Having a new tank built that will come with a Reef Savvy overflow box,, my plan for the new tank was to put a gate valve between my Eco Tech M1 return pump and my return lines ,, I still think this is the best way to do it ,, that being said,, I have never used this type of a overflow box
All of the You Tube Videos that I have seen of this overflow box ,, everyone using this box has a gate valve mounted into the main drain line from the overflow box to the sump tank ,, the way I understand it ,, this box has 3 return lines ,, the main drain line ,, a back up line and yet another back up line. Also ,, what size of PVC pipe is used on these lines?
