Which condition must be met for water temperature in resident facilities?

The requirement for water temperature in residential facilities emphasizes the need for comfort for residents. This means that while specific temperature thresholds may be relevant, the overarching consideration is that the water must be at a temperature that residents find pleasant and usable. Comfort can vary among individuals, making it essential that facilities allow for adjustments in temperature to meet the needs and preferences of various residents.

While there may be guidelines or recommendations regarding maximum temperatures for safety reasons—like avoiding burns from hot water—ensuring that the water is comfortable is a broader standard that can encompass individual preferences and needs. Additionally, the mention of specific temperature limitations may not fully capture the essence of resident comfort, which prioritizes adapting to what is suitable for the environment and the people living within it.

The other options may reference safety standards or practices but do not capture the focus on residents' comfort as a primary requirement for water in residential settings.
