What is checked last during a flow test?

In the context of conducting a flow test, the last aspect checked is typically leaks. This is because ensuring that the system is functioning properly and delivers the required flow is prioritized first. Only after confirming that the system is capable of maintaining pressure levels, providing sufficient capacity, and draining at the correct speed is it prudent to examine for leaks.

Checking for leaks last is essential because it allows for a complete assessment of system performance under operational conditions. If issues are discovered early in the testing process regarding pressure levels, system capacity, or drainage speed, they may need to be resolved before a thorough leak inspection is warranted. Thus, performing the leak check at the end ensures that all other conditions are stable and helps in identifying any issues specifically related to the integrity of the system after it has been fully tested.
