Our building code allows the pressure be lower if the building is sprinklered and you do not require a fire pump to get the sprinkler system to work, no minimum pressure is specified.
If a fire pump is required then you must meet the minimum of 100 psi as per NFPA #14 Thank you James Crawford Phaser Fire Protection Ltd.

For the forum community "what is the minimum design pressure required for a new class I automatic wet standpipe in your location?" I know what the un-amended code says, but it includes the catch-all qualification about the AHJ being consulted for specific needs. So what I'm looking for is, in your region/area; 1- Does the local fire code accept the NFPA14 requirement for 100 psi minimum operating pressure at the required flow rate? 2 - Does the local fire code amend the NFPA14 requirement from 100 psi to something higher or lower? 3 - Does the local Fire Code Official regulate the NFPA14 requirements without having amended the current fire code, ie, require a higher or lower pressure than the written code? Also, from the NFPA 14 committee, any comments on discussions leading up to the change from 65psi to 100 psi, and your thoughts on the matter will be appreciated. In addition, related comments from the Fire Fighters among us, on actual experience in the "heat of the battle", are most welcome. And lastly, in respect of the Forum Traffic Control officials, please respond to me directly "off forum" at mphe...@aerofire.com<mailto:mphe...@aerofire.com>.
