Poolaroo Pro Tip

When replacing the diffuser, inspect the impeller and shaft seal at the same time — these components wear together and are accessible once the pump volute is open. Replacing worn companion parts during the same service call avoids a repeat disassembly. Consult your pump's installation manual for torque specifications and O-ring seating requirements before reassembly.
