Leak Mystery

[Coolpackard2017]

So I was losing water about and I knew that I needed to have the plumbing redone which I hired some guy to do so. But yet I still have a leak and he's clueless. Here's some information

- Fiberglass Pool
- Poolrite Skimmer box
- Hayward LED Light
- I pulled the light out and plugged the hole where the wire comes out of the niche with a rubber plug, thermaseal, and pool epoxy
- I have determined that the skimmer drain leaks or the pipe connecting to the drain leaks
- Once the drain is plugged the skimmer holds water - no plug water leaks!

-But with the drain plugged I filled the pool mid way to the skimmer entry point. And over night the water is about 1-2 inches below the bottom of the skimmer faceplates
-Returns are plugged as well.
-Water will maintain it's level about 1-2 inches below the skimmer faceplate.

I'm perplexed and lost as to why this thing is leaking/water level 1-2 inches below skimmer faceplate - the drain I understand and is probably obvious I think.

Does the pool have a main drain? What is the port in the skimmer that is horizontal?

That was the old drain line before this guy re-did all the plumbing. He's capped it with plumbers PVC blue glue. There is a main drain but not in use capped off on the bottom, no pipe attached.
