I flick for water, just a splash, and wait till the pump summons fluid from the reservoir. A second passes and water arrives in a bloosh! Between flicking and water arriving I've now learned to modulate the amount of intermediary mini-flicks to summon just a splash. Then the frigging headlamp skooshers activate! Rinse and repeat... What's wrong with fitting a simple (as the 8P had) non return valve in the line somewhere - that way there'd be water on demand when you flick, without all the finger ballet?!! Or is it just mine?
