I have a single-lever American Standard kitchen faucet, now about four years old. Suddenly it has started squeaking when I swing the faucet from side to side. Like an O-ring is squeaking or some such. I tried squirting some WD40 around the base to no avail,
Can anyone suggest anything. I really don't want to take the faucet apart, but maybe that is what I'll have to do?
Thanks
Duke
