Essential Water Heater Maintenance Tips

To maximize efficiency, prevent breakdowns, and extend the life of your water heater, follow these essential maintenance tips:

1. Perform Periodic Inspections: Inspect your water heater every few months for signs of wear, leakage, or corrosion. This proactive measure can help you catch any potential issues early on and avoid costly repairs.

2. Drain and Flush the Tank: For traditional tank-style water heaters, draining and flushing the tank at least once a year removes sediment buildup, which can cause inefficiencies and reduce the unit’s lifespan. Turn off the power and water supply to your unit, connect a hose to the drain valve, and flush the tank until the discharged water runs clear.

3. Test the Temperature and Pressure Relief Valve: Regularly testing the temperature and pressure relief (TPR) valve helps ensure that it’s functioning correctly and prevents potential hazards. To test the valve, lift the lever and then let it snap back into place, checking for smooth operation and proper water flow.

4. Insulate the Tank and Pipes: Insulating your water heater tank and pipes can improve energy efficiency by reducing heat loss. Use specialized water heater blankets and pipe insulation to maximize the effectiveness of these improvements.

5. Adjust the Temperature Setting: Lowering your water heater’s temperature setting to 120°F can save energy, reduce scalding risks, and prevent sediment buildup. Adjust as necessary to find the ideal balance of comfort and efficiency.

Tankless Water Heater Maintenance

While many of the tips above apply to both tank-style and tankless water heaters, the latter has some unique maintenance requirements:

1. Regular Descaling: For tankless units, heat exchanger scaling can reduce efficiency and lead to malfunctions. Depending on water hardness and usage, descaling should be performed annually or as needed, using a specialized descaling solution to dissolve mineral buildup.

2. Clean the Inlet Screen Filter: Tankless water heaters feature an inlet screen filter that prevents debris from entering the unit. Regularly cleaning this filter can help maintain optimal performance and prevent flow restriction issues.

The Necessity of Professional Maintenance

Though performing routine maintenance tasks on your own can help extend the life of your water heater, professional assistance is crucial for the optimal function and safety of your unit. Here’s why:

1. Expertise: Licensed plumbing professionals, like the team at John’s Plumbing & Drain Services, have the training and experience to accurately diagnose any potential issues with your water heater, ensuring comprehensive maintenance and repair services.

2. Specialized Equipment: Professional plumbers have access to tools and equipment that aid in detecting potential problems and performing maintenance tasks efficiently and effectively.

3. Safety: Working with water heaters involves handling high temperatures, pressures, and electrical components, all of which can pose safety risks if improperly managed. By enlisting professional help, you can ensure that maintenance tasks are performed correctly and safely.

Signs It’s Time for Repairs or Replacement

While regular maintenance can prolong your water heater’s life, it’s essential to recognize when it’s time for repairs or a new unit. Some indicators include:

1. Age: Traditional tank-style water heaters typically last 8-12 years, while tankless models can last up to 20 years. If your unit is reaching the end of its expected lifespan, consider an upgrade to a more energy-efficient model.

2. Inconsistent Temperatures: If your water heater is only providing intermittently hot or lukewarm water, it may be time for repairs or a new unit.

3. Leaks: Water pooling around your water heater often indicates a serious problem that may require a repair or replacement.

Final Thoughts

Proper water heater maintenance is essential for ensuring the efficiency, reliability, and longevity of your unit, whether in a residential or commercial setting. By following the essential maintenance tips highlighted above and enlisting professional plumbing assistance, you can rest assured that your water heater will provide the hot water you need for years to come.

Our water heater began spewing water this morning.  John was the first plumber in the area to answer my call, and was able to get to my house within 10 minutes of the call.  He fixed the problem promptly and for what seemed to be a reasonable price.  He was friendly and informative.  I will definitely call John again and will recommend him to neighbors.  Thanks, John!

John has done numerous plumbing projects around my house and has always done excellent work.  He's quick to respond to my inquiry's and even replaced my water heater on a Sunday.  Most recently, I had him install a water purification system and new faucet.  His prices are reasonable and he will continue to be my go-to plumber.

Project: Install, Repair or Replace Plumbing or Fixtures

Comments: I am very pleased. I've had John do the top priority job of repairing a leaking drainpipe and his work looks to be top notch. I'm definitely thinking of using him for the larger job of repiping the whole house (replacing the failing M-type copper with L-type). And again, John's bid is within my budget considerations. Highly recommended.

Camera Locate Breakage for a Plumbing System

Comments: We had them run a snake from our sewer line out to the street, as we have lots of trees with roots that sometimes get into the line. They came as scheduled, did a great job and the price was as quoted.
