#1 Q:   I am looking to switch a mr.slim from the EC-400 to this pump over noise issues with the EC-400. Can I use the same wire harness from the EC-400 and whats the dBA rating on this pump?
A:   No, the wiring is different on the 2 pumps. As for noise, Little Giant does not publish (nor give out) any noise ratings for their pumps. Per their tech support, the EC-1 line is the quietest.
