In many households, people rely on bottled sparkling water to meet their daily drinking needs. However, this method comes with several problems. Bottled water not only needs to be carried frequently, but also requires dedicated storage space. You also need to keep track of the remaining supply so that you can restock it in time. Although countertop sparkling water makers have a relatively low initial cost, they can be inconvenient to use. You need to fill them with water manually each time and repeat the carbonation process to produce enough sparkling water.
This is where an under-sink sparkling water system stands out. It can provide chilled sparkling water directly from the kitchen faucet, bringing great convenience to the household. However, products on the market vary greatly in price, functions, installation methods, and water output capacity.
This article will compare different types of sparkling water taps and representative products in detail. It will also provide a complete buying checklist to help you choose the most suitable sparkling water tap for your home.
What Is a Sparkling Water Tap for Home Use?
A sparkling water tap does not produce sparkling water through the faucet alone. A complete home sparkling water system usually consists of a faucet, chilling unit, carbonation unit, filter, CO₂ cylinder, pressure regulator, connecting tubes, and other components.
Tap water first flows into the under-sink unit, where it is filtered to reduce some impurities and improve the taste of the water. It is then chilled, as a lower water temperature helps CO₂ dissolve more effectively. Food-grade CO₂ then passes through the pressure regulator and enters the carbonation unit, where it mixes with the chilled water to create bubbles. Finally, the sparkling water flows out through the faucet.
It is important to distinguish between a “sparkling water tap only” and a “complete sparkling water system.” Purchasing only a sparkling water tap usually will not allow you to produce sparkling water because the essential carbonation equipment is not included. In addition, some products require users to purchase a food-grade CO₂ cylinder locally. Therefore, before buying, make sure you understand whether the product is a complete sparkling water system.
How Does a Sparkling Water Tap for Home Use Work?
Step 1 — Water Enters the Filtration System
The filter plays an important role in the system. It is mainly used to improve the taste of the water and reduce specific impurities, such as chlorine, unpleasant odors, and sediment. However, not every filter can remove every contaminant. Users should choose a suitable product based on local water quality and the certifications obtained by the filter.
The filter may also affect the incoming water flow. Therefore, check the minimum flow-rate requirement of the equipment to make sure the filter does not restrict the water excessively and prevent the system from operating normally.
Step 2 — The Water Is Chilled
A lower water temperature helps CO₂ dissolve more effectively, so the chilling system is a key component that affects the taste and stability of the sparkling water. Common chilling methods include chilled water tanks and continuous chilling systems. A chilled water tank cools and stores water in advance, while a continuous chilling system cools the water in real time.
When choosing a system, check the amount of water that can be dispensed at one time and the recovery time of the chilling system to make sure it can meet your household’s needs in different situations.
Step 3 — CO₂ Is Injected into the Chilled Water
Food-grade CO₂ enters the carbonation unit through a pressure regulator and mixes with the chilled water to create bubbles. However, the CO₂ pressure must be set strictly according to the manufacturer’s requirements. Higher pressure is not always better. Incorrect pressure may cause splashing, unstable carbonation, or even trigger the equipment’s protection system.
Step 4 — Sparkling Water Flows Through a Dedicated Waterway
Sparkling water should preferably flow through a separate internal waterway. This helps prevent it from mixing with regular hot and cold water and maintains the quality of the sparkling water.
A dedicated sparkling water tap is only responsible for dispensing sparkling water, while a multifunctional faucet can combine several types of water. Although a multifunctional faucet is more convenient, users should understand how to switch between and operate its different functions.

What Are the Main Types of Sparkling Water Taps for Home Use?
Dedicated Sparkling Water Tap
A dedicated sparkling water tap only provides sparkling water, chilled water, or filtered water. It usually requires an additional hole in the sink or countertop.
This type is suitable for households that want to keep their existing kitchen faucet, as the initial modifications are relatively limited. However, it may affect the overall clean and simple appearance of the countertop.
3-Way Sparkling Water Tap
A common 3-way sparkling water tap combination includes filtered water, chilled water, and sparkling water. One faucet is used to manage all drinking water functions.
However, regular kitchen hot and cold water may still require a separate main kitchen faucet. When purchasing, do not judge the product’s functions based only on the term “3-way.” You must confirm the three specific types of water it provides to avoid purchasing a product that does not meet your needs.
5-Way Multifunctional Kitchen Faucet
A 5-way multifunctional kitchen faucet can combine regular hot water, regular cold water, filtered water, chilled water, and sparkling water in one faucet.
This type is suitable for households renovating their kitchens or those that want to reduce the number of holes in the countertop. However, the under-sink connections are relatively complicated. Before purchasing, make sure each type of water has separate controls and an independent internal waterway to ensure convenient use and safe water quality.
For example, the Liliumfaucet 5-way solution combines several functions in one faucet, making it suitable for households that want to avoid installing an additional drinking water tap.
All-in-One Boiling, Chilled, and Sparkling Water System
This type of system provides boiling water, chilled water, and sparkling water. It is suitable for high-budget luxury kitchens.
However, these systems are usually larger, require more power, and have stricter installation and maintenance requirements. During use, special attention should be paid to child safety, proper boiling water control, and compliance with installation requirements.
Countertop Sparkling Water Maker
A countertop sparkling water maker is not a true sparkling water tap. It has a lower initial cost and does not require any changes to the kitchen plumbing.
However, users need to fill it with water manually, chill the bottles, and repeat the process during use. It is more suitable for people who drink sparkling water infrequently or for renters.

The multifunctional faucet can be presented as a key point of difference.
It should be clearly explained whether the CO₂ cylinder needs to be purchased locally. The equipment, voltage, connections, and installation requirements should also be introduced.
Real customer videos or installation examples can be used to improve credibility, while the suitable applications and limitations should also be listed.
The current Liliumfaucet under-sink system page states that the sparkling water output is approximately 6–8 liters per hour, while the amount of chilled water available in one continuous dispensing cycle is approximately 600–700 milliliters. Both 3-way and 5-way faucet configurations are available.
How to Choose a Sparkling Water Tap for Your Home
First Decide Which Water Functions You Need
Users can choose from the following functions:
- Regular cold water
- Regular hot water
- Filtered room-temperature water
- Filtered chilled water
- Sparkling water
- Instant boiling water
The following selection guidelines may help:
- If you only need sparkling water: choose a dedicated sparkling water tap.
- If you need filtered water, chilled water, and sparkling water: choose a 3-way system.
- If you want to keep full kitchen hot and cold water functions: choose a 5-way faucet.
- If you also need boiling water for tea and cooking: choose an all-in-one boiling, chilled, and sparkling water system.
Compare Sparkling Water Output, Not Only Tank Capacity
When choosing a sparkling water tap, do not focus only on the tank capacity. You should also check the sparkling water output per hour, the amount that can be dispensed continuously at one time, the chilling recovery time, and how long you need to wait after periods of high use.
You should distinguish between normal daily household use and concentrated demand during parties. A large tank does not necessarily mean a higher continuous sparkling water output.
Suggested household consumption categories are as follows:
- Low consumption: 1–2 liters per day
- Medium consumption: 2–2.5 liters per day
- High consumption: more than 5 liters per day
- Parties or home bars: require higher immediate and continuous dispensing capacity
Check Whether the Carbonation Level Can Be Adjusted
Some systems allow users to adjust the carbonation level through equipment settings or CO₂ pressure. However, users should not exceed the pressure specified by the manufacturer.
Water temperature, CO₂ pressure, dispensing speed, and water quality can all affect the carbonation experience. Users who prefer strong carbonation should prioritize real product demonstrations and customer feedback. Product comparisons should also explain whether the system produces fine, gentle bubbles or stronger carbonation.
Confirm the CO₂ Cylinder Specifications and Local Supply
Confirm whether the equipment includes a CO₂ cylinder and whether food-grade CO₂ is required. Check the cylinder size and connection type, and find out whether it can be refilled or exchanged locally.
Compare the long-term costs of small proprietary cylinders and larger refillable cylinders. Confirm whether the pressure regulator is included and whether the cylinder can be stored safely inside the cabinet.
Check Whether the Filtration System Is Suitable for Local Water Quality
Understand the main functions and certifications of the filter. Different filter cartridges may target chlorine, unpleasant odors, sediment, hardness, or specific contaminants.
Hard-water areas may require additional treatment. Excessive filtration may reduce the incoming water flow.
Before using an RO system, confirm compatibility with the equipment manufacturer. Avoid unsupported statements such as “filtered water is always healthier.”
Measure the Available Space Under the Sink
Measure the following before installation:
- Cabinet width
- Cabinet depth
- Cabinet height
- Space occupied by the drainpipe
- Space occupied by the garbage disposal
- Space required for the filter
- Space required for the CO₂ cylinder
- Ventilation space around the equipment
- Working space required for future filter and cylinder replacement
It is recommended to include an under-sink installation dimensions diagram in the article.
Confirm the Power Supply, Voltage, Water Pressure, and Inlet Flow Rate
Most chilled sparkling water systems require electricity. Confirm whether the system is available in a 110V, 220V, or 240V version. Plugs and voltages vary between countries.
Check the minimum and maximum incoming water pressure required by the equipment. Measure the actual water flow after the filter. Insufficient incoming water may affect refilling and continuous dispensing.
Do not only measure the unfiltered tap water pressure. Carefully review the manufacturer’s instructions before installation.
Choose a Multifunctional Faucet with Separate Waterways
Regular hot and cold water and filtered drinking water should preferably use separate internal waterways. Separate waterways help prevent drinking water from coming into contact with regular mixed water.
Confirm that the cartridge and internal waterway materials are suitable for drinking water. Check whether the faucet has clear function markings and avoid control designs that are easy to operate incorrectly.
For a 5-way faucet, the control method should be explained clearly.
Consider Noise and Ventilation
The compressor, chilling system, and pump may produce sound during operation. The sound is usually reduced when the cabinet door is closed.
The equipment needs sufficient airflow and should not be completely sealed inside a small cabinet. Noise is an important purchasing factor for users with open-plan kitchens.
It is recommended to watch a real operating video instead of relying only on product images.
Compare Warranty and After-Sales Service
Compare the following warranty and after-sales service information:
- Warranty period
- Whether the compressor, pump, and electronic components are covered
- Whether the faucet and equipment are covered by the same warranty
- Whether installation guidance is provided
- Whether remote diagnosis is available
- Whether local service personnel are available
- Whether faulty components are repaired or replaced
- Who pays the return shipping cost

How Should Different Households Choose?
Households with Fewer Than Two People
Give priority to a small under-sink system or countertop machine. Because there are fewer household members, there is no need to pursue very high output.
Pay attention to standby electricity consumption and under-sink space. Choose a more energy-efficient product that does not take up too much space while still meeting small but consistent daily sparkling water needs.
Households That Drink Large Amounts of Sparkling Water Every Day
Focus on comparing hourly output to make sure the system can meet frequent drinking needs.
Choose a larger CO₂ cylinder to reduce how often it needs to be replaced. Check the continuous dispensing capacity to avoid interruptions during periods of concentrated use.
At the same time, choose a system with filters and CO₂ cylinders that are easy to replace to reduce daily maintenance costs and time.
Households with Children
The control design should be clear and easy to understand for both children and adults.
If the system includes boiling water, a safety lock must be carefully considered to prevent children from touching it accidentally and being burned.
The CO₂ cylinder should be secured firmly to prevent it from falling and causing danger. Children should also not be allowed to adjust the pressure equipment by themselves.
Households Renovating Their Kitchens
Reserve power, installation space, and ventilation areas during the cabinet design stage.
A 3-way or 5-way integrated faucet can be given priority because it combines several functions, reduces the number of countertop holes, and improves the overall appearance of the kitchen.
Confirm the countertop hole and plumbing positions in advance to ensure smooth installation and better integration with the kitchen renovation.
Households with Completed Kitchens
Give priority to a dedicated faucet system that does not require major modifications.
Check whether a suitable electrical outlet is available to provide power to the equipment. Confirm whether the existing cabinet can accommodate the main unit and CO₂ cylinder to avoid installation problems caused by insufficient space.
Choose a solution that requires fewer changes to the existing kitchen facilities to reduce renovation costs and installation time.
Households That Frequently Make Cocktails
Pay attention to carbonation strength and consistency to meet the need for strong carbonation when making cocktails.
Choose a system with a lower dispensing temperature because colder water helps maintain the taste of cocktails.
Check the continuous dispensing capacity during periods of high demand to ensure that enough sparkling water can be provided when making several cocktails.
You may also consider installing a dedicated sparkling water tap in the home bar area for easier access and improved convenience.
How to Maintain a Sparkling Water Tap
Replacing the CO₂ Cylinder
Determine the replacement schedule based on usage. Consider replacing the cylinder when sparkling water output decreases noticeably or when the CO₂ cylinder pressure indicator is low.
Close the cylinder valve before removing it. Check the seal according to the instructions and make sure there are no leaks after the new cylinder is installed.
Using incompatible cylinders or connectors is not recommended because this may create safety risks.
Replacing the Filter
Replace the filter based on time, water consumption, or equipment reminders.
A new filter cartridge usually needs to be flushed after installation to remove residues left from the manufacturing process.
Failing to replace the filter for a long time may affect the taste and water flow and reduce the quality of the sparkling water.
Cleaning the Water Lines and Outlet
Clean or sanitize the system according to the manufacturer’s requirements. A dedicated cleaning solution or sanitizer may be used.
Clean the faucet outlet regularly to prevent scale and impurities from building up and affecting water flow.
After the system has not been used for a long time, flush the water lines before using it again to ensure the water is clean.
Checking Cabinet Ventilation and Water Leaks
Keep the ventilation areas around the equipment unobstructed to ensure proper heat dissipation.
Regularly inspect the connectors and tubing for signs of water leakage. Check whether the CO₂ tube is bent, as this may affect CO₂ delivery.
Do not place objects directly against the compressor ventilation area because this may affect heat dissipation and cause equipment problems.
Common Buying Mistakes
- Purchasing only the faucet without purchasing the carbonation unit, making it impossible to produce sparkling water.
- Assuming that all 3-way faucets have the same functions without confirming the specific types of water provided.
- Failing to confirm whether the CO₂ cylinder is included, which may result in additional costs and inconvenience later.
- Ignoring whether the CO₂ cylinder can be refilled locally, which may prevent the system from being used normally.
