A pet drinking fountain assembly having a pump forming part of a fountain mounting arrangement that includes a lift tube coupling a cover to the pump coupled to a lower basin by a mount. The mount and lift tube attenuate pump noise and vibration by providing isolation from the basin and cover and can function as dampeners. In a preferred embodiment the pump is part of a pump module that includes a module housing to which the pump is attached by another noise-attenuating mount. Each mount is formed by one or more suction cups with the cups and lift tube made of vibration dampening material, such as a resilient vibration dampening or isolating material that can be an elastomeric material. The module includes a lift tube coupling discharge that registers in fluid flow communication with a pump outlet and can include a ring or bushing therebetween providing additional noise attenuation.
