did a job today and my wand wouldnt stop spraying, even when trigger wasnt being  pulled.... any ideas??? couldnt see anything untoward with the mechanism visually......

Either the spring is not pushing the plunger back up  ( on this photo the spring cannot be seen its inside the thread bit at the bottom which is not cuts away ) or thier is some obstruction stopping the Teflon seal  ( the White washer in the middle) seating correctly....... so allowing water to escape past.

Strip it down and clean it out
