Recent 2nd story addition. 3 bedrooms and a bathroom. Heated off existing boiler, one new zone with PEX running to Slant fin radiators.
Heats great, but there are several spots where the PEX in the floor/ceiling makes quite a racket. It's a ticking or a tapping exactly like the sound that starts 24 seconds in on this youtube video, but mine is worse, and does it in several spots. Of course, the noisiest spot ishappens to be over my bedroom downstairs.

the addition was a mix of pro work, and DIY, with the lions share going to the pros. This work was done by a plumber, and I didn't see the lines in this area before the deck went on, although even if I had, I wouldn't have known much about it.
After doing some research, my guess is one or some of the following, but I know little about PEX:
Connectors too tight
Joists drilled too tight
Routed sloppy so it taps against surrounding framing
Am I on the right track here? The noise is annoying, but my real concern is weather it's something I need to be worred about, more than it just being annoying. I seem to be the only one really bothered by it.
The worst of the noise is on the longest run that goes perpendicular to the joists along the front of the house. Seems to be the worst on the ends near the areas where it likely makes 90 degree bends.
If it matters, the boiler is a Burnham v73 with the aquastat high temp set to 180.
Thanks for any help in advance.
