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

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.

Everyone should have one of these. Was fairly easy to install and we never have to put water in our keurig. Just remember to take the container off and clean it once in a while.

Love this product! The kit is complete with all the necessary fitting and all of the parts seem good quality. I installed it in my Ninja CFN601 with one valve about two inches from the reservoir (easy access) and one valve upstream of the tee. It took a minute to figure out the positioning because the reservoir has molded hand grips that could interfere with the float, depending on the location of the valve on the reservoir cover and the axial rotation of the valve. With careful alignment it fits just fine. That said, installing the shutoff valve to be accessible from the countertop is critical- in case the float binds. The valves and fittings are John Guest-type fittings, which are superior to compression fittings and leak resistant when moved/bumped. I was trying to piece together a kit like this using brass parts, but this works well and is probably better than any kit I could have cobbled together.

Easy install, includes everything needed. And works. No issues yet.

2 Year Update: this is still going strong. We love this and now we can't imagine having to fill the coffee maker! Having this has allowed us to create a coffee nook out of a fairly narrow cabinet space when we remodeled our kitchen since we don't need frequent access to the back of the coffee maker anymore.Original review:Works great on our Ninja CP301 with a slight modification. There is a tab at the top of the reservoir that indicates the max water level that we needed to cut off in order for the float to completely rise. Not a ton of room to work with in the Ninja, but it is doable for sure, just need a little hacksaw! I'm including a couple of pics to show placement. We also taped down the lid with electrical tape as other reviews suggested. So happy that this works!!! We are not K cup people and I had only found one coffee maker that is designed for direct line water...but we love our Ninja - this is EXACTLY what we needed! We bought longer tubing since we wanted to keep our coffee maker where it is at and not move it next to our fridge. We luckily have an unfinished basement, so we teed off of the line to the fridge below deck and came up through the floor and through the cabinet. Even drilled a little hole in the granite countertop for a nice clean install. This kit is a winner!

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!!

Just like the other reviews, this did not arrive with instructions. A little mechanical/plumbing knowledge/skill and a drill are needed for installation. The quality of the parts are good and it works like a charm.

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.
