sounds to me likr you had a few chaps in who didnt know their arse from their elbow!

sounds to like you have some sludge issues (yeah I know you had it flushed when it was installed but have you had the water check of the inhibiter topped since then)

I would get on to keston themselves and get a recommendation from them as to who to contract to sort this out, three months and "you have too many valves" is bloooody ridiculous

I apologise I see that you have had re flushed, i missed that bit

still get someone in who knows whats what, you have an issue with your system that needs sorting out by someone knowledgable, I would say that there is no way you will get anywhere here as, speaking for mysel o course, would need to lock horns with it and look it over.

good luck
