Please have the following ready when you call: Brand of motor (Askoll or Resun), Manufacture date of fountain (located on bottom of bowl). Why is my Drinkwell Platinum Overflowing?
The Platinum fountain is overflowing (not leaking) due to the reservoir not equalizing and emptying all of the water into the bowl. The Platinum would overflow only if air has access to enter freely. If air is entering the reservoir, the water will not equalize and the reservoir will begin to overflow the fountain. The way air would have access is if the reservoir is damaged, or if there is an air leak caused by a hairline fracture or crack in the reservoir plastic.
