PRO TIPS
- This pump has an integrated diode, which means polarity matters on some control circuits, if it hums but won't push water after a swap, double-check your wiring orientation before assuming the pump is defective.
- Never let this pump run dry or feed it water above 20°C, both are common causes of premature vibratory pump failure, and neither is covered as a defect.
