Hi Tom... Couple of days ago I rec'd your reply about my low hot water pressure in kitchen sink, I did as you advised, to remove parts to seats and springs and clean out any sediment, then turn water on to flush out. I did this and didn't find any sediment or built up of anything, I inserted a thin wire rod and also didn't disturb any sediment. When I replaced everything the pressure was even worse. What more do I need to do or what didn't I do right. I have a single lever Delta faucet. Thank you.

When you flushed out the supplies did you have a strong stream? Tom
