Before You Buy
Key Buying Factors
01
Water Capacity
Larger tanks (e.g., 108 oz) reduce refill frequency, ideal for multiple cats or owners with busy schedules.
02
Material Safety
Stainless steel is preferred over plastic to prevent bacterial buildup and avoid potential allergens.
03
Pump Noise
Look for pumps rated under 20 dB for quiet operation, especially if placed near sleeping areas.
04
Filter Quality
Multistage filters (pre-foam, activated carbon, ion-exchange resin) remove debris, odors, and impurities.
05
Ease of Cleaning
Wide opening and dishwasher-safe parts make maintenance simpler, reducing mold risks.
06
Cordless Design
Wireless pumps (like PETLIBRO) offer flexible placement and prevent chewing hazards.
Living With It
Care, Cost and Maintenance
Weekly Cleaning
Disassemble the fountain and wash all parts with warm, soapy water. Rinse thoroughly to remove soap residue. Use a small brush for the pump inlet.
Filter Replacement
Replace filters every 2-4 weeks depending on usage and water hardness. Signs of need: reduced flow, odor, or discoloration.
Pump Maintenance
Check the pump monthly for debris. Soak in a mixture of water and white vinegar for 15 minutes to remove scale, then rinse.
Pro tip
Place the fountain away from food bowls to prevent debris contamination, and use distilled water if your tap water is hard to reduce mineral buildup on the pump.
Frequently asked questions
How often should I clean my pet water fountain?
We recommend cleaning the entire fountain and pump weekly to prevent biofilm and bacteria growth.
Can I leave the fountain on all the time?
Yes, these fountains are designed for continuous operation. Ensure the water level never drops below the pump intake.
Is stainless steel better than plastic?
Yes, stainless steel is non-porous, resists bacteria, and is easier to sanitize. We prefer it for long-term use.
How do I reduce pump noise?
Ensure the pump is fully submerged and the water level is adequate. Also clean the pump regularly to prevent debris from causing noise.
What type of water should I use?
Filtered or distilled water is ideal to reduce mineral deposits and prolong filter life. Tap water is fine but may require more frequent filter changes.
