1. Any reason you wouldn't want to incorporate the bubble trap in figure 2 into the drain line to the sump or is it not needed because you have a bubble trap between the skimmer and the return pump.
2. What is the purpose of installing a tee in the return line and routing it back to the skimmer compartment. I have seen that several times but didn't understand the purpose.
I just finished building my DIY HOB
Overflow and the sump is my next project.
