What should I do if I have a leaky water valve in my home?

If you have a leaky water valve in your home, you should first turn off the water supply to prevent further leakage. Then, you can try tightening the valve with a wrench to see if that stops the leak. If the leak persists, you may need to replace the valve or seek help from a professional plumber. It is important to address the issue promptly to prevent water damage and wastage.
