Possible Causes

How to Fix / Troubleshooting
Safety first: Turn off power and close isolation valves. Allow the pump to cool before disassembly.
- Confirm leak location: Look for water dripping from the joint between the Aquaflow wet end and motor, not from plumbing unions.
- Inspect unions: Tighten suction and discharge unions to rule out plumbing leaks.
- Plan seal replacement: Mechanical seal replacement requires separating the pump housing from the motor, removing the impeller, and installing a new Aquaflow mechanical seal kit.
If you are not comfortable disassembling the pump, have a technician replace the seal and inspect the motor bearings for water damage.
