Ron, Nope, it’s designed that way. I’ve asked fitters to look, and I’ve looked at new ones off the truck. That’s the way it comes. Data sheet doesn’t show it, or say anything about it.
Nope. I’m thinking most don’t realize this, and most don’t realize wiping off the seat pushes the gunk into the slot that leads to the two holes.

Nothing about that in the cut sheet and that would be some neon flashing sign if there was a special tee in the alarm line. Have you talked to Tyco? As an example of this Viking has special ball drips that work only on designated valve trims. One that will not work with a DPV may be for a deluge valve.The info for this is glaring when you actually go looking for it. http://www.vikinggroupinc.com/databook/checkvalves/062289.pdf
