Where to learn plumbing

The first thing you need to decide on is the type of overflow system (herbie, durso, bean animal) you want and then go from there. Researching these topics will also show you how most of the plumbing is set up. Melev's Reef website is good for getting sump info as well. It's pretty easy to plumb PVC it's just a matter of knowing what pieces to buy and put lots of unions in so you can easily take things apart and adjust the piping.
