I have an American Standard Hampton faucet that over time the flow has been more and more restricted. I have city water and great water pressure in all other faucets. Even the spray handle seems to have good pressure. I have replaced the spout assembly as I couldn't get the aerator out so I know that isn't the issue. The problem is the same no matter whether I use the left/right/both faucets.

I removed and reinstalled the diverter and that seems to help a bit. Is this the next part to replace or am I missing something entirely here?

Thanks.
