None of that information was made available to us. It isn't super close to the Supply as the Racking is in the Middle of the Store and the Fire Riser/Pump Room is on the far corner of the store on the outside of the building. ________________________________ From: [email protected] <[email protected]> Sent: Wednesday, March 15, 2023 11:19 AM To: [email protected] <[email protected]> Subject: [Sprinklerforum] Re: Fire Sprinklers in Racking
[EXTERNAL SENDER - USE CAUTION] Technically, most changes require evaluation. Racks must be balanced with the overhead. Is it closer to the supply? Is the common connection point providing less than .5psi balance? There are many factors at play with this.

Got called out to a Home Improvement Store who had their Paint Racks moved and when they did they had the Piping in the Racks removed by a Company however this Company did not return to put the piping back in thus my company being called out to fix the issue. When we started to evaluate the situation we were told that the Racking Size had not changed and the Hazard had not either however once we started the job and got to the point where the Piping that was removed be put back in we found that the Rack Size was different and the piping set up was not correct for the length. Rack Length: 54' 9" Total Pipe Network: 55' 10" Sprinkler Heads 50" apart The Piping Network was all Pre-Fab welded Pipe. Question is with the change is setup does the Sprinkler System need to be looked at by an Engineer and have plans drawn up or can this all be done without going to that length? Does it need to be Re-Calculated?
