Hard pvc makes it looks clean but when you start moving equipment around and change things up its hard
Yeah ,gonna go this way.You can do hard pvc... then use tubing... easier for things like pumps where you need some flexibility... or drains when you need to make easy turns.
Thanks JB,how exactly would you do it?.You are doing the right thing going with what Skene recommends. I used hard pvc only and if I could do it over again I would. Good luck.
