Protecting Your Water Heater: How to Preventing Scale and Corrosion

January 9, 2024

A water heater is a crucial appliance in any household, providing hot water for various daily activities. However, over time, water heaters can fall victim to scale and corrosion, leading to reduced efficiency, increased energy consumption, and ultimately, system failure. In this article, we’ll explore the causes of scale and corrosion in water heaters and provide a comprehensive checklist to help you prevent these issues and extend the life of your water heater.

Understanding Scale and Corrosion:

Scale: Scale is the accumulation of minerals, primarily calcium and magnesium, that form a hard, insulating layer on the inside of the water heater tank. This layer reduces the heat transfer efficiency, forcing the heater to work harder to maintain water temperature.

Corrosion: Corrosion occurs when the metal components of the water heater, such as the tank or heating elements, react with oxygen and water to form rust. Corrosion weakens the structural integrity of the water heater and can lead to leaks or even complete system failure.

Preventive Measures: Checklist for Water Heater Maintenance:

  1. Water Softening:

Install a water softener to reduce the hardness of the water.

Regularly check and replenish water softener salt levels.

  1. Anode Rod Inspection:

Inspect the sacrificial anode rod annually.

Replace the anode rod if it is significantly corroded or less than half its original size.

  1. Temperature Setting:

Set the water heater temperature to a safe and efficient level (typically around 120 degrees Fahrenheit or 49 degrees Celsius).

  1. Flush the Tank:

Drain and flush the water heater tank annually to remove sediment and prevent scale buildup. 

Follow the manufacturer’s instructions for proper flushing.

Pressure Relief Valve:

Test the pressure relief valve periodically to ensure it is functioning correctly.

Replace the valve if it is leaking or not operating as intended.

Regular Inspections:

Conduct visual inspections of the water heater for signs of rust or corrosion.

Check for leaks around fittings and connections.

Water hardness Testing:

Periodically test the water quality to ensure it meets recommended standards.

Consider installing a water filter if necessary. Поставить фото (цвет

Regular Maintenance:

Follow the manufacturer’s maintenance guidelines.

Inspect and clean the heating elements if applicable.

Install a Water Softening Device:

Consider installing a water softening device to reduce mineral deposits.

Choose a device that suits your water hardness level. Read more here!

Professional Inspection:

Schedule a professional inspection of your water heater at least once every two years.

Hire a qualified technician to assess the overall condition and performance of the system.

By taking proactive measures and following a comprehensive checklist for water heater maintenance, you can significantly reduce the risk of scale and corrosion, ensuring the longevity and efficient operation of your water heating system. Regular inspections, proper temperature settings, and addressing issues promptly are key to preventing costly repairs and replacements in the long run. Remember, a well-maintained water heater not only saves you money but also contributes to a more sustainable and energy-efficient home.

Bella is very knowledgeable about tankless water heaters. She determined that the heater that I purchased from Amazon was the wrong model. She went above and beyond the call of duty. She drove me in her car to the UPS store so I can return the heater and then drove me to the supplier store in San Jose (Pace Supply) so I can buy the correct one. She is very honest and showed me the wholesale price of the heater and used her coupon to get me the wholesale price. Umed, the technician, is an expert and did a great job installing the unit. He arrived on time, was very polite, and cleaned the area after his work was done. Bella and Umed put the customer first and provided an excellent service. I highly recommend United Plumbing because of Bella and Umed, their honesty, great service and expertise.

Technician Beck came on thanksgiving day, working from 3pm till almost 9pm, to replace a new water heater. In the middle of the installment, he even had to go back to his office and pick up new parts. It was very difficult to set up the tubes at my place since the space for the tubes/water heater was limited. Technician was very patient and friendly the whole time. The pipes after Beck’s work are better designed. I am very grateful they are willing to come on a big holiday like thanksgiving, getting the challenging work done without any complaints. Otherwise it would be a cold shower thanksgiving for us. Highly recommend.
United was quick to do an inspection and quote to replace our 20 year old tank water heater for a tankless and was able to start the job the same day. Professional and great service and the price was the lowest I received out of 3 or 4. Highly recommend!
Quality work. Respectful of the property, and clean. Showed up on time. Alex gave good advice, answered numerous questions and only charged for the work performed per agreement. We will call them again.

Yuri was great! Yuri came to inspect the pipes that were hearing while the water is running but unfortunately we weren’t able to hear anything at the time of the inspection. Yuri was able to install a new faucet in my kids bathroom. If you are looking for a plumbing company use United Plumbing, from the office to the field the service was great! I will definitely use Yuri and United plumbing again in the future.
