<human>:  How to fix a leaking tap?
<bot>: To fix a leaking tap, you should first shut off the water supply to the tap. Then you can open the tap and unscrew the handle or faucet to check the source of the leak. You may need to replace the rubber washer or O-ring inside the faucet to stop the leak. If the leak is coming from the spout, then you may need to replace the valve stem and seats. Once the parts are replaced, you can turn the water supply back on and test the tap to make sure the leak has stopped.
