I made some tweaks to the system I posted about yesterday. Today, I increased the diameter of the outlet pipes from 3/4" to 1" so they can keep up with the pump more comfortably. Instead of sealing with silicon, I'm using a real bulkhead now, but it was so big that it needed a flat surface. Hence, the new 7-gallon recycle bin, which, seems appropriate somehow. There's also a section of flex-PVC to help get the drain angle I needed without stressing the overflow box.
