1. Flush the Tank to Remove Sediment

Over time, sediment naturally builds up at the bottom of your water heater tank, especially in areas with hard water. This sediment buildup can cause your water heater to work harder, leading to reduced heating efficiency, causing strange noises, and eventually damaging the tank. Flushing your water heater annually helps remove this mineral buildup and improves its efficiency. Here is a step-by-step guide to flushing your Tank:

1. Turn off the power or gas supply.
2. Attach a hose to the drain valve, allowing water and sediment to drain into a safe location.
3. Open the drain valve and let the water flow until it runs clear. 
4. Close the valve, refill the tank, and restore power or gas to the unit. 

This method reduces energy costs, improves heating efficiency, and extends the life of your water heater. If you’re unsure about performing this task, or your system hasn’t been maintained in a while, it’s a good idea to call a professional plumber. 

2. Replace the Anode Rod Periodically

The anode rod in your water heater is a crucial component in preventing corrosion. It is usually made from materials like magnesium or aluminum and attracts minerals and other corrosive elements, protecting the tank from rusting. Over time, the rod degrades, and if neglected, it can lead to tank rust and leaks. To keep your water heater in good condition, check the anode rod now and then. Here is how to know when to replace the anode rod:

• Check every 3 to 5 years by turning off the unit for wear and tear.
• Look for corrosion, significant erosion on the rod, coated with calcium, or if the rod is reduced to less than half an inch in diameter.
• Install a new anode to prolong the life of your tank.

Replacing the anode rod helps extend the life of your tank, prevents leaks, maintains water quality, and can help you avoid costly repairs. If you’re not confident in handling the task, consider calling a professional plumber to ensure it’s done correctly and safely. 

3. Test the T&P Valve Monthly

The Temperature and Pressure (T&P) valve is a crucial safety feature of your water heater that protects the tank from excessive pressure or temperature, helping prevent the tank from overheating or even exploding. To ensure that it is working correctly and help avoid any dangerous failures, monthly testing should be done.  Follow these steps to test the T&P Valve:

1. Locate the valve on your water heater.
2. Lift the test lever briefly and listen to water discharging through the pipe.
3. Release the lever and let the water flow stop, and ensure the valve reseals properly.
4. Check for any leaks or malfunctions. 

If the valve doesn’t release water or leaks, doesn’t reseal properly, or starts dripping, it may be faulty and should be replaced immediately. Call for a professional inspection if you’re unsure about how to test it.  

4. Adjust the Temperature to Safe Levels

Fixing your water heater’s temperature to the correct temperature is essential for both health and safety. Setting it too high can lead to scalding accidents, while too low a temperature may not kill harmful bacteria like Legionella, which thrives in lukewarm water. To avoid these issues, the recommended temperature for your water heater should be set at 120°F (49°C).How to Adjust the Temperature: 

1. Turn off the power and locate the thermostat on your water heater.
2. Adjust the setting to 120°F for optimal safety and efficiency. 

Proper and safe temperature control not only helps prevent burns and the risk of bacteria, but also promotes energy savings. If your heater has dual thermostats (upper and lower), make sure both are set correctly at the same temperature for consistent performance. 

5. Check for Leaks Around the Unit

Leaks around your water heater can cause significant water damage to your home. Detecting leaks early helps prevent water damage, costly system failure, or mold growth. It’s essential to inspect the area around your water heater regularly to detect hidden leaks early. Where to Look for Leaks:

• Check the drain valve or base of the unit for signs of moisture or pooling water.
• Inspect fittings and connections for corrosion or leaks.
• Look under the insulation for water puddles, rust stains, or moisture marks indicating a hidden leak. 

If you find any leaks, call a professional for repair immediately, as small leaks can quickly worsen into costly repairs. Early intervention and regular maintenance help you protect your home and can save you from major water damage. 

6. Insulate the Pipes and Tank for Efficiency

Proper insulation of your water heater tank and pipes significantly improves energy efficiency. It reduces standby heat loss and prevents pipe freezing, especially in colder climates. Also, insulating your system can boost efficiency and save energy, keep water hot for longer periods, and reduce your utility bills. Here are some insulation tips for homeowners: 

1. Use foam pipe sleeves for the first 3 feet of hot and cold water pipes.
2. Wrap your water heater tank with a tank blanket with a suitable R-value (typically R-8 or higher).
3. Ensure the R-value of the insulation is suitable for your climate.

By properly insulating your water heater, you can increase its efficiency by 4–9%, leading to noticeable energy savings, faster hot water recovery, and avoiding the inconvenience of frozen pipes during winter.  If you’re unsure of the process, consult with a professional to ensure safe insulation and compliance with safety standards. 

7. Clean the Air Intake Filter on Tankless Systems

Tankless water heaters depend on clean airflow for efficient and proper combustion and heating; hence, a clogged or dirty air intake filter can restrict airflow, causing overheating or even shutdown. Regularly cleaning the air intake filter ensures the unit operates at peak efficiency, preventing blockages. How to Clean the Air Intake Filter:

1. Turn off the unit, allow it to cool down, and remove the filter after cooling.
2. Carefully remove it and either clean it with warm water or replace the filter as needed.
3. Check for dust, debris, or blockages in the air intake vent to ensure optimal performance.

Air filter inspection and maintenance should be done every 6 to 12 months, depending on the indoor air quality and usage. Neglecting it for a long time can lead to reduced efficiency or complete system failure. If you notice any damage or are unsure about the cleaning process, schedule a professional servicing and keep your system running.

8. Inspect the Pressure Relief Valve

The pressure relief valve (PRV) is another critical safety feature of a water heater that helps release excess pressure, preventing the tank from overheating or potential explosion. Proper and timely inspection of this valve is essential to ensure your water heater remains safe to use, protecting both your home and your system. How to Inspect the Pressure Relief Valve:

1. Locate the valve near the top or side of the tank.
2. Test the lever to ensure water flows when lifted.
3. Look for signs of corrosion, rust, mineral buildup, or leaks.
4. If water continues to discharge after testing, the valve may need replacing.

This is one of the most important safety checks of the PRV, especially needed for systems where parts may wear out over time. If you notice any issues, it’s critical to replace the valve immediately by consulting a professional plumber to inspect or replace it safely. 

9. Schedule a Professional Inspection Annually

While DIY maintenance can keep your water heater running smoothly, it’s crucial to have a professional inspection once a year and identify hidden problems. To ensure your water heater remains safe and efficient, certified technicians detect potential issues that might not be obvious during routine checks, ensuring your system operates efficiently and safely. Here is what a professional technician checks during inspection:

• Internal corrosion, test burner, or heating element performance. 
• Inspect valve function, verify thermostat calibration, and inspect the anode rod.
• They also look for hidden leaks and pressure tests. 

This type of professional inspection can catch hidden problems before they become costly repairs, and experts recommend doing it at least once a year. While hiring professionals, look for certified plumbing inspectors and trusted licensed local plumbers for expert servicing, and saving you money in the long run.
