About the running every one or two minutes Adjust the float so it has a longer shut off period as this short cycling will destroy the pump faster then anything else
IF the pit doesnt drain completly this is also normal as a lot of installers try to keep the impeller off the bottom of these pits to keep foreign objects from blocking the impeller.
If the pit doesnt drain at all with eithe pump Id check for a stoppage in the discharge line.
Hopefully your installer didnt use one line for both pumps for drainage.
