Good day! Sorry to hear that you're having a problem with your Liberty 404 Short Profile Drain Pump. How is the pump plugged in currently? Is one plug plugged into the backside of the other and both plugged into the same outlet or are they both in different outlets? For automatic operation, these need to be plugged into one another and plugged into the same outlet. If both are plugged into different outlets, the pump will have power fed to it and would cause it to run continuously. If it is plugged in correctly and still running continuously, I would pull off the access cover where the cord comes out and check to make sure that the float is not hung up in any way. If the float is hung up in the upright position, this could cause the pump not to turn off. Please check to make sure this is not the case. If you're still encountering problems with your Liberty 404, we recommend that you contact Liberty Pumps at 1-800-543-2550 and ask for Dan to discuss the issue further. Let us know if you have any questions. Looking forward to seeing you here again at Have a stress-free day!
