Where to learn plumbing

[zooz]

Hello,

So I am deciding to finally build a new tank with a sump this time. LFS are charging $1000 to do the plumbing on my 100G build 40 x 24 x 24. I rather learn and do it myself to feel a sense of ownership and have fun doing it. I'm just not sure on how to go about plumbing the sump and return. Anyone know any good sites, videos, books etc?
