Have been wanting to do the same thing with mine eventually. I seen a guy who had a youtube video that made a lop where he had a bucket inside and a little pump which he ran using a corded hand drill. I'll see if I can find that video.
This to me is the gold standard and the one I would like to use: https://www.youtube.com/watch?v=-4JvXpyu-lU
He is using a sump pump.
