I have a new Pentair Superflo pump. On my old pump, I used to be able to connect my air compressor to the drain plugs and put a rubber plug in the hole that leads to the pump motor. However, on the Superflo, the hole leading to the motor is much larger. Do I need to plug this? Or is it okay to just leave it open? The multiport would be closed, but I'm also not sure if compressed air should be making it there. In other words, I'm not sure if putting the pump motor and multiport under air pressure is okay or not. Ideally, I would just plug the Superflo, but I don't know if there is a large enough plug for that opening.
