I recently drilled the back of my tank with 2 drains and 1 return with 1" bulkheads. They are located inside my overflow box. My question is: I see some people T off with a cap and a hole on top and others just run a 90* elbow leading down to the sump. What is the purpose of the T and is it better than just a 90??
I'm basically running an Herbie with one main drain and the secondary is an emergency drain. Any feedback is appreciated, thanks! :up:
