I have bought a pair of new diaphragms for my boiler. I'm hoping it will cure the problem of both CH and DHW pins being open at the same time, the CH pin seems to be "sticky" and not always notice when DHW flow is requested.
I have the two new diaphragms, is this all I need to replace? Some of the guides I have read appear to have new pins too, as long as I lubricate with silicone grease I assume I am OK to reuse what is there?
I'd also like to clean out as much of the internals as possible, but I don't think I can remove the heat exchangers without new O rings to replace the old ones with? I might just have a go at the diverter first and see if that helps!
