Charlie. The three flag hinges should have an allen key underneath which raises the sash. If the part attached to the door is in contact with the part on the frame, it is in its lowest position and can only go up. As a uPVC door fitter I find most water issues are down to blocked drainage channels (routed in the threshold) Clear these and see if it helps. Kev (klplastics@graffiti.net)
