We tried out something new a couple months ago with a Detail Pick-Apart covering a dry sidewall sprinkler at a deck. We had a great response - healthy discussion from a wide variety of perspectives. Way back when we even talked about different parts and purposes for components of a wet riser. It's the dialogue that I often find the most helpful in seeing and understanding perspective that I simply just don't have. No detail is perfect, nor is it applicable in all situations. No way. It's one possible solution to some situations. That said, it can be really helpful to have open discord and learn from it. Quick rehash on ideas for critique and discord: USE CASES: What are good use cases for this? PROS: What benefits does an approach like this bring? CONS: What are the negatives with an approach like this? IMPROVE: What ways can this approach be improved? What critique would you offer here?
Thanks, as always, for being part of making the industry better.

Just the nuts and bolts of it, very nice. I assume the premise of this is to have a universal detail that can be tailored to any shotgun riser assembly.

From a practical perspective, It's rare to have a lead-in match the riser size. Typically the riser is smaller (and can provide a lot of cost savings by being smaller), so a reducer below the backflow would be indicative of a more common riser install. BUT then you go down the road of what will the water department allow before the backflow? Does it need to be cement lined? Can it be a painted grooved reducer? Galvanized? The galvanized pipe below the backflow is a no-no with many water departments.

Following up on others especially Casey’s excellent comments, I do declare. A few thoughts off the top of my head. I wish I could edit this as I think of more. Interested in further discussion:

Domestic water takeoff for combined service was going to be my suggestion as well. Reduced Pressure drain from backflow is a big deal and make this substantially more complicated. Water providers are demanding RP because more is better. The forward flow valves in our area are piped to the exterior (similar to an FDC) instead of hoses through a door. Show the FDC connection. Ours is typically ahead of the water flow switch.

Ever so minor, but the T&D looks to be in backwards and "most" of the T&D MFG's only make it in a right-hand angle configuration.

Weatherproof piping (galv/painting) and escutcheon on the drain to exterior.
