The problem is a malfunctioning check valve. It'll be somewhere in the line on the pump output side. If it's not a separate fitting it'll be in the line, probably in an elbow.
Need further info, let me know...

If there is air in the pump it cavitates and can make it run louder, otherwise it is the bearings in the motor.

The pump seal is leaking and needs replacing and requires removing four 3/8 bolts (9/16) wrench and removing the motor then the diffuser to get to the impeller and seal . A 7/16 wrench holds the rear motor shaft behind the springs and impeller spins off to reveal the seal which has two parts one on the impeller with a spring and one in the seal plate is white ceramic/ porcelan whatever they use. Part number is an SPX1600KA on super pumps and 1500KA wassome above grounds. When replacing do not touch the mating white and black surfaces with your fingers.
