Thanks for the input!

I doubt you'll have any leaks. Dont forget to give it a 1/4 turn when you put the pieces to be glued together to ensure a proper seal. Also make sure the pieces bottom out when shoved together.
Lastly, if you're going to T off one of your drains to the refugium, you need a ball valve after the T (before it gets to the skimmer area) and another one after the T (before it gets to the refugium). That way you can control the flow into the refugium and to the skimmer area of your sump. I thought just a valve to the refugium was enough, but its not, you get a weird syphon type action if you dont also ball valve to restrict flow into the skimmer area, forcing it into the refugium. Also, without the two valves you will have really bad echoing from water and air mixing in the pipe and its an awful noise. The two ball valves ensure that only water is going through the pipes by the time you fine tune them and this is what makes the drain quiet.
