The PetSafe® Drinkwell® Everflow Pet Fountain allows your pet access to a constant supply of fresh water. When used outdoors, the fountain connects to a standard garden hose and automatically refills to the desired water level preset by the pet’s owner. When used indoors, the Everflow holds 192 oz. of water. The fountain continuously circulates and filters the water, keeping it cleaner and fresher than a normal water bowl. Trust PetSafe® to help keep your pet healthy, safe and happy.
