i am in the process of relocating my sump from under the tank to a shed/fishroom in the back yard. the tank is a standard 180 with duel overflows. i am looking for advice on what size spaflex to run back to the sump . the vertical head is right at 8 feet with about 35 feet of horizontal run.i will be using a pump that has a flow rate of 2800gph. the maximum head for this pump is 15 feet. would also like recomendations on return pipe size. i was thinking of running a 2" supply line split in two at the tank and drilling the back of tank for bulk heads . this would free up the bulk heads in the overflows to setup a quiet fail safe return. for the return i will use gate valves on the main drains with the overflow drains wide open. any thoughts, pictures, or comments welcome.
