This pump was put in last May by my pool company under warranty. The pump runs year round with a Pentair Controller on average of 18 hours a day during season and around 8 hrs a day off season. The check valve is working fine and there is always water in the sump when the pump is off.
Make sure all wiring is good loose wires can comprimise the life of a motor

You might want to pull the drive wheels and see if their might be a small pebel stuck in the drive gears on the wheel.
SOURCE: my pentair whisperflo is making a load squealing
When you have noise in the pump it is usually a rumbel or rattel. If you have a squealing it is probally in your motor and is more than likly a bad bearing. If you have any water leaking at your seal this is probally the problem and it will just get worse. Sorry to say you are very close to a new motor.

If you just bought this then there will be a diagram on the motor nameplate and/or under the terminal cover where you connect the wires. Generally speaking, there are two wires inside the motor that change positions depending on 115 or 230 v connection. If one of the wires is on a post common to one of the line leads, that usually means you have the motor set for 115V. Is that the voltage you are supplying to the motor? If there is no diagram you can make out on the motor, post what brand motor and the motor model number for a diagram.

It could be the pump is bound up but it is more likely the motor is failing. It may be a small part such as the capacitor or the starting switch, but could also be more severe such as the winding itself. You will also want to examine the shaft where it passes thru the pump and motor and look for signs of rust from a pump seal leak.
If you are not familiar with testing these parts your best bet would be a local electric motor repair shop to see if the motor can be repaired or if it would need to be replaced. They should also be able to ensure there is no pump damage.
