Are there any drawbacks of testing a diesel-engine fire pump on a main header where other diesel pumps are connected to, instead of a test header?
This is happening in my plant because the test header is is large enough that it would require frequent throttling of test header discharge gate valves for each pump, which has started to wear out and not hold pressure.
Also, what is the minimum flow requirement for weekly diesel pump testing considering the test header doesn't hold? Do we need to run 0%, 100%, and 150% flow test each week?
