The pool pump is leaking and making a whining nose
The pump is leaking between the turbine housing and motor on the bottom .
Welcome to JA! The leak is caused from the pump seal mounted on the shaft that went bad. The whining may be the bearings in the motor going out. If the pump is less than 5 Years old, it may be worth rebuilding, otherwise probably time for a new pump.
