Hello Matt I was working in a data center where the customer was very hydrophobic so we decided to use the "dry" flex pendants. They worked very well and in case of an accidental dump of the system their would be no trapped water.

I was thinking about using flex drops in the drop portion of the return bend for ease of testing and center of tile. The flex drops are listed for use in dry systems - so I can't think of any code reason not to do it. Has anyone used flex drops in pre-action or dry systems before? Any issues?
