Sump pump wont stop running

I have a Ridgid SP-500 sump pump that is only 1.5 years old. It will drain the water out of the pit and it sounds fine but when it empties the water it keeps running and then makes a loud noise like its just sucking air since theres no water. This happened a few months ago and all I did was unplug it for a couple of hours then when I plugged it back in it was fine. But now that it happened again so Im assuming something is wrong. In doing a little research I see things saying that it could be a switch problem or maybe a bad check valve. Also I saw about drilling a hole in the pipe just below the check valve or drilling a hole just above the discharge on the pump. I dont know anything about that so that kind scares me. Does anyone have any ideas what the problem may be? I can replace a check valve or the entire pump but I dont know anything about replacing a bad switch.

It sounds like the float is stuck in the up position. Did you look inside?

Yes, I move the float and switch up and down and it still keeps running. Would a piggyback switch help?

If you move the float switch up and down and the pump just keeps running, it's certainly a bad switch. If it's a separate switch, you can just get a new one. They also sell stand-alone float switches, but you'd have to be able to disable the one on the pump.

Do you have a model #?
