Possible Causes
Freeze damage from water left in PowerFlo housing over winter, Overtightened fittings stressing housing, Impact damage from tools or equipment, Aging and UV degradation of plastic housing
How to Fix / Troubleshooting
Safety first: Turn off power and isolate the pump by closing valves or plugging lines.
- Assess crack size: Small, non-pressurized hairline cracks may be temporarily slowed with epoxy, but this is not a permanent repair.
- Replace housing: The recommended fix is to replace the entire PowerFlo pump housing or wet end assembly. Transfer the motor, impeller, and seal to the new housing, or purchase a complete new pump if cost-effective.
- Winterize properly: To prevent recurrence, always remove drain plugs and fully drain the PowerFlo pump before freezing temperatures.
