Did you had any problem with that?
I have never encountered such behaviour and have emptied few cans of spray on it in the past. This device is old few years, maybe new versions of devices have such thing but not old ones?

I guess when fluid will flow slowly backwards (becouse of pump's leak) to the pump between squirts it will be unable get strict doses...
I have tested only with a pump on same level as water, ill do the test with long hose tommorow
