Which type of water is defined as having a temperature range between 85°F and 110°F?

Tempered water is defined specifically by the International Plumbing Code as water that is maintained at a temperature range between 85°F and 110°F. This temperature range is significant because it is designed to be comfortable and safe for various uses, particularly in applications such as handwashing, where temperatures that are too high can cause burns, and temperatures that are too low may not be effective for cleaning.

Understanding the concept of tempered water is essential in plumbing practices, particularly concerning water heating systems and installations for domestic use. It allows safe and effective water usage while maintaining compliance with health and safety standards. The other types of water mentioned have different temperature ranges, which do not align with the recognized definition of tempered water.
