Choose a configuration

Viva: choose capacity, drinking surface and care

The Viva family has three documented US configurations, so choose the capacity and drinking surface as a real combination. A generic product title, a photograph of another size or the word “stainless” is not enough to identify the fountain in the box.

I want the smaller plastic version

The 64 oz plastic PWW00-17919 supplies the smaller reservoir and a plastic drinking tray. Its nominal capacity converts to about 1.89 liters in US fluid units. It suits someone whose routine does not need the larger stored volume and who is comfortable with the plastic surface.

This setup still needs an outlet, a clean pump and replacement filters. The smaller reservoir is not permission to ignore the water between cleanings. Check the window, the water and the operating condition directly, then refill to the marked line as needed.

I want steel where my cat drinks

The 64 oz steel-tray ZWW00-17921 changes the drinking surface while retaining the named 64 oz capacity. The steel claim concerns the tray; it does not describe every wet component or move the motor into a dry base. Choose it because that particular contact surface is useful to you.

The current US selector offers the steel tray with the 64 oz reservoir. It does not show a 140 oz steel-tray combination. If you want both more than four liters of nominal capacity and a steel drinking surface, neither selecting the largest Viva nor selecting “stainless” on a generic listing establishes that combination.

I want more water in the same general routine

The 140 oz plastic PWW00-17922 provides approximately 4.14 liters in nominal US fluid units, more than twice the 64 oz amount. The larger reservoir can be useful at a busier drinking station, but consider emptying and handling the larger bowl as well as refilling it.

All three use the documented outlet-powered bubbling arrangement and a flow-control knob on the pump. Larger capacity does not add battery operation, pet identification or intake records. If outlet-free placement matters, compare a documented battery model such as HydroSphere Cordless, while recognizing that its battery flow uses a sensor rather than continuously circulating water.

Which parts go in the dishwasher?

The shared Viva guide permits the bowl, pump housing and tray on the top rack. The pump is opened and hand cleaned; the adaptor stays out of the dishwasher. A requirement for dishwasher permission on the drinking tray is therefore different from wanting to put the complete assembled fountain into the machine.

PetSafe's normal guide is cleaning every two to four weeks, with more frequent attention as needed for multiple pets. Replace the carbon-and-ion-exchange filter every two to four weeks and the foam filter every one to two months. Keep soap out of the filter pieces. None of those intervals becomes twice as long just because the reservoir holds more than twice the water.

What does the light tell me?

The blue LED indicates the powered pump, and red accompanies low-water shutdown. The guide says the pump restarts after a refill. This helps with a local refill check; it does not tell you which cat drank or how much. Match the actual capacity, surface and care routine first, then select a different documented feature set if you need records, a dry motor base or battery placement.
