Corrosion is the process by which metal deteriorates due to chemical reactions with its environment. In the context of water heaters, this can cause damage, reduce efficiency, and ultimately lead to the need for extensive water heater repair in Wheaton, IL. Our experts at Keeley’s Plumbing discuss some of the most common causes of corrosion on water heaters and how to prevent it.
Hard Water
Hard water contains high levels of minerals such as calcium and magnesium, which can accumulate over time as sediment within the tank. This can create an insulating barrier between the water and the heating element, causing it to overheat and corrode.
Wheaton water, in particular, has a hardness of 6 to 8 grains per gallon, which falls under the moderately hard category. It’s essential to regularly flush your water heater to remove any built-up sediment and avoid needing new water heater installation.
Low pH Levels
Water with low pH levels is acidic and can cause corrosion to occur at a faster rate. The average pH level for water is between 6.5 to 8.5, with any value lower than 7 considered acidic. If your water heater is constantly exposed to acidic water, the metal components can start to deteriorate and eventually fail, potentially leading to leaks and even water heater replacement. To prevent this issue, test the pH levels of your water and install a neutralizing filter if necessary.
Anode Rod Deterioration
The sacrificial anode is a crucial component in most water heaters that helps prevent corrosion by attracting the corrosive elements present in water. Over time, this rod can become depleted and result in accelerated corrosion of the tank. Let an expert in water heater services regularly check and replace the anode rod to prolong the lifespan of your appliance.
Corrosion can occur in a tankless water heater as well, making it essential to regularly schedule maintenance and flushing. Whichever type of water heater you have, however, Keeley’s Plumbing can help keep it running smoothly with effective upkeep and repairs. Contact us today to schedule an appointment.
