Salty, do you have 1 1/4" drain hoses for this box? I know that our overflow boxes use drain hoses. If your box has bulk heads, and PVC pieces, then the bulkheads go into the box with the long threaded part extending outside the box, and the PVC pieces should fit inside that part that is outside the box. Once those are in place and glued you should be able to fit a drain hose on them. I just read your other post and it sounds like the other guys got it right, so if yours doesn't work like this, you need to mod it or get a different one.
