i made a getto ic mister what can i do to stop it from leaking down? ive put a spare pump with a hose in the top of the washer tank. i thought that would solve the problem. nope. ive tried lawn mower fuel filter inline. nope. fish tank check valve. nope. i know i need a crack pressure valve from accuspray but i dont want to use that. i found great nozzles that can provide a good mist at speed, but they are just sprayers not valves. crack vlave is my absolute last resort any other suggestions. tomorrow im gonna try a couple other ideas. anyone that knows about physics, im trying to come up with a bleed off valve that vents the hose at the top when the pump is off so it breaks the cyphoning effect. any sugg.
