Scale is a hard residue, made up of minerals such as calcium and magnesium, that forms inside pipes and other plumbing fixtures. Scale formation occurs when minerals precipitate out of the water and stick to the inner surfaces of the pipes, fixtures, and appliances. This process is more likely to happen when the water has a high concentration of these minerals. Over time, scale builds up limiting the amount of water that can flow through the pipes, leading to reduced water pressure and potential damage to the plumbing system.

What can I do if I have scale buildup in my water system?

One common approach is to use acid to remove the scale, especially in the drop pipe for a well. Another option is to use mechanical methods, depending on the type of scale and its friability. For example, spinning devices or tools can be used to break up the scale. It’s important to consult with a professional well contractor who specializes in addressing scale buildup to determine the most suitable method for your specific situation.

It is important to monitor TDS levels in water and take appropriate measures to prevent excessive scale buildup, such as using water softeners or descaling treatments. For more information on treatment options, contact a water treatment professional - we would recommend contacting one who has been certified through the Water Quality Association’s Professional Certification Program.
