Before You Buy
Key Buying Factors
01
Material Quality
Stainless steel is preferred over plastic to avoid scratches and bacterial growth. We look for food-grade 304 stainless steel.
02
Water Capacity
Larger capacity means fewer refills, especially for multi-pet households. We recommend 80 oz or more.
03
Pump Noise
Quiet pumps are essential for noise-sensitive pets. We test decibel levels and prefer pumps that can be fully submerged.
04
Ease of Cleaning
Fountains with wide openings and few crevices are easier to wash. Dishwasher-safe parts are a bonus.
05
Filtration System
Multi-stage filters (mechanical, carbon, ion-exchange) provide the best water purification. Replaceable filters should be readily available.
06
Safety Features
We check for low-voltage pumps, anti-dry-out protection, and non-slip bases. Cordless options are safer for chewing pets.
Living With It
Care, Cost and Maintenance
Daily Rinse
Rinse the fountain and pump under warm water every day to remove hair and debris. Prevents pump clogging.
Weekly Deep Clean
Disassemble all parts and wash with mild dish soap. Use a small brush to clean the pump impeller. Replace filter if needed.
Filter Replacement
Replace carbon filters every 2-4 weeks, and sponge filters every 4-6 weeks. Follow manufacturer guidelines for optimal water quality.
Pro tip
To minimize pump noise, ensure the water level is above the pump's intake and clean the impeller regularly. A quiet fountain encourages your pet to drink more.
Frequently asked questions
How often should I clean my pet fountain?
We recommend rinsing daily and doing a deep clean with disassembly once a week. Filter replacement varies by brand, typically every 2-4 weeks.
Is stainless steel better than plastic?
Yes. Stainless steel is non-porous, resists scratches where bacteria can hide, and is easier to sanitize. Plastic can develop microscopic cracks over time.
Can I use tap water?
Tap water is fine if your fountain has a carbon filter to remove chlorine and impurities. For pets with sensitive stomachs, filtered or bottled water may be safer.
How do I get my cat to use the fountain?
Place it near their regular water bowl at first, and ensure the flow is gentle. Some cats are attracted by moving water; try a trickling stream setting.
Why is my fountain pump making loud noise?
Loud pumps often indicate low water level, clogged impeller, or debris in the motor. Check water level and clean the pump thoroughly.
