Step 1: Use the included drill bit to drill a 5/8" hole through which the mounting shaft fits. Step 2:You tighten the valve body into place with a plastic nut that compresses a silicon washer on the inside and a hard plastic washer on the outside. Step 3:Plug the 90-degree 1/4"elbow adapter into the valve body and stop when the elbow faced rearward Step 4: Insert standard 1/4"polyethylene tubing into the elbow until it reaches its stop. step 5: On the other end of the tube, you can fix a shutoff valve before the elbow. This allows you to turn the water off if you need to clean or decalcify the coffee maker or otherwise stop the water flow. step 6: If you want to split the filtered water into other appliance like refrigerator , you can add a tee adapter after the shut off vale and inst Review: Easy to Install! - Great product! The connectors for the valves and float switch were easy to install and work well. I had all the parts to connect to my fridge's water line, except the line is 5/16" OD with a 1/4" connector. This is a personal issue based on my fridge (many have 1/4" OD water lines which would work perfectly with this kit). Because of my unique situation, I had to buy a brass 1/4" Tee and a pig tail. This allowed me to attach the pig tail from the water source to the Tee; connect the braded 1/4" hose for the fridge water line to one side of the Tee; and connect the water line to the coffee maker on the other end of the Tee. When connecting plastic water tubing to a brass fitting (the other end of the Tee), ensure that you buy a tapered nylon compression sleeve fitting--very inexpensive, yet works better when connecting a plastic water line to a brass Tee. Again: this is a great kit; easy to install; and is very convenient! Review: Great product, all you need in one kit! - This kit is very easy to install. Everything you need in one kit. Remember, to keep from cracking the plastic on your coffee maker water reservoir lid, build up a stack of old cardboard and place under it when drilling. Use low drill force with the drill on high speed and the plastic will not Crack.

Also the top is easier to replace. With all the adjustment in the unit I don't see why not. I also bough the extra connectors and put a shut-off near the tee for the refig and one right behind the coffee pot. We have been using it for about three weeks and it is one of the BEST GADGETS it every got. **Q: Anyone used w/ k-duo plus?** A: We have a K-duo with a rear mounted water reservoir that fits the CMK01 easily. It appears from photos some of the K-duo plus have side mounted. Others rear mounted. Regardless, if either the width or length of the reservoir is less than 6" the auto-fill device likely won't have room to operate. It might need even more space if the reservoir lid is curved where the inlet fitting is mounted. Looks like depth won't be an issue. Hope that helps. **Q: Has anyone successfully used this kit with a Jura E8? I'm interested in trying it, but a little nervous given it requires drilling a hole.** A: Float is about 1-3/4" with ajustable angle . you can measure your water resevior firstly. if big enough, you can try. :) Drill a hole is very easy by using the included step drill bit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to Install! *by L***E on October 10, 2020* Great product!

Saves hours of re-filling *by A***R on November 3, 2025* Very affordable and completely worth it! It works well with an inline water filter with 1/4" quick connect tubing. No leaks or overflows in the elbows / shutoff valves / float after a few weeks of use so far. This saves countless minutes every day that add up to hours of standing at the sink waiting for filtered water to fill up a container that then gets poured into the reservoir. I was fortunate enough that the placement of the coffee maker was on an exposed wall from the basement side of the kitchen backsplash where the main PEX plumbing line was, making a hookup through the backsplash pretty easy with the right tools. You can also hook this up to your kitchen sink inlet area with the right 3-way adapter tee. It looks like a toilet shutoff valve but with a 1/4" quick connect tubing. You will need to drill a hole and have a bulkhead pass-through the sink area or drywall regardless of how you hook this up to a water line. Be mindful of local code and electrical wiring. I wouldn't suggest putting 1/4" quick connect tubing behind non-accessible drywall. Installing this in a K-Classic lid wasn't terribly difficult, though the step-bit included is quite dull. You will want a drill and a serrated knife or small saw to cut out a tiny notch you'll need on the hole perimeter after you drill out the hole, as the float has a keyhole notch to keep it from spinning around. I purchased a replacement lid and reservoir so as to be able to remove this in the future, as you will be drilling a hole in the lid. To find the right place for the hole, there are no instructions or templates, but with a marker and painter's tape it's quite easy to find the suitable spot so the float doesn't crash into any portion of the tank: - With the lid on the reservoir and viewed from the flat side, align the float at the lid-angle so the round end of the float has clearance to bob up and down without impacting the reservoir. You will be holding the float valve with your hand outside of the tank as if it were inside. Eyeball the small hole in the stem that will be sticking out from the lid from where you will connect the elbow and mark it on tape on the lid. This is your Y point. To find the X point: - With the lid off, tape a horizontal piece of tape over the open reservoir edges from side to side at the smallest part, where the area curves in like a backwards C shape, to the right over the edge. The center point between the backwards C and the | edge is the X point. Mark the lip on the left and right with a marker, as well as the center point. Peel the tape template off, put the lid on, and then tape it in the same spot on the lid itself. Take a ruler or eyeball straight up the X point to the Y point, and that's your drill hole mark. It should be somewhat center and at the top of the lid. In this way, the float should be centered with clearance in the X and Y planes of the reservoir. On a K-Classic, the tiny keyhole notch should be at the center bottom of the hole. Take your time with sawing out the small notch so it's a nice snug fit. ## Frequently Bought Together - 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 - Filtered Water Refill Do-It-Yourself Kit, For Non-Commercial Keurig Coffee Brewers by PureWater Filters - Keurig K-Duo Hot & Iced Single Serve & Carafe Coffee Maker, MultiStream Technology, 72oz Reservoir (Gen 2) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/187916558-cmk01-coffee-maker-autofill-kit-filtered-water-auto-refill-diy](https://www.desertcart.gr/products/187916558-cmk01-coffee-maker-autofill-kit-filtered-water-auto-refill-diy) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-19*
