Symptoms
- Water stops flowing or trickles weakly
- Pump makes noise but no water moves
- Pump doesn't turn on at all
Likely causes
- CommonDebris clogging the pump intake screenLeaves, algae, and sediment commonly block small fountain pump intakes.
- CommonWater level too low, causing the pump to run dryEvaporation can drop water below the pump intake, especially in summer.
- PossibleWorn out or failed pumpSmall fountain pumps have a limited lifespan, especially if run dry previously.
- PossibleTripped GFCI outlet powering the fountainOutdoor GFCI outlets can trip from moisture exposure.
What to do
- Check the outlet and reset any tripped GFCI before assuming a pump failure.
- Top off the water level so the pump intake stays fully submerged.
- Remove the pump and clean the intake screen and impeller of any algae or debris buildup.
- Run the pump in a bucket of clean water to test if it works independent of the fountain's plumbing.
- If the pump runs weakly or not at all in a clean water test, it likely needs replacement.
- Clean the fountain basin and tubing periodically to prevent recurring clogs.
Tools and parts
- Bucket (for testing)
- Soft brush (for cleaning)
