Before You Buy
Key Buying Factors
01
Material
Stainless steel is non-porous and resists bacterial growth better than plastic, reducing the risk of stomach upset.
02
Filtration System
Look for multi-stage filtration that removes impurities, hair, and debris to keep water clean and fresh.
03
Cleaning Ease
A fountain that's easy to disassemble and dishwasher-safe encourages regular cleaning, preventing biofilm buildup.
04
Water Capacity
Larger capacity reduces frequency of refills but ensure the fountain is not too large for your pet to access comfortably.
05
Noise Level
Quiet pumps are less likely to startle pets, encouraging regular drinking. Check decibel ratings in reviews.
06
Pump Reliability
A durable, submersible pump with low voltage operation ensures consistent water flow and long life.
Living With It
Care, Cost and Maintenance
Weekly Cleaning
Disassemble the fountain and wash all parts with mild soap and warm water. Rinse thoroughly to remove soap residue.
Filter Replacement
Replace filters every 2-4 weeks depending on water quality and usage. A dirty filter can harbor bacteria.
Pump Maintenance
Check the pump inlet for hair or debris monthly. Clean the pump impeller with a small brush to ensure smooth operation.
Pro tip
Even with a great fountain, change the water daily and give the bowl a quick rinse. Stagnant water can still cause issues, especially in warm climates.
