Looking for guidance on pressure gauge selection. Is there a requirement for a maximum pressure gauge for testing residual pressures of 40-50 psi on suppression systems?
Wondering if any pressure gauge is adequate or if there's specific guidance I should be following on gauge selection. Posted anonymously for discussion. Discuss This | Submit Your Question | Subscribe

When testing a fire pump from the roof is there a calculation that is necessary to ensure that the flow test is accurate (given pipe sizes, elevation increase, etc)?
NFPA 25, 2014 handbook states that flowing from the roof in the explanatory material is somewhat acceptable (NFPA 25, 2014: 8.3.3.1.3). However, NFPA 20, 2013 A.4.20.3.4(2) has a sample hydraulic calculation sheet for sizing the test header when not using the table which appears to take into account items like friction loss, elevation, etc. Posted anonymously for discussion.
