During freezing weather, how often must the temperature of water inside the gravity tank be checked?

Monitoring the temperature of water inside a gravity tank during freezing weather is crucial to prevent the water from freezing and potentially damaging the system. Checking the temperature daily is considered an appropriate safety measure. This frequency ensures that any drop in temperature can be detected and addressed promptly, allowing for timely interventions such as heating the tank or taking other measures to prevent freezing.

In the context of freezing weather, a daily check strikes a balance between operational practicality and the urgency of preventing system failures. Performing this check less frequently, such as weekly or monthly, may not allow for quick enough actions to mitigate the risks associated with low temperatures, hence could lead to significant problems if the temperature drops unexpectedly. Therefore, the recommendation for regular daily monitoring provides a proactive approach to maintaining the integrity of the standpipe system in cold weather conditions.
