And then use some of this if needed:Stick the fitting on and secure with a couple sheet metal screws if necessary?

Beware, plugging the lower pipe reduces your spillway by half. If you get a rain storm that overwhelms the second pipe, be prepared to open the first pipe. Water over flowing your dam can cut the dam very quickly.
Tap it on snug and it will do fine. That will also permit you to remove it if you want to lower the water level again.You don't need to glue it just stick it on.
If you talking about the plug he installed being water tight. That plug is what we use to test plumbing, and to just keep things out until a fixture is installed.I am not sure how water tight your cap is, but a couple layers of electrical tape should help, or a little caulk on the inside.
All the best,
