Frequently asked questions

Who is a large-capacity fountain best for?

It is designed mainly for large dogs, multi-pet homes and households that want more water available between refills. Actual refill frequency depends on pet size, number of pets, room temperature and drinking habits.

Why did the water flow become weak or stop?

Common causes include low water, debris around the impeller or intake sponge, and trapped air. Unplug the fountain before refilling, cleaning and reassembling it according to the model manual.

Why is the fountain louder than before?

Check the water level, pump position, impeller and intake for hair or mineral buildup. Also make sure the fountain is assembled correctly and resting on a level surface.

How often should I replace the filter?

There is no single interval for every household. Pet count, hair, water quality and the environment affect filter life. Follow the model manual and replace the filter when its condition or water flow indicates it is needed.

Can D2431 use the vertical cylindrical filters?

No. D2431 uses its own small square filter. The vertical cylindrical filter is for D2223, D2322, D2340 and the D2341 family.

Does one replacement pump fit this series?

Yes. Replacement pump SKU D2223-0USBK-N-02 fits D2223, D2322, D2340, the D2341 family and D2431.
