Thanks guys. I will certainly use the paper clip method. For flow testing, can I just have an elevated water supply flow water into a jet connected by hose/tube of some sort, let the water flow by gravity, collect the water exiting the jet into a measuring container, and see how much water is collected over time? This seems like the easiest/cheapest way to do it. I saw some setups had pumps in them, but I don't get what that's for.
