NFPA 25 '11 3.3.4 Deficiency. For the purposes of Inspection, Testing and Maintenance of water-based fire protection systems, a condition in which a system or portion thereof is damaged, inoperable, or in need of service, but does not rise to the level of an impairment.
Given that the floor drain is not part of the "system or portion thereof" my answer (at least to our service sales reps/inspectors) would be a resounding no. If NFPA 25 doesn't specifically call for an inspection of floor drains (I have yet to find the section if it does), it doesn't go on an NFPA 25 deficiency report.
If the main drain itself (the portion thereof) works, it SHALL be tested (13.2.5). If it is not tested, this will be because the owner says no. Get his signature! 25-'11 4.1.1: The property owner or designated representative shall be responsible for properly maintaining a water-based fire protection system.
Note on your report that a main drain test was not performed, why it was not performed, and who forbade it from being performed (signature!!). Once you turn the report in to the fire dept., let them deal with enforcement.
Long story short, I do not believe that an inadequete floor drain is a sprinkler system deficiency, and therefore should not show up on a sprinkler system deficiency report.
Fair warning: I might be a bit biased on this issue. We had a system recently written up by the competition for this exact problem. We raised our collective palms and said, how is it our problem if you haven't cleaned your pea traps in years?
Re: the RPZ. Again, careful. NFPA 25 doesn't say, inspect them when it's easy or convenient, it says you SHALL inspect them. If they're 26' AFF in a grocery store, I see your point (seen enough of them installed like that too). Chances are you didn't included for a scissor lift in your annual inspection quotation. Tough call, but one that needs to be addressed nevertheless. Not an NFPA 25 to my knowledge.
Talking about test cocks, correct me if I'm wrong (I very well may be), but nothing in NFPA 25 (or 13 for that matter) requires hooking something up to a 1/4" tap. NFPA 25 stipulates that the device be inspected to determine:
-the valves are open (13.6.1.1)
-The RP isn't continously dumping (13.6.1.2)
-a forward full flow test is performed (13.6.2.1.1)
Testing backflows to see if they can indeed prevent backwards flow is required by the city's cross-connection department (speaking for sask only) and is not an NFPA 25 requirement.
