Creating a PVC drain header for the branch lines should not be done.
Same reason as not running PVC with sprinkler head tees. Not an approved
material.

Yes, I do think that is the way to go, but it is a sprink contractor making
the suggestion. I'm trying to justify a response one way or the other.

So you have a "tree" system ESFR you want to turn into a "grid" system with
plastic pipe.. Sounds like a bunch of calcs to be done. From "my" point of
view I would tie 2 branch lines together like a gang drain come off that to a
valve in the ceiling with steel pipe Depending on the size of
Why not fabricate small pieces (1-0) with a outlet for the head and put a
grooved cap on the end to flush at later time.
Long term solution imho

The answer would be no. Right?
Plastic is fine for drain, not listed. But all piping before the valve is.

Once downstream of a labeled valve, fine. Upstream, and including valve, no. A
gang drain, for example uses materials complying with normal NFPA 13 materials.
I’m assuming valve at each branch line in order to get adequate flow.
Best.

I say it's fine if you have drain valves at the end of each line and transition
to pvc after the valve. But that may be expensive.
So I say pvc is ok after the drain valve.
But is that practical?
