Frequently Asked Questions
Can I leave these dispensers outdoors year-round?
It depends on model and climate. Stainless steel, heavy-duty units (like PETSOLON) tolerate outdoor conditions best. Plastic gravity models can warp or retain odors in sun and may freeze in cold weather. In freezing climates bring dispensers inside overnight or use insulated/heated solutions.
How often should I clean the dispenser and replace filters?
Clean bowls and reservoirs weekly for multi-pet setups and more often if water looks dirty. Replace carbon and sponge filters according to the manufacturer — many recommend every 2–4 weeks under heavy use; pump sponges often need more frequent rinsing.
Is stainless steel worth the extra cost vs plastic?
Yes for hygiene and durability, especially outdoors or with many dogs. Stainless resists corrosion, is dishwasher-safe and less likely to retain smells. Plastic is lighter and cheaper but can stain, hold odors and degrade in sunlight over time.
