If pre-1993 plumbing fixtures are still in place (i.e. the bowls), but their flush valves have been replaced post-1993, does that count as 'plumbing renovation' / fixture replacement for the purposes of the pre-req/credit?
Hi Michael,
Sounds like this would not count as a "plumbing rennovation", so you could still list those fixtures as pre-1993. Per p. 85 of the Reference Guide, my take is that a flushometer change out is considered a minor retrofit, and doesn't trigger the more stringent baseline.
