How frequently should the working pressure in a gas system be monitored?

Monitoring the working pressure in a gas system regularly, especially when there are changes in usage or pressure, is crucial for safety and efficiency. Regular checks help ensure that gas appliances are operating within the safe pressure range and that there are no leaks or pressure drops that could cause malfunctions or hazardous situations. Changes in usage, such as the addition of new appliances or alterations in consumption patterns, can significantly affect the system's pressure balance and, therefore, warrant more frequent monitoring. This proactive approach not only helps in identifying issues early but also contributes to the overall reliability of the gas system and the safety of its operation.

In contrast, monitoring pressure only once a year or every five years may lead to undetected issues that could escalate, while checking the pressure solely during the installation of new appliances misses important ongoing operational needs.
