Test & Drain with ESFR K25.
Should 3/4 ESFR T&D be installed with ESFR K25 sprinklers. As per my online research it seems like yes.
I haven't found this information - yet - clearly anywhere in NFPA. I believe a lot of the jobs simply install 5.6K T&D for all sprinkler jobs.
Can someone link me to the proper way. Can I simply install a 5.6K T&D. It seems hard to find a 3/4 ESFR or a 17/32 as nobody seems to really offer them nor stock them.
Can you refer me to further information about this. Thank you,
