Dave,
You are correct that the pump has an intake hose and an outlet hose. The intake hose is currently attached to the lid of the water reservoir so that I can invert the reservoir (a 1 gallon jug) above the pump, as it doesn't currently have enough juice to self-prime.
However, the individual I got this idea from assured me that utilizing a transformer capable of 2 amps would allow the pump to draw water up to 15 inches, and would easily run 6 misting nozzles. So, I ordered a laptop AC converter that is 12 volts, 3 amps, and I am hoping this will allow me to place the reservoir below the pump (which I am sure will happen).
As for noise, it is a little noisy. It sounds about like a loud, imballanced computer fan when it runs. For this reason, I plan to somehow insulate the motor to reduce the noise. However, since it will only run for 1 minute a few times per day, I don't see this as being much of a problem.
Like I said in a previous post, if you are planning on using a misting system for more than 3 tanks, you should probably spend the $100 on a manufactured system. Otherwise, this does a pretty decent job for about half the money.
Let me know if you have any other questions.
