Ensure you have the right tap for your keg
Depressurising a keg is an important step before or after use, especially if you don't have a tap to pour out the beverage. It is also necessary if you want to reuse the keg later. To depressurise a keg, you will need a flathead screwdriver and some pliers.
The first step is to ensure that you have the right tap for your keg. Different kegs have different taps, and using the wrong one can lead to leaks or difficulty in pouring. The tap should fit snugly into the keg and be designed for the specific type of beverage you plan to dispense.
Once you have the correct tap, you can attach it to the keg. This process can vary depending on the type of keg and tap you have. Follow the manufacturer's instructions carefully to ensure a proper fit.
If your keg is overpressurised, you may need to release some pressure before attaching the tap. This can be done by pressing down on the ball pin located at the top of the keg with a flathead screwdriver. Gently press the screwdriver against the ball pin and hold it down until you hear a sizzling sound, indicating that the pressure is being released. Continue to hold the pin down until the sizzling sound stops, ensuring that all the pressure has been released.
After depressurising the keg, you can now attach the tap. Make sure the tap is securely attached to the keg according to the manufacturer's instructions. This may involve using washers or other sealing mechanisms to ensure a tight fit and prevent leaks.
With the right tap securely attached, you can now enjoy your beverage. Remember to follow any additional instructions provided by the manufacturer for the specific type of tap and keg you are using.

Use a flathead screwdriver
Depressurizing a plastic keg can be a delicate process, and it is important to take the necessary precautions and steps to do it safely and effectively. Here is a detailed guide on how to use a flathead screwdriver to depressurize a plastic keg:
First, it is crucial to take safety measures. Always depressurize the keg outdoors, as a small amount of beer will usually spurt out during the process, which can create a mess. Place the keg on a surface that can be easily cleaned, such as pavement. Wear old clothes that you don't mind getting dirty, as the beer may splash onto your attire. It is also recommended to lean away from the keg while working to minimize the chances of getting beer on yourself.
Now, let's begin the process of depressurizing the keg with a flathead screwdriver:
- Locate the ball pin: Look at the top of the keg; you will find a rounded, circular metal pin stuck in the opening of the keg. This is the ball pin, which you will need to press down on to release the pressure.
- Use the flathead screwdriver: Position the flathead screwdriver so that it is directly above the ball pin. Gently press down on the ball pin with the screwdriver to start releasing the pressure. You may need to apply a firm but controlled amount of force.
- Maintain control: As you press down on the ball pin, be prepared for a small release of pressure and beer. Maintain a steady grip on the screwdriver and lean away from the keg to avoid any splashes.
- Release the pressure gradually: Do not attempt to release all the pressure at once. Slowly lift the ball pin with the screwdriver, taking breaks if needed to ensure a controlled release of pressure.
- Monitor the process: Keep an eye on the pressure release. Once the pressure has been released, and you hear a hissing sound, it indicates that the keg is depressurized.
- Clean up: After depressurizing the keg, you may need to clean up any spilled beer. Use a towel or a hose to wash away any mess and ensure the area is clean and safe.
By following these steps and using a flathead screwdriver, you can safely and effectively depressurize a plastic keg. Remember always to prioritize safety and take your time during the process to avoid any accidents or messes.

Press the screwdriver against the ball pin
To depressurise a plastic keg, you will need a flathead screwdriver. First, take your screwdriver and gently press it against the ball pin. You will need to apply a very gentle downward pressure on the pin until you hear a sizzling sound, similar to when you open a bottle of soda. This indicates that pressure is being released from the keg.
It is important to continue to press the screwdriver against the pin and hold it down until all the pressure is released. You will know that all the pressure has been released when the sizzling sound stops. Once the sound stops, you can remove the screwdriver, and your keg will be fully depressurised.
The process of depressurising a keg is quite simple and similar to tapping a fresh keg. It is important to ensure that you have the right tools, such as a flathead screwdriver, and to perform the steps gently to avoid any damage to the keg or injury to yourself.
Additionally, if you are unable to find a screwdriver, you can simply press down on the ball on the ball valve at the top of the keg to release the pressure. This method may be easier for some, as it does not require any additional tools. However, using a screwdriver provides more control and can help ensure a slow and gradual release of pressure.

Hold down the ball pin until all pressure is released
Depressurizing a keg is quite simple, but it is important to remember to do it before or after use, especially if you don't have a tap to get out the beer. It is also important to note that it is especially hard to depressurize a full keg, so it is recommended to have someone help you.
To start the process of depressurizing, bring your keg outside. Always depressurize your keg outside, as a little beer will usually spurt out of the keg during the process. Place the keg on a surface that can be easily cleaned, such as pavement.
Now, locate the ball pin. Look at the top of the keg. At the center of the keg, there should be a rounded, circular metal pin stuck in the opening of the keg. This is the ball pin, which you will need to press down on to depressurize the keg. Hold down the ball pin until all pressure is released.
After this, you can pump the keg until beer comes out of the nozzle at the desired pressure. Do not push down on the lever until the tap is locked into place.

Use a drill or a chisel or a keg coupler with a pressure relief valve
Depressurising a keg can be a tricky process, so it is important to take the necessary precautions and follow the correct steps. Here is a guide on how to depressurise a plastic keg using a drill, a chisel, or a keg coupler with a pressure relief valve:
Using a Drill or a Chisel
Using a drill or a chisel to depressurise a keg is possible, but it is important to note that these methods can be risky and may not be the safest options. One source mentions that these methods are "sketchy". If you choose to use a drill or a chisel, proceed with caution and be prepared for potential issues.
To use these tools, you would need to carefully apply pressure to the ball pin, which is located at the centre of the keg's opening, by gently pressing or tapping with the drill or chisel. This action should release pressure, but it requires careful maneuvering to avoid any accidents or damage to the keg.
Using a Keg Coupler with a Pressure Relief Valve
Using a keg coupler is generally a safer and more recommended method for depressurising a keg. Here are the steps to follow:
- Purchase a keg coupler that fits your keg.
- Attach the hoses to the coupler.
- Locate the ball pin on the keg. It is usually a rounded, circular metal pin in the centre of the keg's opening.
- Press down on the ball pin with a flathead screwdriver. Gently press it downward until you hear a sizzling sound, indicating that pressure is being released.
- Continue to hold down the ball pin with the screwdriver until all the pressure is released. You will know this when the sizzling sound stops.
- Remove and discard the ball pin.
- Use the screwdriver to pry up the retaining ring, which is a small metallic ring circling the area outside where the ball pin was.
- Pull out the retaining ring using needle-nose pliers.
- Move the inner tube counterclockwise with a hammer, and then pull it out.
- Always perform this process outdoors and wear old clothes to avoid any mess or damage to your clothing.
Remember to exercise caution when working with pressurised containers, and if possible, have someone assist you, especially when dealing with a full keg.
