I have a kitchen faucet whose surface consists of a base metal ring, a body sleeve, and a metal handle. At first glance it appears all metal parts are in contact with each other. Measurements reveal the base metal ring is grounded (measured 0 volts AC and several ohms to a grounded receptacle's ground pin), but the sleeve and handle are not grounded.
Is there any code violation here? This faucet is 20 years old. I don't mind replacing the faucet if it helps.
