I put this together to test out bong function. I have a much taller pvc pipe that i will use but for testing i am using this scrap piece. So far... that pump got hot, the water didn't cool down, and its noisy. The noise is ok, but i want it to cool...
i think the main problem is im using it passive, and that its way to shot. Also note that the top vent holes seem very sub-sufficient for the hot water vapor to escape.
Also i noticed a slow leak on the output nozzle on the pump.
Oh and its leaking from the shower head area which i think is a bit too large... but this is just a mock up, once its finalized i will be using caulk(sp) or some glue to seal it up.
(im posting this on other cooling forms too...)
oops can some one move this
