Setup and Installation
Follow these steps to properly install your new PETLIBRO Dockstream replacement filter:
- Prepare the Filter: Before first use, soak the new filter in a clean bowl of water for 5 minutes. This helps to remove any loose carbon dust and ensures optimal filtration from the start.
- Rinse the Filter: After soaking, rinse the filter thoroughly under running water for 30 seconds.
- Install Pre-filter Sponge: Insert the pre-filter sponge into the designated slot on the water pump.
- Assemble Pump and Silicone Tube: Attach the silicone tube to the water pump.
- Place Filter: Place the prepared filter into the filter tray of your PETLIBRO Dockstream fountain. Ensure it is seated correctly.
- Fill Water Tank: Fill the fountain's water tank to the appropriate level.
- Secure Lid: Place the water bowl and secure the top lid of the fountain.
- Align and Power On: Install the water container onto the base, aligning the protruding hole of the water container with the base. Turn on the power switch on the base (Induction Mode) or connect to power (Continuous Flow Mode).

Operating Principle
The PETLIBRO Dockstream replacement filter utilizes a 4-layer filtration system to provide fresh and clean water for your pet:
- Non-woven Fabric: Captures hair, debris, and other larger impurities.
- Activated Carbon: Eliminates bad odors and tastes from the water.
- Ion Exchange Resin: Removes heavy metal ions and softens water quality.
- Sponge: The integrated pump sponge further filters dirt to prevent blockages and damage to the pump.

Maintenance
Filter Replacement
To maintain optimal filtration effect and ensure your pet's health, it is highly recommended to replace the filters every 2 weeks. Always use official PETLIBRO replacement filters.

This image emphasizes the recommended filter replacement schedule, advising users to change filters every two weeks to ensure optimal water quality and pet health.
Pump Cleaning
Regular cleaning of the pump is crucial for extending its lifespan and ensuring continuous water flow. It is recommended to disassemble and clean the water pump every 14 days.
- Remove Pump Cover and Impeller Cap: Carefully detach the pump cover and the impeller cap.
- Remove Impeller: Gently pull out the impeller.
- Clean Components: Use the provided cleaning brush to thoroughly clean all pump components, removing any hair, debris, or mineral buildup.
Troubleshooting
Pump Clogging or Reduced Flow
If you notice reduced water flow or the pump appears to be struggling, it is often due to a clogged filter or pump. Ensure you are using official PETLIBRO filters, as unofficial filters may not fit correctly or may not provide adequate filtration, leading to pump issues.

This visual comparison demonstrates the importance of using official PETLIBRO filters. Unofficial filters are shown to potentially cause pump blockages, whereas genuine filters ensure smooth operation.
Water Quality Issues
If the water does not appear fresh or clean, ensure the filter is replaced regularly (every 2 weeks) and that the fountain and pump are cleaned thoroughly during each filter change.
