I just bought a new bathroom sink faucet and was all set to install it. When I went to shut off the hot and cold water valves under the sink the hot water valve stem broke off. I am unable to shut the hot water off now. My question is how do I replace the stem? Am I able to replace just the stem, or do I need to replace the entire valve? Please help me as I cannot afford to hire a plumber for the job. Thanks!

Before we can help we need more information. Name of faucet. Where did you purchase it? Can't you return it under warranty and get a new one? Let me know, Tom

The problem is not with the faucet, it is the water shut off valve under the sink. When I tried to shut off the hot water, the valve stem broke. So I need to know how to replce the broken stem before I can install my new faucet.

Purchase a new angle stop.(see image) and simply swap the new stem and washer assembly for the old one. Good luck, Tom
