Safety: Turn off power and close valves or plug lines to prevent water flow before disassembling the pump.

Confirm leak source: Dry the area and observe. If water appears at the joint between the pump housing and motor, the mechanical seal is likely leaking.
Plan for seal replacement: Obtain a Zodiac-compatible seal kit for your specific pump model (includes mechanical seal and gaskets).
Disassemble wet end: Remove the pump housing bolts, pull the motor and seal plate assembly, and remove the impeller to access the seal. Note orientation of old seal parts.
Install new seal: Press the new ceramic seat into the seal plate and the carbon/spring half onto the impeller shaft, avoiding touching polished faces with bare fingers.
Reassemble and test: Reassemble the pump, restore water and power, and check for leaks.

If you are not comfortable with pump disassembly, have a pool technician perform the seal replacement.

Pump is leaking water from around the motor shaft area between the pump housing and motor.
