My old pump was the cheapest of the cheap from Harbor Frieght, it worked semi-ok with a 25ft coil. I decided to upgrade my IC to 50ft and now it barely trickles through the copper coil. I have a feeling I would go faster peeing.
So without doing something that is insane overkill what are your experiences with something like this one? What would be the best way to throttle it? Stick a ball valve from a hose nozzle over it?
