Most places defer the jurisdiction to the AG departments. My health inspector was here yesterday and he confirmed that for me also.
Most brewing equipment falls under the Dairy 3-A program. All the triclamps and such are sourced from dairy so it the health department covers dairy in your area then I think they would have the call on it. I expect that they do not though. If you are a brewpub then there is a point in the process where they take over. I believe it is at the connection to the tank unless alcohol is covered by your ABC board.
Just my thoughts....
