Before You Buy
Key Buying Factors
01
Capacity
Choose a fountain that holds enough water for your pet's needs. For large dogs or multiple pets, look for at least 3 liters. Larger capacity means less frequent refills.
02
Material
Stainless steel is our preferred material for its durability, ease of cleaning, and resistance to bacteria. Plastic fountains can scratch and harbor germs over time.
03
Filtration System
A multi-stage filter helps remove hair, debris, and impurities. Look for fountains with replaceable charcoal filters and foam filters to ensure clean, fresh water.
04
Noise Level
Fountains with submersible pumps are generally quieter. We recommend models with noise levels below 30 dB to avoid disturbing your pet's sleep or your household.
05
Ease of Cleaning
Regular cleaning prevents bacterial growth. Prioritize fountains with dishwasher-safe parts and wide openings for easy access to the pump and reservoir.
06
Flow Options
Some fountains offer adjustable flow rates or multiple drinking heights. This can cater to pets that prefer still water or need a lower drinking surface.
Living With It
Care, Cost and Maintenance
Weekly Cleaning
Disassemble the fountain and wash all parts with mild soap and warm water. Use a small brush to clean the pump and remove any debris from the filter sponge.
Filter Replacement
Replace the charcoal filter every 2-4 weeks, depending on water quality and usage. Some filters may need replacement more often if you have hard water.
Pump Maintenance
Periodically check the pump for clogs. Disassemble and clean the impeller and housing to ensure optimal water flow and reduce noise.
Pro tip
To minimize noise, ensure the water level is above the pump's minimum fill line. Also, placing the fountain on a level surface and cleaning the pump regularly can significantly reduce humming or vibration sounds.
Frequently asked questions
How often should I clean my pet water fountain?
We recommend a thorough cleaning at least once a week, including all parts and the pump. This prevents biofilm and bacteria buildup.
Can I use a stainless steel fountain for both cats and dogs?
Yes, stainless steel is safe for all pets. Multi-tier models are particularly good for households with both cats and dogs, as they offer different drinking heights.
Are these fountains dishwasher safe?
Many stainless steel parts are dishwasher safe, but check the manufacturer's instructions. Plastic components and pumps should generally be hand washed.
How long does a filter last?
Typically, charcoal filters need replacement every 2-4 weeks. Some fountains have indicator lights that remind you when to change the filter.
Will the fountain scare my pet?
Most pets adapt quickly to the sound of running water. However, start with a lower flow setting if available, and place the fountain in a quiet area to help your pet get accustomed.
