A pet water fountain keeps water circulating and encourages pets to drink more—but like any small appliance it can run into issues. Below are the most common problems and proven fixes so you can keep your pet's fountain running smoothly.
If the fountain stops entirely, begin with the basics: check power and inspect the pump. Many pumps stop because of clogs (hair, food debris) or because they ran dry and burned out.
Unplug the unit, remove the pump, rinse and clear debris from the impeller and intake. If cleaning doesn't help, most manufacturers sell replacement pumps. For step-by-step cleaning instructions for common models, see PetSafe's cleaning guide.
Loud grinding or rattling is usually caused by the pump drawing air (low water level), debris in the impeller, or mineral buildup.
Keep water above the minimum fill line; clean or soak pump parts in vinegar to remove calcium/mineral deposits; place the fountain on a rubber mat to isolate vibration. PetSafe notes recommended cleaning intervals and techniques for avoiding noisy pumps. Learn more.
A weakening stream commonly points to a clogged filter, misaligned pump, or internal scaling that reduces pump efficiency.
Replace or clean filters every 2–4 weeks depending on usage and water hardness; check that the pump is seated correctly; perform a vinegar soak on pump parts to remove mineral scale. Regular filter changes and pump maintenance help restore proper flow. More hydration tips.
Cloudiness, slime, or an off smell usually means biofilm, bacterial growth, or algae (if the fountain is in sunlight).
Wash every removable part weekly with warm soapy water, scrub corners and pump housings where slime accumulates, and rinse thoroughly before refilling. Avoid direct sunlight to limit algae growth. Daily freshening and weekly deep cleaning keep water safe and appealing for pets; animal welfare organizations recommend providing fresh, clean water and washing bowls regularly.

If the fountain works but your pet avoids it, the issue may be placement, noise, or unfamiliarity rather than a mechanical fault.
Move the fountain to a quiet, accessible spot away from food and litter boxes; keep the water cool and change it frequently; introduce the fountain gradually—put it near the old bowl so your pet notices it. Encouraging hydration is especially important in warm weather and for pets with certain health needs. PetMD hydration tips.
Top up water so the pump remains submerged.
Disassemble and wash all removable parts (pump, bowl, spouts).
Replace or deep-clean filters and inspect pump seals.
Replace pump if performance declines or if repairs aren't lasting.
PetMD and veterinary sources recommend routine care and checking local water quality (tap water mineral content can affect buildup). Is tap water safe for dogs?
Consider replacing the fountain if: the pump repeatedly fails after cleaning, the reservoir has cracks or leaks, or the unit is several years old and parts are no longer reliable. Newer models often have quieter pumps, easier disassembly, and standardized filters that simplify maintenance.
Pro tip: If your fountain is more than 2-3 years old and requiring frequent repairs, investing in a new model will often save you time and frustration in the long run.
Most fountain problems are resolved with regular cleaning, timely filter changes, and simple checks (water level and power). I validated the resources used above so each external link in this post is live and relevant—click any citation in the article to open the source.
