Hygroscopic materials have the ability to attract or absorb moisture from the air. In plumbing, this property is significant for materials like certain salts, desiccants, or gaskets that can absorb ambient moisture, affecting their performance or longevity. For example, hygroscopic desiccants are used in dryers and dehumidifiers to remove moisture from the air, protecting plumbing systems from condensation and preventing corrosion. Hygroscopic materials must be carefully stored and maintained, as they can change in size, shape, or effectiveness when exposed to high humidity. Understanding the hygroscopic nature of certain materials helps in selecting appropriate components for plumbing systems, particularly in environments with varying humidity levels.
