Yes, at first I couldn't get anything through it. Then just a trickle. Finally, I got it to flow okay, but with a ton of back pressure. I saw the same behavior as last fall, and within a few days of flushing it the heater wasn't heating any more.
New radiator makes a huge difference from what I've seen so far. Still in the process of flushing before I fill it with.... well you know.
