New Waste Ink Pump Assembly Cap Station for WF-3640 WF-3620 (NO RETURN)

Not a 5 difficulty! Would give it a 3. I watched the video and it came out perfect. I sanded and ran cart under faucet. I used Harbor Freight quick glue. I practiced a few times and used a lot of glue. Let it dry for 1 hour (30 seconds may have been enough) and filled. Made a mess when I used the plunger ( which I don't think was required). Dabbed with paper towel and put in printer. Worked perfect the first time. Really like the clear plastic cover so you can see how much ink in in the cart. Will be ordering more for my wife's printer at work.

BCH offers amazing quality products at very reasonable prices. I ordered the 4 ink 30ml kit and a larger black to refill my #62 HP cartridges. The videos are great and show how to easily refresh these wasteful cartridges and save a bunch of $. Thanks to Kevin and the team at BCH!

It was just what we needed. Thanks to your YouTube instruction I was able to order the part and fix my 83 yr old sister's printer. I am an 80 yr old female and was thrilled that this part fixed her printer and saved her some money since she did not have to buy a new printer. I have never before tried to fix something like this. Needless to say, I was surprised it work so well.
