When I started pumping a new Pumpico floor pump, the shaft slid down doing nothing for about 12 pumps and then kicked in for 2 hard pumps before it did nothing again for another 10 pumps. It's a schrader valve. My tires needed only a little air. Do I have a defective pump?
When I pump the shaft when it's not connected I feel no air coming out of the tube. Is that normal?
