And once again, DX is your Friend: Cable Connectivity Tester (highly recommended!).
Or this one (slightly cheaper): the exact one I have here.

I do have a cable tester and I'm pretty sure I used it in this case and everything checked out. Would that make things change though? I would think it would be bad from the start...

Did you prod at it to verify that it really is rock hard cement? Usually the custom is to fill the end of the conduit with "duct seal", which is a grey firm putty substance, easily removed if needed. This keeps critters and drafts out of the tubing.

How firm? I prodded it pretty darn hard with my finger and felt no give. It felt cold and hard like cement, but I'll try poking it with something sharp the next time I'm there.
