When surveying domestic water points of building entry, which of the following should not be recorded?

When surveying domestic water points at building entry, it is essential to gather relevant data that can impact the growth of Legionella and other potential contaminants in the water system. Recording temperature measurements, water pressure, and flow rate helps assess the system's adequacy for maintaining safe water conditions.

Temperature measurements are critical because Legionella thrives in warm water, particularly between 77°F and 113°F (25°C and 45°C). Monitoring the temperature can identify areas where temperatures are conducive to bacterial growth.

Water pressure is an important factor in maintaining the overall functionality of the plumbing system. Low water pressure may indicate issues with the plumbing that could affect water quality and safety.

Flow rate is equally significant as it can provide insights into the performance of the water delivery system and help identify potential stagnation areas where water may sit and become conducive to bacterial growth.

In contrast, while alkalinity may influence water quality and facility operations, it is typically not a primary parameter for assessing immediate risks associated with Legionella in the context of plumbing surveys. Alkalinity measurements are more relevant to water treatment and chemical balance but do not directly provide insights that would inform Legionella risk management strategies in the same critical way as temperature, pressure, and flow rate do.
