My cats love their Drinkwell Platinum Fountain. This is my second fountain. The pump would not operate on the 1st one after about 3 yrs even though I took it apart every other week and thoroughly cleaned it. My 2nd pump stopped working a couple days ago after I took the fountain apart and I started looking for a replacement pump. Thank goodness I saw your link to the YouTube video on cleaning the pumps. I knew to take the front part off, but never knew to take the inside apart. Well it is now midnight and after seeing this, I just had to try and see if it would work. It did!!! Now my cats are enjoying their running water once again. Thank you for such a great product!
We have had a Drinkwell Platinum Fountain for our cat for many years (the same one). I have had no problems with it since the day of purchase. I clean our the whole assembly every 2 weeks, including taking the pump apart and cleaning all the little parts. Scum will form in this pump, and in the base if you let it go too long. I believe this is one reason that we have had our fountain so long.
