I should state I use the Python to drain my 75g (sink) and use the FX5 to drain the 210g into the garden. If I could get that contraption I made to suck more it would replace my python faucet pump. I did try it outside at the garden hose bib but got the same results as using it attached to the kitchen faucet. I could use it w/o the faucet/hose bib on and just drain by gravity feed but then we are talking hours.
