I have a drinkwell fountain and bought the 70 ounce resivior for it. When the resivior is attached the fountain overflows. Has anyone else ever had this problem? Does anyone have any ideas as to how to fix this problem? I am trying to figure out for sure if the resivior is defective or not before I call the internet retailer I bought it from. It should be easy to set this up but it is not working out. My hubby has washed my bathroom floor twice from the bowl overflowing.
