What is the benefit of knowing about ambient water temperature before installation?

Understanding ambient water temperature before installation is crucial for ensuring proper material selection. Different materials can react differently to varying temperatures; for example, certain plastics may become brittle or flexible at specific temperatures. By knowing the ambient water temperature, a technician can choose materials that will withstand those conditions and maintain the integrity of the system over time. This knowledge helps prevent issues like expansion or contraction that can lead to leaks or other failures.

In contrast, while water pressure, flow calculations, and chemical reactions are also essential factors in system installation, they don't directly relate to the selection of materials based on temperature. Water pressure may depend more on system design and existing infrastructure, calculating flow involves other parameters, and assessing chemical reactions usually pertains to the interaction of water with contaminants or substances rather than the effects of temperature on material stability.
