Upcycling an old kegerator into a sparkling water dispenser is a great way to repurpose an appliance you no longer use and create a functional, eco-friendly device. This detailed guide will walk you through the process of converting your kegerator into a sparkling water dispenser, covering installation, adjustments, troubleshooting, optimization, and compatibility with related beer equipment.
Tools Required
- Kegerator
- Carbonation kit (CO2 tank, regulator, and gas lines)
- Sparkling water faucet
- Tubing (food-grade)
- T-fitting (for CO2 line)
- Pressure gauge
- Drill and drill bits (for faucet installation)
- Wrenches and pliers
- Gasket/sealant for securing parts
- Ice water bath (for cooling the water)
- Adjustable wrench
- Screwdriver
Installation of the Sparkling Water Dispenser System
1. Prepare the Kegerator
- Ensure your old kegerator is clean and free of any beer residue or impurities that could affect the taste of the sparkling water. Clean the inside with warm soapy water and rinse thoroughly.
- Remove any beer taps, keg couplers, and beer-specific fittings that may be present.
2. Install the Sparkling Water Faucet
- Identify the spot where the faucet will be installed. Typically, this would be where the beer tap used to be.
- Use a drill and appropriate drill bits to make a hole that fits the new sparkling water faucet securely.
- Install the faucet, ensuring it is tightly sealed with a gasket to prevent leaks. Secure it with the provided nuts or fittings.
3. Set Up the Carbonation System
- Install a CO2 tank into your kegerator. Position it securely inside the unit, typically in the base or the side compartment.
- Connect the CO2 tank to the regulator and adjust the pressure settings based on the desired carbonation level. Standard carbonation for sparkling water is typically between 30 to 40 psi, but this can vary based on personal preference and the temperature of the water.
- Use food-grade tubing to connect the CO2 regulator to the kegerator’s dispensing system. A T-fitting may be required to split the gas line for both beer (if you plan to still use the kegerator for beer) and sparkling water.
4. Prepare and Connect the Water Line
- Install a water line from the kegerator to the faucet. This will require additional food-grade tubing. Ensure the line is securely connected to avoid any water leaks.
- If you are planning on dispensing cold sparkling water, make sure the water line is insulated or kept in a cool environment.
Adjustment for Optimal Performance
1. Set the Right CO2 Pressure
- The correct CO2 pressure is essential for achieving the ideal carbonation. Too high or too low pressure can lead to over-carbonated or under-carbonated water.
- Experiment with the pressure until you find the right balance. Start with 30 psi and adjust based on taste and effervescence. Lower pressures may produce a softer carbonation, while higher pressures result in more bubbles.
2. Adjust the Water Temperature
- Cold water carbonates better and holds carbonation longer than warmer water. Ensure that your kegerator is set to the right temperature, typically between 36-40°F (2-4°C).
- If your kegerator’s cooling system is not sufficient, consider adding an external cooling solution or a refrigerator unit that can fit inside the kegerator.
3. Fine-Tune Faucet Flow
- The flow rate from the faucet can affect the drinking experience. Adjust the faucet’s flow control to prevent splashing or over-filling of glasses.
- Experiment with the faucet opening to ensure smooth dispensing without excess foam.
Troubleshooting Common Set-Up Issues
1. Leaking CO2
- If you notice that CO2 is leaking, check the connections between the CO2 tank, regulator, and tubing. Tighten all fittings using a wrench or pliers.
- Inspect the T-fitting and ensure there are no cracks or damage. Replace any faulty seals with new ones to prevent leaks.
2. Water Not Carbonating Properly
- If the water is not carbonating as expected, check the CO2 pressure setting. Ensure that the CO2 tank has enough pressure and that the regulator is working correctly.
- Inspect the water line for any kinks or blockages that might be restricting CO2 from flowing properly.
3. Faucet Not Dispensing Water
- If water is not dispensing, ensure that the faucet is fully open and there is no obstruction in the water line.
- Check the water supply line for any issues and verify that the pressure from the CO2 system is sufficient to push the water out of the faucet.
Customization and Optimization for Better Performance
1. Enhanced Carbonation Control
- To further customize your sparkling water dispenser, you can install a carbonation stone inside the keg or water container. This stone increases the surface area where CO2 bubbles interact with the water, leading to more consistent and efficient carbonation.
- Use a pressure gauge to monitor the CO2 pressure in real-time and fine-tune it based on the carbonation level you desire.
2. Upgrade the Faucet
- Consider upgrading the faucet to a specialized sparkling water faucet that controls the flow better and prevents excess foam. These faucets are designed for high-carbonation beverages and can improve your overall dispensing experience.
3. Utilize a Chilling Coil
- For more efficient cooling, consider adding a chilling coil in the water line. This will keep the water colder as it moves through the line, improving carbonation retention and offering a refreshing drink.
Comparison with Similar Products
While upcycling an old kegerator is a cost-effective way to create a sparkling water dispenser, it is not the only option. Here’s a comparison of alternative products:
1. Dedicated Sparkling Water Dispensers
- These are standalone devices specifically designed for sparkling water. They typically have built-in CO2 systems and are more compact than repurposed kegerators.
- Pros: Easy to use, compact design, no need for additional beer equipment.
- Cons: May not have the capacity or customization options of a kegerator system.
2. Countertop Sparkling Water Makers
- These are smaller, countertop machines that carbonate water with a CO2 canister. They are ideal for small batches of sparkling water.
- Pros: Convenient, no need for extensive modifications, easy to store.
- Cons: Lower capacity, less control over carbonation levels.
3. Kegerator-Based Dispensers
- A kegerator-based dispenser like this project offers a large capacity, better control over carbonation, and the ability to dispense both beer and sparkling water.
- Pros: Customizable, large capacity, multi-functional.
- Cons: Requires more space and installation time.
Compatibility with Other Beer Products
A kegerator-based sparkling water dispenser is highly compatible with various beer products, including keg systems, beer dispensers, and taps. If you plan to continue using your kegerator for both beer and sparkling water, the system’s dual functionality will be essential:
1. Keg Systems
- If you have a keg system for beer, the CO2 tank used for beer can also be utilized for the sparkling water system, allowing you to streamline your setup and reduce costs.
- Ensure that the CO2 pressure is properly adjusted for both beer and sparkling water, as they may require different levels of carbonation.
2. Beer Dispensers and Taps
- If you are using the same tap for both beer and sparkling water, ensure that you have a separate line or T-fitting to prevent cross-contamination of flavors.
- You may need a specialized faucet for sparkling water, as it will handle high-pressure carbonation better than a regular beer faucet.
By understanding how to properly set up and maintain your sparkling water dispenser, you can enjoy fresh, carbonated water on tap with the convenience and versatility of your old kegerator.
