1/2 copper piping in scheduled system c/w images
(OP)
Hello
I've been browzing the books and it seems to me there was once mention about the use (or restrictions) of 1/2" copper. I've uploaded a couple of photo's to http://www.flickr.com/photos/9995775@N05/?saved=1
pics DSC01204 and 05.
References and thoughts appreciated.
Regards
Dave

14.4.1.2 Pipe sizes shall be no less than 1 in. (25.4 mm) nominal for ferrous piping and ¾ in. (19 mm) nominal for copper tubing or nonmetallic piping listed for fire sprinkler service.
¾" steel pipe was allowed to be used into the 1930's (I think it was the 1939's)
Obviously this work was accomplished without calculations by plumbers.

Now there may be a problem if remodeling

The max length of 1/2" pipe is 4 inches, it appears the length is more then 4 inches. Most likely a plumber did the install not a sprinkler contractor....

Was this at an amusement park by chance??
Hate to ask the question, but do you know if was required when installed??
RE: 1/2 copper piping in scheduled system c/w images
Installed circa 1974. Amusing but no, not at an amusement park. Yes it was required, probably much to the chagrin of the owner(s) who then decided to farm the work out to whomever would do it cheapest, and in those days it was quite common for plumbers to take on the work, as a sprinkler contractor would have had to come up from down south. And quite frankly, this situation is not uncommon. Nor is the fact that nothing will probably be done about this type of thing until the rules for grandfathering are clarified.
