About SIBAYS 4-Gallon Dog Water Fountain
This is the largest fountain in the group: a 15L (4 gallon) stainless steel unit with a water window, an LED that turns red when it is time to top up, dry-run protection per the listing and a pump listed under 25 dB. The listing gives 10 to 15 days between refills for a large dog or a multi-pet home.
The trade-off is upkeep. The listing says the filter should be replaced every 1 to 3 weeks, so it is worth pricing replacement filters before you buy, and a tank this size needs a dedicated spot.
