How would I fix my kitchen faucet it is very loose on the sink - still works fine - but I know this can't be good for it.
It is a one handle with spray diverter.
It didn't just gradually get loose - just one day it was like that.

I need something like 'anatomy of a faucet' - as I have no clue what to do.
I can follow directions though!

Thanks in advance

Nancy
