We recently bought a house and the pool with house was not in great shape. Probably not used for 2-3 yrs. after fixing the pool we found out the pump won't start. I have attached the pic of the part where it shows a loose connection. I have no electrical knowledge and wanted to ask you all experts if this rusted end can be fixed to start the motor or should we buy a new replacement pump. We have a Hayward super pump 1hp.
