I need help identifying what type of faucet I need or if there's a simple fix. I own a mobile home built in 1997. I noticed today that the cold water will not turn off. I have no idea how to fix it. Is there an easy fix? If I need a new faucet system, I don't know what to look for. It has two handles attached on a chrome wall mount with the chrome spout in the middle. The mount itself measures 10 inches long. Is that what I look for or do I measure something else?
