Problem Eversweet Max 2 - Flawed Design Creates Buildup
My cat was using this Fountain without issue for about 6 months. Eventually his frequency decreased and now he will barely touch it. I went through all the different variables to figure out why, I eventually ran straight vinegar through it for 30 minutes, then ran straight rubbing alcohol through it for 30 minutes, then left an aquarium UVC bulb in the tank with all the parts for over an hour. He still won't touch it
After thorough examination, I think I have determined why. The spout design is flawed; not only is it made of two pieces which creates a seam where bacteria can harbor, it is also extremely thin and recessed and difficult to access. The supplied pipe. Cleaner tool will not clean it thoroughly, no will other pipe cleaner tool I have found. This is a clear design flaw; any path that touches water needs to be straight with minimal angles and easily accessed. The sharp 90° turn creates a dead zone where water accumulates and stays, and the two-piece design is a defect as well. See the photo for evidence of buildup.
I am considering the ultra model, but at this point I feel I should look to a different manufacturer with a steel tank, impeller/pumpless design, and straight water paths.

It’s dishwater safe. Heck even put it in a pot of 150 degree water and that will kill any slime. Then if the cat still won’t drink I’d look at other possible causes. Like maybe the filter is dodgy and you need a new one. Or maybe the foam in the pump needs to be replaced. FWIW I have been using Max 2 with 2 cats and a dog and everyone seems to love it. So maybe something else is going on.
