You can often times pay for larger pipe easier than paying for K25's. You just have to run the numbers both ways to make the right decision. There are usually several things to factor into the process. Pipe, fittings, hangers, LABOR, etc. Have fun!

However the K25 are about 3 times as much as the K16.8....

It is odd that 32' is the only height that only offers two choices where all the others offer four choices. But both the Handbook and FMDS 2-2 have some comments related to the selection of sprinklers. If you did not have 40-60psi to use for the system and a k...@20 psi for instance lists its use as applicable to your conditions I can't see any reason why you could not use a K-25 ESFR sprinkler. But understand that a plan reviewer may not accept your alternative since it's not listed on the chart. Per the NFPA 13 Handbook: "The criteria in Table 16.2.3.1 have been expanded to permit broader applications of ESFR sprinkler technology based on large-scale test results reviewed by the Technical Committee on Sprinkler System Discharge Criteria." FMDS 2-2 The K14.0 (K200) pendent, being the original suppression mode sprinkler, has the widest array of applications. Do not assume that other suppression mode sprinklers can be used for applications where the K14.0 (K200) pendent sprinkler is permitted. Craig L.

Per the table I'm given the choice of either 14.0k or 16.8k, am I limited to these two options or can I use any "K" as long as the data sheets support it? Also, If it helps the calc's can you go up a level to the 35ft ceiling row and use those heads? Thanks!
