1" Emergency drain, could swap them, I suppose. Probably fine the way it is.

Our hydro bill went up 7% this past month and so having a powerhog of a return pump going 24/7 is a real concern for me.

Just a thought.

HMMMMMM, yeah . Not really sure if I want me power bill to go much higher. The DC pump uses 40W at full speed.
