Great Idea I was meandering this thought around in my head and thought wait a minute a pool pump. They even have parts at wal mart!Wheat;2884909; said:Hayward Super pump or Max-flo pump. High flow. I think it was 50 gal/min @ 20'. I use one, it's noisy and expensive to run, but cost only around $200.
edit: Plus, if you need a part, or if the the motor ever dies, you can probably get it locally. These are pool pumps.
