The thought has crossed my mind John, but something like a windshield washer pump is about 100x the flow needed. How well they might work after being restricted or the current turned down is an unknown. They are also often designed to go in the tank, or plug into a port on the bottom of the tank, both of which precludes using any tank but the matching one if you want a dependable seal. And those are too big for this. I don't need, nor want to carry a nearly gallon tank on the back of the gantry. That, because it higher than the mister nozzle, would also lead to syphon problems when turned off, so that idea got rapidly discarded. A teeny centrifugal pump might work, as their draw goes down with lowered flow because its restricted, but I've not come across such a critter. They don't self prime either. Until I did an ebay search just now, teeny 3L/minute versions that could sit beside the coke bottle at $4 to $8 prices, all a month+ away in china. Looks like they'd be right at home in a windshield washer circuit. One looks interesting, headline says centrifugal until you look at the specs at the bottom of the page, it too is a gear pump, not centrifugal. Near locked rotor amps to drive it at restricted flows IOW. Nope. But the one most advertised is centrifugal. Heavy current at full flow, could be over an amp. I ordered one $4.29 with ship) to play with, arrival late April... :( In the meantime we'll check the cap tube out. Thanks John.
