Capacity, presentation and care
PetSafe Butterfly vs Creekside vs Outlast: capacity, water presentation and care
Three PetSafe fountains near the small end of this library have similar nominal volumes but put the pump and water in different arrangements. The Butterfly PWW00-16928 is 50 oz, the Creekside PWW00-17097 is 60 oz, and the Outlast PWW00-17957 is also 60 oz. Their labels do not predict how many days a bowl will last; refill needs depend on drinking, evaporation and the fill line.
Pick by water presentation and contact surface
The Butterfly is BPA-free plastic with a wide upper tray. Its removable topper provides four falling streams; without the topper, water bubbles across the tray. It runs continuously from a wall adapter, and PetSafe does not document adjustable pump speed. This is the smallest labeled volume of the three and the only one here with the butterfly topper.
The Creekside is a ceramic, 360-degree open-bowl bubbler with a submerged pump and continuous outlet flow. Its top-rack permission applies to the ceramic bowl and tower plus the plastic filter housing, not its silicone gasket, pump or adapter. Choose it when ceramic contact and an all-around approach matter more than a removable multi-stream topper.
The Outlast 60 uses a rotating wet cone above a separate dry motor base. Its design can make the water assembly easier to lift away from the electrical base during washing, but manufacturer materials reviewed for that model do not establish the bowl’s material grade. Do not label it steel or plastic from a photograph. It remains outlet-powered; a dry base does not mean cordless operation.
Compare the cleaning plan, not just the bowl
All three need regular level checks and hands-on cleaning. The Butterfly’s pump and adapter must stay out of the dishwasher; its manual gives separate carbon- and foam-filter replacement intervals. Creekside’s guide allows some large ceramic and plastic pieces on the top rack but excludes the silicone gasket and electrical parts. Outlast’s non-base water components lift from its dry base, but the base still needs protection from water. None removes the need to clean the pump or check the manufacturer’s exact assembly instructions.
For the smaller plastic fountain with optional falling streams, compare Butterfly. For a ceramic open bowl and bubbling tower, compare Creekside. For a 60-ounce bowl that lifts off a dry motor base, compare Outlast, while keeping the unconfirmed material out of any hard filter. If outlet-free placement is essential, none of these three qualifies: check the separately reviewed PetSafe HydroSphere Cordless or another model with an explicit battery operating plan.
