Where are Pete's Plug® connections positioned in a system?

The correct answer emphasizes the strategic placement of Pete's Plug® connections to facilitate future maintenance or monitoring needs within a system. By positioning the connections where future readings may be required, technicians and engineers can efficiently access and assess system performance or conduct troubleshooting without significant disruption. This foresight ensures that necessary connections are readily available for potential tests or adjustments in the future, enhancing the overall functionality and serviceability of the system.

In contrast, positioning the connections at the highest point, solely on pump outlets, or adjacent to the main supply line may not adequately address the need for future accessibility for readings. These alternative locations could limit the ability to gather critical data or perform maintenance when required. The focus on accessibility and functionality in option B makes it the most practical choice for effective system management.
