We have a customer whose pre-action system for a library is impaired due to electrical/ detection problems. He has had a contractor trip it into a wet pipe system. We are looking for a code reference prohibiting this kind of "repair". Is this possibly just an AHJ decision? Any suggestions?

We have approved high pressure steel braided rubber hose for these situations often, as long as they installation is such that the hose remain submerged. Not a whole lot of better options that we are aware of at this point.
