As well as water supply, size of combined test connection, all for simultaneous operation.
From: Eric Rieve <[email protected]> Sent: Monday, January 29, 2024 12:17 PM To: Discussion list on issues relating to automatic fire sprinklers <[email protected]> Subject: [Sprinklerforum] Re: Fire Pump testing procedures NFPA 25 added a section regarding this in 2023. 8.3.3.11: Where simultaneous operation of multiple pumps is required to meet the water-based system demand for flow and pressure, the requirements of 8.3.3.10(2) shall be repeated at each flow condition with all pumps operating simultaneously. So, your test-header will need to accommodate the combined flow. Hope this helps!

Individually to find out that each pump is working correctly itself and both to verify that the full demand can be met. For a future testing program, probably something specialized would be needed. Make sure it is available in writing.

Client doesn’t want any pumps over 1500 gpm. Long story. As far as testing, would you test each pump individually or together or ?? Trying to establish what we need as far as a test header. Thanks.
