Repair kits are cheaper than buying individual parts (thou depends where purchased). spindles that pass through tail valves/bush assembles need changing at same time.I have already replaced parts 362 and 363, so I don't need a repair kit.
The water is leaking either from the un numbered item or 364 it needs dismantling to confirm.If water is leaking from 364 then you need RK509ariston.Trouble is, I can't really see where the leak is actually from.
The link you mention is for a big nut but it appears that I am after a bush with screws like this.
The diverter valve controls your system water to the rads or the plate heat exchanger whereas the water in the diaphragm section (364) is mains water, the two never mix.The two parts already bought are just weeks/days old.
Just can't seem to see where the leak's source is.
I know the spindle on Part 363 is pushed through to the spndle on the diaghram in Part 364.
Should water be passing through as well please? Or is it just a switch type system with no water feed?
