Have a sprinkler system in house my wife and I are remodeling, system installed in 1993 and is no longer in production, need to modify but pro said can't be done without redoing system...it is a thin walled metal pipe inserts into a fitting with an o- ring and a clip holds in place. Any know the system? Parts?
Is it an actual fire sprinkler company? Not a plumber? Time for 2nd and 3rd opinion either way. See members of www.NFSA.org . I know of no reason why a previously approved system has to be removed because of the piping.
