Might be worth at least a spot check. The end of dead end branch lines can
hold
compressed air (equal to the water pressure) and could create the same
situation. Probably not as severe as a dry system, but the potential is
there.
There is also the potential for other obstruction issues beyond rust (MIC,
etc)
that could be an issue.
NFPA 25 (2008) for obstruction investigations does not differentiate
between wet
and dry systems.

We have removed the end of line fittings on dry systems and found rust and
other
foreign material. We have then flushed the lines. Is there also a need to
remove
end of line fittings on wet systems?
