Thanks again for replying, saw the brass cap I thought I needed, but ike you I think I’ll get a plumber in to sort it properly,it hasn’t been an issue all these years it’s just the usual when you get a problem I’d prefer isolation valves in place, kitchen company at time where a nightmare.
I’ve just measured internal depth roughly and it’s 50cm
to front of machine then 6cm to end of metal door, plus 18mm cabinet door. Manual says 540mm but looks like 560mm to me, won’t find out till I take it out.
Thanks for your all your help and advice.
Appreciated.
