To fix a presta valve, unscrew the cap, unscrew the nut, pull out the inner tube, find the hole, and patch it.

How Do You Properly Inflate A Presta Valve?
To inflate a presta valve, unscrew the top of the valve, insert the pump nozzle, and pump until the tire is inflated to the desired level.
Inflating a presta valve is a two-step process. First, you’ll need to unscrew the small cap at the top of the valve. Next, use a bike pump to inflate the tire. Be sure to not over-inflate the tire – you should only fill it to the max psi listed on the side of the tire. Finally, screw the cap back onto the valve to keep the air in.
Here’s a step-by-step guide to inflating a presta valve:
1. Unscrew the small cap at the top of the valve.
2. Use a bike pump to inflate the tire.
3. Fill the tire to the max psi listed on the side of the tire.
4. Screw the cap back onto the valve to keep the air in.
What Is The Recommended PSI For A Presta Valve?
If you have a presta valve on your bicycle tire, you may be wondering what the recommended PSI is. PSI stands for pounds per square inch. The recommended PSI for a presta valve is 80-100 PSI.
If you are unsure what PSI to inflate your presta valve to, err on the side of the lower number. You can always add more air if needed, but if you inflate to the higher number and the tire is too hard, you risk popping the tire.
Here is a quick and easy way to check your tire pressure:
1. Remove the cap from the presta valve.
2. Press down on the valve to release any air that may be in the tire.
3. Use a tire pressure gauge to check the PSI.
4. If the PSI is below 80, add air until it reaches the desired number.
5. Replace the cap on the presta valve.
It is important to check your tire pressure regularly to ensure that your tires are inflated to the proper PSI. This will help to prevent flats and other problems.
There is no one-size-fits-all answer to this question, as the best way to fix a presta valve will vary depending on the specific issue that is causing it to leak. However, some common methods for fixing a presta valve include tightening the valve nut, using a valve core tool to remove and then replace the valve core, and/or using a presta valve adapter to convert the valve to a Schrader valve.
