Second discharge line?

I am planning on putting a second submersible sump pump into my sump hole as a backup. It will be on it's own 15 amp circuit. Is it alright to add to the pvc pipe that I'm using with the original pump, or should I make up a second line? In case of power loss I plan on running two 12 gauge extension cords from my 5000 watt portable generator. Make sense?

The only thing I could think of is putting check valves in the lines, as one pump will cut on and run the water backwards through the other pump using a common discharge.
