What Keurig Brewers Can Be Connected to a Direct Water Line?

I get this question a lot from people who are sick and tired of manually filling up their Keurig’s water reservoir after every handful of brews. It’s MUCH easier (not to mention time-saving) to simply have your water tank automatically refill each time it gets low on water. So, the question people often ask me is:

Which Keurig brewer models are compatible with the various Plumb Kits and Direct Water Line Filter Kits on the market?

The short answer is: all of them. The real question you should be asking, however, is whether or not your particular Keurig brewer model is compatible with what’s called a Direct Water Line Plumb Kit. If so, congratulations! The installation process will be a whole lot easier for you.

What is a Direct Water Line Plumb Kit?

Essentially, the Plumb Kit, as it’s called, is really just a fancy mechanical water reservoir (yes it replaces your existing reservoir) which contains built in plumbing gadgets, such as water float valves, etc., that allow you to hook your Keurig Coffee Maker directly into your home or office’s water supply in order to automatically refill the water reservoir on your Brewer.

So What Keurig Brewer Models are Compatible with the Direct Water Line Plumb Kit?

Not all brewer models are compatible with the Plumb Kit. Only the following Keurig brewers are are compatible:

As you might notice, Keurig only made its Plumb Kit compatible with the more “commercial” type brewer models. Keurig does not currently offer a Direct Plumb Kit for the Keurig 2.0, Classic, or other similar “home” market segment brewers.

Once you have the Plumb Kit, you will also need this Keurig Water Filter Kit to complete the process.

UPDATE: Keurig has recently stopped manufacturing the Plumb Kits, and are beginning to phase out the K150/B150 model brewers altogether. Replacing these brewers is their new plumbable version of the K2500 model which does not require a separate Plumb Kit reservoir (good news!). If you have the Keurig K2500 brewer, you will only need this Direct Water Line Filter Kit.

However, if your brewer model is not listed above, don’t fret. This does not mean you cannot connect your brewer to a Direct Water Line. In fact, there is now a handy Do It Yourself Filter Kit on the market which allows you to do just that. It also has the added bonus of filtering your water too!

I purchased one of these for my Keurig 2.0 brewer a few weeks ago and I love it. It allows me to fill my water reservoir with the flip of a switch, without having to take any trips to the sink. I plan to add a new blog post detailing the installation process for those of you like me who do not have a commercial brewer.

I will update soon.

  1. Larry

    I am interested in the k-elite single cup what water line kit can I use?

    1. John

      Hey Larry, this water line kit is what you’d need for your Keurig K-Elite (K90) brewer, but note that you’ll have to drill a small hole in the water reservoir to install it.

  2. Sarah

    Can we get the water line hooked to a K-Duo Plus??

    1. John

      Hey Sarah, the K-Duo brewer can’t be connected to a direct water line using the standard Plumb Kit option, but if you are a bit handy you can use something like this Do-It-Yourself Filtered Water Kit, but note that you will have to drill a small hole in your Keurig’s water reservoir to do this.

  3. Heather

    Remodeling kitchen. Want to link Keurig to waterline. Do I need a “hole” in countertop for water hose to go thru to couple?

    1. John

      Hi Heather, great question! Normally, no you don’t need to drill a hole. This will largely depend on what you are using as your water supply to the brewer. If your supply is only accessible from under the counter (under-sink connection, etc) then you would probably need to drill a hole. Otherwise if the machine is close enough to the water supply, such as next to the refrigerator, you can simply run the line from behind the counter. This is what most people do.

  4. Robin

    Is the Keurig Duo able to be plumbed directly to the refrigerator water line? Or do we need to buy the 150P?

    1. John

      Good question Robin. See my answer to Sarah’s question above. I would recommend going with the K150P if you want the easiest installation and set-up for direct water line hookup.

  5. Liz

    I am looking at a Keurig K-Cafe Special Edition Coffee Maker for an office (about 20 people) and am looking to do the aftermarket direct water line conversion kit. Will this work?

    1. John

      Hey Liz, yes the Do It Yourself Filter Kit option referenced above will work with your brewer. Note that since it’s not directly built into the brewer, it isn’t the most elegant but the water line does tuck away quite nicely behind the brewer and you can’t beat saving those trips to the sink!
