Pop up drain emitter dislodges - need to be glued?
I just got a new pop up drain installed. When it rains, the pop up drain emitter (green part) comes out of the PVC elbow. Just the emitter need ot be glued, or screwed from inside?

What kind of pop-up emitter are you talking about??? Is this part of an irrigation system? Is it those problematic pop-ups people put on their downspouts?

It is part of an underground drain from gutter.
Part is similar to this:

Add 2 screws driven from the outside. Hex head screws would be easier to remove when necessary.

I was wondering about sizing.
The downspout is 3x4, connecting to a 4" round underground PVC. I am assuming this should work from a flow perspective?
I believe a 4" pipe can do 81 GPM
A 3x4 gutter 95 GPM?
I think the pop-up's are rated at 40 GPM. Just wondering if the system is sized right before I put in screws.

Keep an eye on that system. I've removed many of them. Because the water has to flow uphill at the end much of the debris and dirt is trapped in the pipe underground so they are prone to clogging.

Mine is brand new and has good slope. But I agree dirt can easily accumulate in there.
Just wondering where my cap is rated for the expected water-flow... If I screw it in, and it can not handle flow I am afraid it woudl damage system or leak somewhere.

They don't have flow ratings as much of that depends on everything else upstream. A lot of fall in the line using smooth wall pvc pipe and a sweep elbow will flow more water than a shallowly pitched corrugated pipe with a sharp 90 degree fitting at the end. If you are concerned about it restricting the flow don't attach it. That way if water pressure builds behind it it will blow the whole thing off the end of the pipe allowing unrestricted flow. Most I run into are not attached and stay in place fine but if it becomes a problem you can take a shovel of sod from the side and run a stainless steel screw in to hold it.
