our Mondella WELS 5 Star 6L/min 35mm Stainless Steel Resonance Side Pin Lever Vege Spray Sink Mixer has started dripping just after we turn it off but also, when it is on, it leaks (ie flows) from the button on the nozzle that toggles from spray to stream - we usually have it on stream but it makes no difference, it leaks on either setting.
Is this something I can fix - maybe a spring or washer in there (from what I've seen I can't undo the nozzle end) or is this a replacement situation? Happy to call in a plumber but would rather know if I need to have a new tap handy for installation first.
leaks from the switch when on, drips after turning off but only for a few seconds
