depends on what kind of pump you have and whether it is for a home or business....there are dc pumps but they still only pump one way but if yoou reverse it, it might run but not pump...most home pumps are 120 volts and run only one way..if it is not pumping either the impellor is bad or something stopped up the drain line ...if it is for a business it could be three phase and could be reversed by changing any two hot leads..you or the power company would have had to do this....first thing to do is remove drain line and check it and make sure it is not stopped up...set pump in sump and turn it on for a couple of seconds just to see if it will pump....if it wount pump replace it ..if it does most likely the drain line is stopped up....

Your friend big bull doesn't know "bull." If the motor is running on a three phase A/C, you can change the direction by swamping two the phases of the three phases. The easiest way is at the motor contactor. If you have a motor controller that has a power converter (changes A/C to D/C or visa versa), then yes you can change the rotation on the motor; hence, the motor will be a D/C motor.
However, most fluid pumps only pump one direction but there are fluid pumps that will pump both directions, for instance, hydraulic pumps.
If it is a three phase pump system, someone had to have change the phases somewhere. If it was the power co., everything (not just yours) from that point on would be turning backwards.
Other than that, need more detail if you are positive it is turning the wrong direction.

If it is indeed, running backwards, which I seriously doubt, then somehow the polarity of the fields assemblies inside the motor would have had to be changed. This is pretty much physically impossible, without dissassembling the motor. You should probably just buy a new sump pump and replace it.

IMPOSSIBLE!!! A/C current only runs a motor ONE direction. So even if you flip the plug over in the outlet, it would still run the same direction. This cannot physically happen with A/C current. No way! Only D/C allows for a change in direction with a change in the currents path.
There may be a clog, or the impeller may be chewed up and not pumping, just churning up the sump pit.

its a sump pump

sounds like the impeller is clogged causing the water to push out the sides of the pump ..check for clogg in bottom of pump and in the line

Unless you've switched the wires around without telling us or the pump is plugged and spewing out the sides it's physically impossible to "run backwards" without physically changing the wires. If you bought it this way, take it back.

How do you know it is running backwards? Motors don't spontaneously switch rotation. Is it not pumping? You may have an impeller problem.

The polarity may be reversed. Switch the lead and neutral wire around or there may even be a switch that reverses the polarity.There are several pumps that pull or push water depending on the application.

sounds like a possible short.
