My Delta bathtub faucet is leaking. Can I replace the washer? The faucet that delivers water to the tub is the part leaking. I see a previous question about the handle leaking. My handle is not leaking, the actual faucet part is dripping. It is almost undetectable; I just noticed when hanging something from the faucet overnight to dry that it was still soaked in the morning. Any help will be appreciated. Also, I could not see the diagram in the previous answer. Anyone know why?
