We manufacture dust collectors and pre-pipe fire sprinklers within them with a couple fusible fittings.
We pressure test the pipe at our shop, however, when a contractor connects to them in the field, are there any code/standard requirements to check the system for leaks after connecting to the system?
We put on our drawings that the contractor should test for leaks, however, we're trying to determine what requirements exist for this application.
The problem we're running into is that the connection is supposed to be made and checked before installing cartridges. If a leak occurs, the contractor could address and not get the paper cartridges all wet with running water down at the floor. In this last case they didn't, and I'm trying to address future installation of systems and make sure the contractor checks for leaks.
