Washer jet bottle pissing water away!

[Daz.]

Is there a known common reason why every last drop of water I pour into the water bottle just comes out behind the arch liner? lol

It's funny and quite annoying at the same time, it comes out that quick by the time I've shut the bonnet, started the car and tried washing the windscreen its all gone

Same! is almost comedy-like to pour it in the top and watch it come out the bottom before the jug is empty, anyone know likely reasons/fixes??
