PureSec-CMK01 Coffee Maker AutoFill Kit Filtered Water Auto Refill DIY Kit Coffee Machine Water Line Kit Direct Water Line Plumbing Kit For Non-Commercial Keurig Coffee maker Single-Serve Brewers

Used on a breville espresso machine, never have to fill it again and the family cannot run it dry!!

Got to love it. My Keurig is now filling itself and turning off automatically. Smooth operation a little scary drilling and a hole in the top of the water reservoir, but take your time drilling. It all turned out amazing.

The media could not be loaded. I been trying to find something like this for years! With the adaptor for the sink (see images Amazon) it was super easy to install.I did have to remove the float and step on it to fit, but it works amazing!! We will be buying another one for the downstairs flexbrew!!

Works great simple installNow more running out of water for coffee

I bought this before and I am about to buy it again for a different coffee maker. It works great. My only critique is that the line is blue. That color clashes with most kitchen setups. A black line would be best. Black valves would be great as well (if they even come in black). That way it would match the coffee maker much better and look nicer.

I used this to install a water line to my keurig coffee machine to always have water. The setup/install was very easy. No leakage or anything. Instructions were pretty good, but I followed a video of what someone else did to make sure I did it right.

Worked great for our Keurig.So nice not having to refill the tank anymore

I bought this kit in 2023 and it worked really well until my Keurig Coffee maker broke. So I bought a newer 2025 Keurig and tried to install the floater in the newer Keurig. Although I got the the floater to fit (barely) in a lid mounted configuration like I had done with my previous Keurig model, the new Keurig would stop at half a cup and the Add Water light would come on. As I experimented with the system it appears that the new Keurig models don't like to have the water reservoir being automatically refilled while the machine is dispensing a cup of coffee. This floater kit seems to mess up the Keurig's water metering system. I still intend to use the kit, but now I'll have to turn off the input water valve cock after the reservoir fills. Then I'll wait until the Keurig reservoir is empty before I turn the valve cock back on - only long enough to refill the reservoir. So the kit is still useful in that you don't have to refill the reservoir by removing it and taking it to the sink. But it is not the fully automatic refill system it used to be. I'll reiterate that this loss of automatic functionality is really due to the Keurig's new metering system rather than the kit. But it does make the kit less useful. If someone knows of a better way to solve this problem, I would really like to hear it.My original Review:This is really an easy DIY job. I give it 5 stars. What made this kit extra special is the inclusion of two tools not found in some of the other kits. The metal stepper drill bit tool is well made and really came in handy for drilling out a hole in my Keurig's lid so the float valve could be installed in the reservoir. The other really useful tool is the tube cutter used to make clean 90 degree cuts of the hoses. Good cuts make the tubing and adaptor mating perfect and worry free (no leaking thank you). 2 Tips: 1st Tip - Connect the Tee fitting to the output side of your refrigerator filter to feed filtered water into the coffee machine. Filtered water will keep the coffee machine cleaner and the coffee tasting better. Not only that, but every time you change the refrigerator filter you will have effectively changed the filter for the Keurig as well. 2nd Tip: Connect one of the 1/4" shutoff ball valves between the Tee fitting and the coffee maker where you can easily get to it. I put mine in the line feeding the coffee maker about a foot or so from the coffee maker so I can easily shut off the flow when I want to clean the reservoir.
