bro, try to visit local lfs and see how they install their beckett. If u are placing out sump, then the outlet from the beckett muz be higher than ur sump in order to prevent back flow. i suppose u sldnt place the beckett too far away, so as to maximise the efficiency. and one other thing, when u first get the beckett try to observe it for a day and adjust the tuning, if not tsunami might happen.
