Quick answers
Before you send.
A few common questions customers ask before contacting support.
How often should I replace the filter?
Replace the DIANU filter and pre-filter sponge every 1-2 weeks for best results. Homes with multiple pets, hard water, or heavy daily use may need a faster routine.
How should I clean the fountain?
Unplug the fountain, empty the water, rinse water-contact parts with warm, soapy water, and check the pump path for hair or debris.
What should I include in my message?
Your order number, purchase channel, product issue, and a short description help support check the right purchase quickly.
