This was a pool that had a broken pressure gauge/air relief valve. The pool pump was also leaking. As you can see from the photos the corrosion on the pump motor is pretty severe. This was caused from the leak not being addressed properly.
The pressure gauge/air relief valve was replaced with a new heavy duty one. The pump was repaired to stop the leak but unfortunately the damage is already done and the life of this pump has been greatly reduced. Also you can see that the pump strainer basket is broken. These issues were unfortunately never brought to the homeowner by their pool service provider.
