You've got the wrong end of the stick entirely DP. By my comment "I did have a quick look on eBay, that new part is almost half the price on there than it was at City Plumbing" I wasn't suggesting at all that he should have supplied the part from eBay or considered supplying anything other than a genuine original part. My point was that even in trying to sell on the new diverter now I can see that they are only fetching just over half of what I am being charged for it, therefore not much £ can be recouped, that was my point. I know a fitter wouldn't use parts they cannot trust, that is why we agreed to have a new one from City Plumbing. I apprecite what you're saying but that's not the case here.
