Leaking water pump seals

Having carefully overhauled the pump it is working well and running smoothly.
When I fitted the carbon seals I pressed them snugly into the housings as far as they would go. I'm now wondering if I should have simply have got them started in the housing and then allowed them to find their own depth as the whole assembly was bolted together.

I'm worried that the working face, which I assume is meant to bear each side on the smooth side of the boss on the impeller, is just slightly too far away and is not being forced tightly enough to make a good seal.

I'm not going anywhere for avery long time yet so I can live with it in the hope that it magically heals itself' it doesn't seem to leak when stationary.
