Sorry WeeZard I was referring to the Bulkhead fitting (drain) at the bottom of the bucket?.often sold simply as an ebb & flow fitting. Even with the e&f filters some folk complain about roots growing all the way back to the controller, plugging up the drain and overflowing the bucket. Thought that I might get in a second line of defense with an additional screen. I??ve certainly got plenty of time to let the ??glue? dry. Just wondering if brass could get along with the nute chemistry.

Thanks,
