went to today to have a look and where the tube joins the water tank it had all fallen aprt, just left with springs etc but look like there is a clip missing?
Are you referring to the stop valve that goes into the back of the water tank?
If so you need to look up the bits your need on the schemetic parts diagram as each part is seperate. If you haven’t got a copy or access to Connect then email me and I’ll send you a drawing.
