Good morning Ladies/Gentlemen: I do not know where < 20 sprinklers might be found in 25 (or any other standard) and/or why there would be such a stipulation in the first place...That said: IF an overwhelming number of failures attributed to sprinkler systems (all sizes) are due to closed valves and/or inadequate water supplies, it seems 'logical' that, if a sprinkler system has a water supply and/or control valve, those devices would need to be check/tested/inspected, regardless of the number of sprinklers in the system?? The number '20' has been bandied around for years as to adding that number of heads to an existing system, plans submittals, whether a hydro was required, FDC requirement, etc. In my professional (albeit humble) opinion, ALL fire sprinkler systems need to be inspected/tested per NFPA-25 guidelines. I rather suspect our friends in the insurance industry would concur. In New Mexico, it is quarterly - it is statewide (commercial systems).

In Seattle the rule was, and may still be but I haven't worked in industry for some time, that a six head or less T.I. didn't require an inspection, but that was local to Seattle.
