    Supposed to be leakless...
  

*by L***G on Reviewed in the United States on June 21, 2024*

It's supposed to be a leakless water tank. Well it leaks from the bottom. And I can't for the life of me figure out how to get in touch with anyone to have them switch it out. So if you see this review could you please get in touch with me
