A flat basketball can decrease your game and stunt training. To inflate a basketball, you will need an air pump and a ball needle. First, attach the ball needle to the pump, then moisten it with water and stick the needle into the hole in the ball, which will look like a little black circle. Once the needle is inserted, start pumping. If you don't have a pump, you can use a compressed air can, like a keyboard cleaner, instead. There are also ways to test if your basketball is inflated properly, such as the drop test, where you hold the ball with the bottom of it 6' (72) from the ground and drop it. The ball should bounce back up to a height of just over 4' (49-54).
How to blow up a flat basketball:
| Characteristics | Values |
|---|---|
| Frequency of pumping air | Depends on the ball; some need daily pumping, while others need air once or twice a month |
| Air pump | Purchase a decent air pump for balls; can also use a bike pump with the proper needle |
| Inflation needle | Small, pointed attachment that connects to the pump; moisten the needle with water before inserting it into the hole of the ball |
| Pressure gauge | Assists in determining the precise air pressure to guarantee proper inflation; most basketballs have a recommended pressure range between 7-9 psi, with 8 psi being the most common recommendation |
| Ball test | Hold the ball with the bottom 6' (72") from the ground and drop it; the ball should bounce back up to a height of just over 4' (49-54"); if the ball reaches a lower height, inflate the ball some more and try again |

What You'll Learn
Get an air pump
To inflate a basketball, you'll need an air pump and a ball needle. You can purchase an air pump for balls at a reasonable price, and they are easy to find. If you already have a bike pump, you can use that, but you'll need to purchase a ball needle separately if your pump doesn't have one.
When choosing an air pump, opt for one designed specifically for inflating sports balls. These pumps typically include inflation needles, which are small, pointed attachments that connect to the pump. The needle must fit tightly into the valve to avoid air escaping while inflating. Spalding pumps, for example, have a built-in needle compartment in the handle for easy storage.
If you don't have access to a pump, you can use a compressed air can, such as a keyboard cleaner. Moisten one end of the tube, insert it into the basketball, and pull down the handle to inflate it. However, using a traditional air pump is generally the most effective and cost-efficient method for inflating a basketball.
Once you have your air pump and needle, you can begin the process of inflating your basketball. Attach the needle to the pump and moisten it with water. Locate the hole in the basketball, which will look like a small black circle, and insert the needle into it. Start pumping the ball, and remove the needle when it is inflated to your desired pressure.

Attach the needle to the ball
To attach the needle to the basketball, start by connecting the needle to the pump. Most pumps will come with a ball needle, but if yours does not, you will need to purchase one separately. The needle should fit tightly into the valve to avoid air escaping while inflating.
Once the needle is connected to the pump, moisten it with water. This will help the needle to pass through the rubber more easily. The hole where you insert the needle is a small black rubber circle. If you cannot find the hole, check with the manufacturer.
Now, insert the needle into the hole. Push it in firmly, but be careful not to bend or break the needle. You should feel a slight resistance as the needle passes through the rubber.
Once the needle is inserted, you can begin pumping air into the ball. Pump slowly and steadily, and occasionally pause to monitor the pressure with a pressure gauge. The recommended pressure for most basketballs is between 7-9 psi (pounds per square inch). Over-inflation can damage the integrity of the ball and cause it to explode, so it is important to pump slowly and monitor the pressure regularly.

Check the pressure with a pressure gauge
Checking the pressure of a basketball with a pressure gauge is a simple process. Pressure gauges can be purchased at most sporting goods stores or online. They are also included with some compressors.
To check the air pressure, simply insert the pressure gauge into the air valve on the basketball and take a reading. Most basketballs have a recommended pressure range of 7-9 psi (pounds per square inch). The recommended pressure for Spalding basketballs, for example, is 8 psi. It's important to inflate your basketball to the recommended pressure, as over-inflation can damage the integrity of the ball and cause it to perform poorly or even explode, which may result in severe injury.
If you don't have access to a pressure gauge, you can perform a simple bounce test to check the pressure of your basketball. Hold the ball with the bottom 6 feet (72 inches) from the ground and drop it. The ball should bounce back up so that the top of it reaches a height of just over 4 feet (49-54 inches). If the ball reaches a lower height, it needs more air.
It's a good idea to check the air pressure in your basketball before every game or practice session. This ensures that the ball is at the correct PSI and bounces predictably and consistently. Changes in temperature and humidity can affect the ball's air pressure, so it's also a good idea to check the pressure periodically throughout the season. To maintain the correct air pressure, store your basketball in a cool, dry place away from direct sunlight and extreme temperatures.

Do a bounce test
To perform a bounce test on a basketball, you can follow these steps:
- Ensure you have the necessary equipment: an air pump, a pressure gauge, and a tape measure or yardstick.
- Inflate the basketball using the air pump until it feels full but not overly hard. Most basketballs have a recommended pressure range of 7-9 psi (pounds per square inch).
- Remove the needle from the valve, and gently bounce the basketball on a flat surface a few times to check its inflation. It should have a consistent bounce and feel responsive.
- Use the pressure gauge to fine-tune the inflation to the recommended pressure.
- Prepare a wall or vertical surface next to a flat surface, such as a basketball court, concrete, or grass. The wall should be perpendicular to the flat surface.
- Use the tape measure or yardstick to mark every eight inches on the wall, starting from the floor and going up to a height of 40 inches. You should have five tape marks on the wall.
- Hold the basketball at waist level so that the bottom of it is aligned with the highest tape mark on the wall.
- Drop the basketball (do not push it down) and let it bounce back up and hit the ground a second time before catching it.
- Observe the bounce height and compare it to the tape marks on the wall. The basketball should bounce back up to a height of around 49-54 inches (4-5 feet).
- Repeat the bounce test a few times to ensure consistent results.
By performing this bounce test, you can ensure that your basketball is properly inflated and has the optimal bounce for playing.

Look for air leaks
A leaky basketball can be a frustrating experience, but understanding why your ball may be losing air is the first step in preventing future deflation. Regularly checking your basketball for any signs of wear or potential leaks is crucial. Here are some detailed ways to look for air leaks in a basketball:
Inspect for Damage
Regularly examine your basketball for any signs of damage, such as punctures, gouges, or rough surfaces. Even a small puncture from a nail or thorn can create a pathway for air to escape. Keep an eye out for tiny cracks and crevices that may have formed over time, allowing air to escape.
Check the Valve
The valve is the most common source of air leaks in basketballs. Before inflating your basketball, gently clean the valve with a moist cloth to remove any dirt or debris that may be obstructing it. Ensure that the valve is properly seated and not damaged, as this can also lead to air leaks.
Immersion Test
The immersion test is a simple and effective way to locate air leaks. Simply plunge your basketball into water and observe closely for any bubbles escaping to the surface. These bubbles indicate the presence of a leak and its location.
Acoustic Test
In a quiet environment, pump up your basketball and hold it close to your ear. Listen carefully for any faint hissing sounds, which can indicate the presence of even the smallest leaks. Once you've identified the leak, mark it with a small piece of tape or a waterproof marker to easily locate it later.
Temperature Changes
Just like a car tire, a basketball's air pressure can be affected by temperature changes. Cold air contracts, so a ball inflated in a warm room may seem deflated when taken to a colder environment. Ensure you store your basketball in a temperate environment to avoid unexpected air pressure changes.
