This was the Tyco Dry valves specifically listed for low pressure (monitoring pressure) and required a 15 second water delivery time. The residential sprinkler listing were updated to include dry systems. After checking, I don’t see this on their website anymore so it may have been discontinued.

Ive only ever seen standards and manufacturers documentation saying that CPVC products are approved for wet systems only. Maybe instead of telling him no, you can ask client to produce the documentation saying it is acceptable – we can do whatever the client wants as long as it complies with codes, standards, manufacturer’s docs, and AHJ approval. That way you don’t have to risk being wrong, while maintaining compliance based on your own knowledge.

I have never heard of it and can’t find any references about it. Before I tell him no, is there something that I am missing?
