I have 2x 1/2 hp Mastercraft pumps from Canadian Tire that came with my house. They just keep working, I only need them in the spring with heavy rain. But they fire up whenever called upon. 1/2 hp vs 1/3 hp shouldn't make a huge difference, where are you discharging to? Mine just goes out onto the lawn, and higher hp would just make it shoot a bit further out the end of the discharge pipe.
