Citroen Mist washer jets

Guys
after a bit of advice, bought some C3 misters for my 200, all fitted and even changed the short pipes to them with new ones but dont seem to be working very well, the water just about reaches the bottom of the screen even at speed, could this be a blockage somewhere or could the pump do with changing? did blow down the tube and seem to be clear.
 
I bought ones for an Alfa Romeo, had to trim them slightly to fit right but their great. When stationary the mist nearly clears the screen completely but when moving are perfect, we're about £7 a pair for genuine ones.
