and wrapped around the pipes. Foam insulation is ideal for maintaining the temperature of the water as it moves through the pipes.
  3. Reflective Foil Insulation: This is another option for both tanks and pipes, especially effective in reflecting heat back into the water heater and pipes. Reflective foil insulation is lightweight, easy to install, and particularly useful in areas exposed to direct sunlight.
