It sounds like you're having two different problems, depending on the pump being used. Is that right? With the floor pump it sounds like the pump is working, but the air just isn't getting into the tire, like it's leaking out at the pump's chuck. With the Topeak it sounds like the chuck's seal is OK, but you're finding too much resistance, like the presta valve is sticking or something. Is that accurate? Just trying to get a better handle on the issue(s).
