just been looking at a waterpump out of a Mercedes Sprinter van... i whacked 12v through it and it drained my bathroom sink in about 5 seconds.
i'll see if i can do some tests with some kind of mesurement (probably a litre jug and a stopwatch lol ) and post back. looks promising tho, it has a lot of power and is fairly quiet to boot.
i was also messing around with a water pump that was going to be used to supply an electric toilet (the ones they use in loft conversions etc.) that was very noisy, but almost as powerfull, and *very* small (i'm talking 50% of a hydor l20 here..) more tomorow
