Where does the check valve go?

I don’t have a check valve in mine

What size is outlet ?

I don’t know it’s on the description

will this pump only turn on when water is high enough ?

You must buy the float switch if you want that function

Can I use this for a ballast bag on my boat?

Yes. I would think so. Not sure about the duty cycle but it is fast when you run it.
