How to Prevent Scale Buildup

Ever wondered why your plumbing clogs or your appliances wear out quickly?

 Scale buildup could be the culprit. Scale buildup refers to the accumulation of minerals, primarily calcium and magnesium, in water pipes and appliances. This process happens when hard water, which is high in mineral content, flows through your plumbing system, leaving behind these mineral deposits.

But what causes this pesky problem? 

The main reason is hard water. When water has a high concentration of dissolved minerals, it is considered hard. As this water moves through your home’s plumbing, it leaves behind traces of these minerals. Over time, these traces build up, forming a hard, chalky substance known as scale.


Why Arizona is Prone to Scale Buildup

Water Hardness in Arizona

Why is scale buildup particularly common in Arizona? 

The answer lies in the nature of the water itself. Arizona’s water is among the hardest in the United States. Hard water contains high levels of dissolved minerals, primarily calcium and magnesium.
