Plumbing a sump varies in so many ways because of various equipment answering you would be impossible. What I will tell you from what I learned is: Plumb as much as you can with
pvc, avoid hoses. Use
pvc unions in a few places to help you be able to remove sections of piping when you need to.
Majority of the parts can be found at Lowes.
If I were you I'd be watching tons of youtube videos.
