Bests & Worsts Reviews from Amazon

Some of the negative reviews indicate that the Drinkwell is noisy. The truth is, it's only noisy if it doesn't have enough water or if the intake valve is clogged (which so far hasn't caused the pump to burn out for me). There's a slight hum from the pump when it's working correctly, but it will be much quieter than the other appliances in your kitchen. Cat hair and cat food can both clog the intake. So to keep it in top condition, check the water level once every day or two (or get the add-on reservoir), place the Drinkwell several paces away from the food dish (so your cats aren't tempted to moisten their food with it), and break down and clean the Drinkwell regularly, perhaps once a month when you change the filter cartridge.
