On my pipe there is a separate nozzle inside a holder screwed on the end. You can undo the little holder (using 2 ten mm spanners) and take the little spray jet out, which has a cross drilling, inside the cross drilling is a ball and spring, so it kind of sprays each side. What I did in the end was to spin the pump shaft with a drill to check it was spraying where the the basket would be, and put put the clutch back.
