Water Heater
There are a number of different reasons you might notice rust spots on your water heater tank. Most importantly, this is a sign that the inside surface of your water heater tank has begun to deteriorate. This can be caused by hard water, low PH levels, mineral build up, or even age. Whatever the cause, this deterioration will cause your water to be discolored and can damage your plumbing. Fortunately, if you notice this, it’s often still possible to repair your Phoenix water heater.
A Phoenix water heater repair tank is made out of metal that is susceptible to corrosion, especially if it has been exposed to flooding and standing water for extended periods of time. In order to keep this from happening, a water heater tank is designed with an airtight seal that keeps out oxygen necessary for the chemical reaction that creates rust.
In addition, most tank water heaters have a glass interior that protects the steel from direct contact. Another important defense is a sacrificial anode rod that runs through the center of the tank. The rod is designed to rust so that the rest of the tank doesn’t. While the scientific explanation for this is complex, the simple explanation is that the sacrificial rod attracts the corrosive elements that would otherwise rust the tank.
Can a Water Heater With a Rusty Tank Be Repaired?
The problem is that when the anode rod corrodes, it leaves the steel tank vulnerable to rust. This is why it’s important to inspect and replace your anode rod as needed to help prevent rust from building up in your tank. This is typically a part of a regular water heater maintenance service that includes draining and flushing the water heater tank to remove sediment.
If the rust has spread far enough to cause the water to be a brown color, this is usually an indication that there is more serious problems with your hot water heater. This is a good reason to call your plumber to schedule an appointment right away, as this is often a sign of a leak or a dangerous issue that can lead to further problems like flooding and water damage.
While rusty water can stain fixtures, give a metallic taste, and leave stains on clothing and skin, the U.S. Environmental Protection Agency deems it safe for use. However, it is still not ideal and can cause discomfort for your family. If you’ve noticed rusty water coming from your home’s water heater, it’s a good idea to call for a Phoenix water heater repair as soon as possible to prevent inconvenient stains and to help your hot water last longer. A professional plumber will be able to determine whether the rust is fixable or if your water heater will need to be replaced. This can save you money in the long run by avoiding more expensive repairs in the future. A qualified plumber will also be able to provide advice about other preventative measures you can take, such as installing a water softener or undergoing routine maintenance.
