Query: If you use an adapter....

I purchased both the horizontal and the vertical, after the horizontal fell off..still have both of them. What a crock, I hope they take them back. Bought locally, fortunately. After the filter gets heavy with water it just falls off in the sink when you go to turn it on. When you use the adapter it's suppose to just click into place and it does click but it will..., grrrrr, fall off, my experience anyway.
