Subject: Re: Pre-.05 density heads: What heads can be used as a replacement ?
Thanks Art and Mike-I have done so but they are just as lost as I. It seems the
only solution is to do a complete re-calc of the existing system. The problem
is that in those days, especially here in Florida, the sizes used are not the
sizes you see today. Back then, all of the lines were ¾" and the mains were
either 1" or 1-1/4". Sadly, not most foresight was given to what to do when
these heads had to be replaced.
Globe is the only manufacturer that still produces replacement residential
sprinklers. Reliable, Viking, Tyco, etc... all phased them out back in
2004/2005. In addition, none of the manufacturers are willing to put their
"professional opinions" on paper which is understandable due to the liability
it would entail so that is why I am relying so much on hopefully NFPA, NFSA,
AFSA, etc... addressing this somehow.....
Most local AHJ's would just as soon require them to be calculated but most
contractors will not release old installation plans (if they still have them)
and many local AHJ's do not keep records going back that far....
