Y strainers

Jean-David Beyer

I made a "menorah" with 4 Gorton #1s. I Have a 3/4 " Y - strainer I want to put between the vent riser from the main and the "menorah." Does it make much of a difference if the clean out plug faces up or down? If it faces down would the screened part of the clean out fill up with condensate? If it would fill with condensate would draining the clean out once a week be sufficient?

Thanks
