Ok, so I made a couple crappy diagrams of what I could use to do the plumbing. Please tell me if it would work, or why it wouldn't and what would work. I am not going to be drilling any more holes in the tank or adding an overflow box.
Edit: bahhhhh I guess I am making an overflow box
It is just the tank with 2 holes (one is higher than the other, not sure why). What size pipes should I be using? I have a couple 1" ball valves at home...I
think they are one inch anyway... I believe the bulkheads are also one inch, but cannot find the measuring tape, lol. For the sump pump we have an oceanrunner 3500
