I'm getting quite a few of these awful boilers where the diverter needs changing, or the plate heat exchanger alone needs replacing.
I'm after a tool that will allow me to undo the bottom left hand nut without stripping out the fill valve assembly.
Any thoughts?

I tried a tap spanner today when changing diverter, but nut was too solid so gave up and removed the fill assembly

I'd just remove the lot.

you can guarantee that as soon as you try to get the diverter out you will break something and the fill valve only takes a minute or 2 to remove.

I usually take a fill valve with me nowadays after the old valve spigot broke off in the diverter.
