What is the proper point in a system to take the antifreeze sample?
I have taken readings at both outlets at the check valve, unfortunately a contractor is saying to take it at the most remote point. Those locations are either 25-feet in the air, or not installed at all.
Thanks in advance.

You are both correct per NFPA 25 - 23' Edition

A similar prescriptive requirement for the “test connection(s)” for “Antifreeze systems” is referenced in “2022 NFPA 13 — Standard for the Installation of Sprinkler Systems” which references “2020 NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems.”
