Hi there. Thanks for reaching out. You should be able to remove the reservoir by just pulling it out of the pitcher. If that does not work we recommend filling the pitcher up and putting soap and water around the edges. Once you have put soap and water around the top of the reservoir, turn the pitcher upside down in the sink. The pressure of the water should push the reservoir out. We hope this information was helpful. For further assistance, please contact us at 800-242-7482 and provide the following reference number: 181127-000625. We look forward to hearing from you.

The easy way to get the white part dislodged is this:
Remove the filter. Fill the pitcher all the way up with warm water and a dab of dishwashing liquid. Now turn it upside down. The force of the water and gravity will dislodge the white part. The soap adds some extra slip to dislodge things and cleans the pitcher.

It is might be hard to get the white thing out. Here is what you need to do. Empty the water and take the filter out. After that turn the entire thing upside down and with your fingers in, you should be able to pull it out. It worked for me and I hope it works for you. Please let me know.
Mine arrived yesterday and I saw all of these objections and, at first, I agreed that it could not be removed without extraordinary measures. But, there is a small round hole in the tunnel that holds the filter. If you have an implement with a hook -which I do - you put the hook into the hole and it comes right out. It is much quicker than any other method. Takes about two seconds.
Once I finally was able to remove the white reservoir from a very old pitcher, I experimented a little. By sticking my thumb in the spout and the side of my curled index finger inside the reservoir and then pulling straight up or up and slightly toward the spout, it came out fairly easily. Whenever I pulled up and toward the handle, it seemed like it locked it down more so.
It's actually very easy. Remove the filter. Fill the pitcher with not soapy water. Turn it upside in your sink. The weight of the water in the bottom of the pitcher pushes The white part right out. I tried it. It works!
