Can You Run A Water Line To A Coffee Maker?

Certainly, you can connect a water line to a coffee maker.

Plumbed coffee makers are specifically engineered to link directly to a water source, eliminating the manual task of refilling the water reservoir.

Whether for commercial or home use, there’s a range of options available, including the Keurig K2500 Plumbed Single Serve Commercial Coffee Maker, among others featured in this article.

To set up a plumbed coffee maker, you’ll need a dedicated cold water supply line ideally situated beneath the unit or within approximately 4 feet of the machine.

It’s advisable to include a separate shut-off valve on the water line, which serves as a precautionary measure for emergencies, future maintenance, or servicing needs.

In compliance with local building codes, the water line should also feature a backflow preventer.

For comprehensive guidance and to ensure compliance with local regulations, consulting a licensed local plumber is strongly recommended.

They possess the knowledge of local laws and can provide the most reliable advice.

Why Choose a Plumbed Coffee Maker?

Opting for a plumbed coffee maker offers a range of benefits that cater to specific needs and situations.

These machines are directly connected to your main water supply, eliminating the constant need to refill a water tank.

Here’s why you might want to consider a plumbed coffee maker:

1. Convenience

The foremost advantage of plumbed coffee makers is the unmatched convenience they bring.

In environments with high foot traffic, like offices or coffee shops, the hassle of refilling the water tank is eliminated.

This ensures a seamless and uninterrupted coffee brewing experience, particularly in situations with numerous coffee enthusiasts.

2. Space Efficiency

By removing the water reservoir, plumbed coffee makers can be more compact, freeing up valuable counter space in your kitchen.

This can be a significant space-saving solution, especially for those with limited kitchen real estate.

3. Freshness

With a direct water connection, your brewing water doesn’t sit in a tank for extended periods, reducing the risk of it going stale or becoming a breeding ground for bacteria.

This guarantees that every cup of coffee you brew is as fresh as possible.

Important To Note:

However, it’s essential to note that plumbed coffee makers are typically found more in commercial settings due to their cost and reduced flexibility compared to standalone home coffee machines.

Prices for plumbed coffee makers can vary significantly, ranging from $300 to $10,000, depending on the model and additional features.

Therefore, when deciding whether to choose a plumbed coffee maker, it’s important to consider your specific needs, budget, and the scale of your coffee consumption.

Disadvantages of Plumbed Coffee Makers

While plumbed coffee makers offer undeniable advantages, they do come with some drawbacks that should be considered before making a choice.

Here are the disadvantages associated with plumbed coffee makers:

1. Water Quality Concerns

The primary drawback is the quality of the water running through the machine.

If your water supply has poor quality, it can significantly affect the taste of your coffee and, in extreme cases, might even pose health concerns.

The impurities in the water can compromise the flavor, and using unsafe water can be a real problem.

2. Descaling Necessity

Unless your plumbed coffee maker is equipped with a water filter, regular descaling is required to prevent contaminants in the water line from affecting the coffee’s taste.

Descaling can be a time-consuming task, and without it, the machine’s performance may degrade over time.

3. Higher Costs

Plumbed coffee makers tend to be more expensive compared to traditional countertop coffee makers.

Moreover, the installation process involves tools and plumbing knowledge, which could result in increased costs if you need to hire a professional for installation.

4. Risk of Leaks

The additional plumbing involved in plumbed coffee makers increases the risk of leaks, especially if you opt for a DIY installation.

A minor leak can lead to water damage, affecting both your machine and your kitchen.

5. Complex Repairs

While plumbed coffee machines are generally robust, any issues that do arise are often more complex and may require professional intervention.

This can lead to more significant repair costs and potential downtime for your coffee maker.

1. Keurig K2500 Plumbed Single-Serve Coffee Maker: Best Overall

Topping our list is the Keurig K2500 Plumbed Single-Serve Coffee Maker, and honestly, it was a close call between this one and its larger sibling, the K3500.

But when we compared them, the K2500 does have slightly fewer features.

However, it’s about half the price, making it a fantastic value for your money, especially for everyday coffee drinkers.

The K2500 offers many of the same features we liked in the K3500, including an easy-to-use full-color touchscreen, five cup size options, and brew-strength control.

This commercial coffee maker is tailored for small to medium-sized businesses, designed to work reliably day in and day out.

Plus, it comes with a direct water line connection for easy refills, reducing the need for constant top-ups.

The convenience doesn’t stop there.

Like most Keurigs, this machine uses K-Cups to brew single cups of coffee, tea, hot cocoa, and more.

While K-Cups may have environmental drawbacks, they’re incredibly convenient for office use, with a wide variety of flavors to satisfy everyone’s preferences.

The K2500 Commercial Coffee Maker is compliant with NSF-4 and ANSI cleaning and hygiene standards, ensuring it meets industry cleanliness requirements.

This plumbed coffee maker includes everything needed to connect it directly to your water line right out of the box.

However, if you prefer not to plumb it, you can purchase a separate kit that includes a large 110 oz water reservoir.

Users have praised this coffee maker for its ease of use, brew strength, and space-saving design.

Still, some have noted that it can be relatively expensive and a bit tricky to install.

We were also slightly disappointed not to have brew temperature control, as Keurigs tend to brew on the cooler side.

In our tests, we found the water temperature hovering around 185 to 195 degrees Fahrenheit, a bit below the ideal range.


  • Convenient direct water line connection
  • Affordable compared to its sibling, the K3500
  • Easy-to-use touchscreen interface
  • Multiple cup size options
  • Brew strength control
  • Ideal for small to medium-sized businesses

2. DRINKPOD JAVAPod K-Cup Coffee Maker: Best Budget Option

If you’re looking for a budget-friendly option, the DRINKPOD JAVAPod K-Cup Coffee Maker is a solid choice.

This single-serve brewer works with all K-cup pods and reusable capsules, or you can use the included paper filters for regular coffee.

It’s designed for simplicity, with pre-programmed settings to help you find the right size easily.

Brewing with this machine is a breeze – just pop in a K-Cup, and you’re good to go.

It takes less than 40 seconds to brew, and it automatically turns off after an energy-efficient 60 seconds.

The coffee maker comes in black and white and is a compact 7 inches wide, perfect for modern kitchens with limited space.

If you prefer not to plumb it, the 45-ounce water reservoir offers flexibility without the need for extra kits, a feature we found lacking in some Keurig models.

What’s great about this affordable machine is the added value it brings.

It’s versatile, handling French roast coffee, decaf, tea, cocoa, and more.

However, customization options are limited – choose between 6, 8, and 10 ounces.

While a 12-ounce option would be nice, brewing 6 ounces twice works as a workaround.

Another downside is that given its budget nature, durability can be a concern.

Keep this in mind if you’re considering this coffee maker.

Overall, it’s a straightforward, budget-friendly option with some limitations but offers excellent value for the price.


  • Budget-friendly option
  • Compatible with K-Cup pods and reusable capsules
  • Simple and pre-programmed operation

Its clean lines, sleek design, and full-color touchscreen display lend it a modern and professional appearance well-suited for business settings.

It’s also NSF-certified and comes with a 1-year limited warranty.

Keep in mind that the K3500 is designed to be plumbed for automatic water refill, but you’ll need to purchase the plumbing kit separately.

What sets it apart? Well, it’s pretty smart.

This self-filling coffee wizard expertly showers your coffee grounds with hot water at just the right temperature for a delightful brew.

It can brew up to 10 cups, and you’re in control with the adjustable cup selector, allowing you to make as much or as little coffee as you fancy.

Now, why’s it so special? This coffee maestro adheres to the Specialty Coffee Association of America standards for top-tier brewing.

The Brew Trak® system ensures that it maintains the perfect brewing temperature, regardless of your water’s temperature or any voltage fluctuations.

It even boasts a fancy showerhead-style water distribution, making sure every coffee ground is evenly soaked, which means you get the best extraction each time.

And no worries about a lukewarm brew! The thermal carafe keeps your coffee piping hot without ruining its delicious flavor by overheating it on a warming plate.

And the best part? It’s built to last, so you can count on years of coffee joy.

It’s not just a time-saver; it brews in half the time of those regular machines.

We clocked it at less than 9 minutes for a full 10-cup batch, including the initial heat-up time.

Plus, it’s equipped with an infrared sensor that lets you safely remove the carafe during brewing without any spills.

But, no product is perfect. What could be better? Well, we adore its design, but it would be nice to see a little less plastic in its construction, especially given the price.

And if you’re into single servings, you’ll need an extra adapter, which feels like an added cost on an already pricey machine.


  • Elegant stainless steel design
  • Self-filling for convenience
  • Customizable brewing with an adjustable cup selector
  • SCA-compliant for high-quality coffee
  • Consistent brewing temperature and even saturation
  • Thermal carafe keeps coffee hot without overheating
  • Programmable timer/clock for convenience


  • More plastic in the build than expected

It’s worth noting that it’s UL commercial listed and NSF certified, ensuring it meets the standards for use in food service outlets.

However, there are some limitations to consider.

If you want the convenience of a dedicated water line, you’ll need to purchase the direct plumb kit separately, incurring an additional cost.

Also, this coffee maker is not compatible with standard reusable K-Cups, so if you prefer using those, it might not be the best fit for you.


  • Interactive touch-screen for customized brewing
  • Removable 90 oz. water reservoir reduces refilling
  • Accommodates various brew sizes
  • Versatile with access to over 400 beverages

6. BUNN My Cafe MCO Single Serve Commercial Automatic Brewer: Best For Offices

The BUNN My Cafe MCO is another NSF-certified powerhouse designed for commercial settings.

It’s similar in size and price to the Keurig K3500 but boasts some cool features that set it apart.

Just like the Keurig, it’s a single-serve brewer that works with K Cups, ensuring everyone gets their preferred beverage.

The BUNN My Cafe MCO Single Serve Commercial Automatic Brewer is your go-to solution for serving up top-notch coffee in a jiffy.

It’s tailor-made for offices and small businesses.

The brewer comes with a user-friendly touchscreen interface, letting you select your brewing settings for coffee, tea, cocoa, or hot water.

In a nutshell, the BUNN My Cafe MCO Single Serve Commercial Automatic Brewer is a reliable, efficient, and quick solution to brew single servings of coffee and other hot drinks for your guests.

However, it’s worth noting that this coffee maker comes with a higher price tag, and it doesn’t include a reusable K Cup for ground coffee, which might be a drawback for some.


  • Touchscreen interface for easy operation
  • Versatile brewing with multiple beverage options and sizes
  • Quality brewing with unique water jet extraction
  • Energy-efficient with an idle mode

7. Waring Commercial WCM70PAP Café Deco: Best For Brewing Multiple Cups

The Waring Commercial WCM70PAP Café Deco is an automatic airpot coffee brewer, built for high capacity.

This workhorse can churn out a whopping 4 gallons of coffee per hour, which translates to around 64 8-ounce cups per hour.

It’s specially designed to accommodate large airpots and even has a separate faucet for hot water, perfect for making tea, soup, or other hot beverages.

Now, here’s the deal: this coffee maker keeps it simple.

No fancy customizations, and it doesn’t use coffee pods. Just pop in your ground coffee, hit the brew button, and you’re good to go.

It’s constructed with tough stainless steel, built to withstand the test of time.

You’ll find handy features like a push-button brew start, ready and power indicator lights, and an ultra-efficient 18-hole spray head that can be easily removed for cleaning.

One thing to note is that this plumbed coffee maker skips the “bloom phase,” which can sometimes result in a bit of a messy spray when the water meets the coffee grounds.

But don’t worry, a quick pre-spray of the grounds before placing the basket in the machine can solve this issue.

Although, it would be nice if Waring addressed this in future models.

This unit is plumbed, meaning it needs a direct connection to your plumbing for automatic refills.

It’s got the safety checkmarks with NSF listing and TUV certification, and it comes with a 6-foot power cord with a NEMA 5-15P plug.

In terms of size, it measures 8 inches in width, 17.5 inches in depth, and 25.8 inches in height.

Keep in mind that the airpots are sold separately in 2.2 L and 2.5 L sizes, so you can choose the one that suits your needs.

Or, if you prefer, you can explore other coffee pot options from different brands and styles.

Just a heads up, this brewer is designed to brew into an airpot, but, surprisingly, it doesn’t come with one included despite its relatively high cost.

  • Easy-to-clean 18-hole spray head
  • Safety certifications: NSF-listed and TUV certified

Buyer’s Guide: How to Choose the Best Coffee Maker with Water Line

When it comes to selecting the ideal coffee maker with a water line connection, several factors must be considered to ensure you make the best choice.

This comprehensive guide will walk you through the essential aspects to help you find the perfect coffee maker for your specific needs.

Brewing Capacity

The first and foremost consideration is the brewing capacity of the coffee maker.

Determine how much coffee you need to brew in a given time frame.

Coffee makers with water lines come in various sizes, so choose one that aligns with your daily or event-specific requirements.

Smaller models may be suitable for home use, while larger ones are ideal for commercial settings, like offices or restaurants.

Brew Time

The time it takes for the coffee maker to brew a pot of coffee is crucial, especially in busy environments.

Look for a coffee maker that offers a balance between speed and brew quality.

While you want your coffee fast, you don’t want to compromise on taste.

Some coffee makers may offer quick brewing times, which can be a key factor in time-sensitive situations.

Water Connection

The heart of a coffee maker with a water line connection is its plumbing compatibility.

Ensure that your coffee maker can connect directly to your water supply or plumbing system.

This feature eliminates the need to manually refill water tanks, making the brewing process seamless and efficient.

The plumbing connection should be easy to set up and maintain.


Consider the programmability options of the coffee maker.

Can it be set to start brewing at specific times, making sure your coffee is ready when you need it?

This feature is valuable for both homes and businesses, as it can save time in the morning or have a fresh pot ready for customers when your business opens.

Brewing Options

Determine the variety of brewing options available.

Some coffee makers offer multiple cup size selections, strength control, or temperature adjustments.

These features allow you to customize your coffee to suit different tastes.

Ensure that the coffee maker can cater to the preferences of everyone who will be using it.

Maintenance and Cleaning

The ease of cleaning and maintenance is essential.

Coffee makers with detachable components and dishwasher-safe parts simplify the cleaning process.

Look for models with features like automatic cleaning cycles or descaling functions to maintain the machine’s longevity.

Size and Space

Consider the physical dimensions of the coffee maker and the space available in your kitchen or workplace.

It should fit comfortably on your countertop without causing overcrowding.

If space is limited, choose a compact coffee maker to maximize available room.

Water Quality

The quality of your water supply is important.

Ensure that your water source is filtered or treated to prevent mineral buildup in the coffee maker.

If your water is hard, it might be beneficial to invest in a coffee maker with a water softener or built-in filtration system.

Brand and Model Reputation

Research different coffee maker brands and models to find ones with a reputation for quality and durability.

Read reviews and consider recommendations from others who have used the same machine to ensure reliability and customer satisfaction.

Price and Budget

Coffee makers with water line connections vary in price.

Determine your budget and find a model that meets your requirements without overstretching your finances.

Keep in mind that while a higher upfront cost might seem daunting, it can pay off in the long run with reduced maintenance and improved efficiency.

Plumbed Coffee Maker vs Plumbing Kits

When it comes to connecting your coffee maker to your water line, you’ve got two choices to consider.

You can either opt for a built-in coffee system designed to seamlessly plumb into your water supply, or you can go for a coffee maker water line kit that’s adaptable and can be installed with most coffee maker brands.

The coffee maker water line kit takes a do-it-yourself approach, creating a direct link between your coffee maker and the water line.

It’s a flexible and cost-effective solution for many.

On the flip side, built-in coffee systems offer a sleek and modern appearance that can be customized to match your specific needs.

They’re versatile in terms of placement within your kitchen, freeing up valuable counter space for other small appliances.

However, it’s important to note that these built-in systems can be quite expensive, and their installation demands careful consideration.

Many consumers, in pursuit of a practical and budget-friendly solution, choose to retrofit their existing coffee maker with an after-market plumbing kit rather than investing in a high-cost plumbed machine.

Ultimately, your choice between a plumbed coffee maker and a plumbing kit hinges on your personal preferences, budget constraints, and lifestyle requirements.

How to Descale Your Plumbed Coffee Maker

Descaling your plumbed coffee maker is a crucial maintenance task that keeps your machine in excellent shape and ensures your coffee remains top-notch.

Here’s a straightforward step-by-step guide on how to descale your plumbed coffee maker:

1. Power Off and Unplug:

  • Begin by turning off your coffee maker and unplugging it from the power source.

2. Remove the Water Line:

  • Carefully disconnect the water line from the water source.

3. Submerge in Descaling Solution:

  • Submerge the disconnected water line into a pitcher filled with descaling solution. You have the choice of using plain white vinegar or a commercial descaling solution.

4. Heat the Machine:

  • Allow your coffee maker to fully heat up.

5. Flush the Machine:

  • Pull about 8 oz of the descaling solution through the group and another 6-8 oz from the hot water wand.

6. Let It Sit:

  • Give your machine a bit of rest. Let it sit for approximately an hour.

7. Repeat the Process:

  • Repeat the flushing process every hour until the pitcher is empty.

8. Drain the Boiler (If Applicable):

  • For machines with boiler drains, allow the machine to cool down and then open the drain plug to release any water in the boiler. Don’t forget to close and seal the drain plug afterward.

9. Release Steam Pressure (If No Drains):

  • In the absence of drains, turn off your machine and open the water wand to release any remaining steam and water pressure.

10. Rinse with Fresh Water: – Refill your pitcher with fresh water and repeat the flushing process until the water runs clear and smells clean.

11. Thoroughly Rinse: – After completing the descaling process, ensure you rinse the machine thoroughly with fresh water.

12. Reconnect and Plug In: – Reconnect the water line to the water source and plug your machine back in.

Remember, it’s advisable to descale your plumbed coffee maker every few months, considering your usage frequency and water hardness.

Regular descaling keeps mineral buildup at bay, maintaining your machine’s efficiency and extending its lifespan.

Each of these coffee makers with water lines has its unique strengths, catering to different preferences and requirements.


What is the primary advantage of a plumbed coffee maker over traditional models?

A plumbed coffee maker’s primary advantage is the direct connection to your water supply, eliminating the need to refill the water tank.

This ensures a constant supply of water, making it ideal for high-traffic environments like offices or coffee shops.

Are plumbed coffee makers suitable for home use, or are they mostly for commercial settings?

Plumbed coffee makers are commonly found in commercial settings due to their cost and reduced flexibility compared to standalone home coffee machines.

However, there are options available for home use, though they may be limited and pricier.

What should I consider when choosing between a plumbed coffee maker and a plumbing kit for my existing machine?

The choice depends on your preferences, budget, and lifestyle.

Plumbed coffee makers offer convenience and space efficiency but can be more expensive.

Plumbing kits can retrofit your existing machine, offering cost-effectiveness and flexibility.

Are there water quality concerns with plumbed coffee makers?

Yes, the water quality in your area can affect the taste of your coffee when using a plumbed machine.

If your water has impurities, it can compromise the flavor and even pose safety risks.

A good filtration system or regular descaling can mitigate this issue.

What are the key maintenance considerations for plumbed coffee makers?

Regular descaling is essential to prevent contaminants in the water line from affecting your coffee’s taste.

Additionally, addressing any leaks promptly and ensuring professional repairs when necessary are crucial for long-term maintenance.

Can I install a plumbed coffee maker by myself, or do I need a professional plumber?

The complexity of installation can vary.

While some individuals with plumbing knowledge may handle it themselves, hiring a professional plumber is recommended for a seamless and safe installation, as well as to comply with local building codes.

Can Nespresso Machines Be Directly Connected To Water Lines?

Yes, Nespresso machines can indeed be directly connected to water lines.

You have a variety of options to achieve this connection, including the use of a plumbing kit, a water connection kit, or an inline water filter kit.

Notably, some Nespresso machines, like the Nespresso Momento 100, are specifically designed for direct connection to a water network.

To ensure a smooth and effective installation, it’s crucial to follow the manufacturer’s instructions and guidelines provided for both the coffee machine and the chosen water line kit.
