Insulating the pipes is a solid tip. Did mine last year and it made a noticeable difference—less noise overall, plus the hot water reaches the tap faster. Another thing worth checking: pipe hangers or brackets. Loose hangers can cause knocking sounds when pipes expand or contract. Tightening or adding a few extra brackets sorted out most of my remaining noises. Just something else to keep in mind if the pinging ever creeps back...
Insulating definitely helps, but I'm always cautious about tightening brackets too much—pipes need a bit of wiggle room to expand safely. Last winter, I overtightened a couple brackets and ended up with a small leak at one joint (lesson learned the hard way...). Curious if anyone else has found a good balance between securing pipes enough to stop noise but still allowing for safe expansion? Seems like a tricky balance to strike.
"pipes need a bit of wiggle room to expand safely."
Yeah, learned that one myself after tightening brackets too much—ended up with creaking noises instead of leaks. Anyone tried those plastic clips with rubber inserts? Wondering if they're worth the extra cost or just marketing hype...
I had a similar issue when I first moved into my place. Thought I'd be proactive and tightened all the pipe brackets to stop any potential leaks—big mistake. Ended up with pipes creaking and groaning every time the heating kicked in. Took me a while to figure out it was because they had no room to expand.

Actually, I swapped out a few of my metal brackets for those plastic clips with rubber inserts about six months ago. Installation was straightforward: remove old bracket, slip the new one around the pipe, and screw it back into place. Honestly, it did make a noticeable difference. The rubber insert seems to absorb some of the vibration and noise, and the pipes definitely move more smoothly now. They're pricier, sure, but if you're dealing with annoying noises, I'd say they're worth trying at least in the areas where the pipes run close to bedrooms or living spaces.

I've used those rubber-insert clips too, but honestly didn't notice much difference compared to just loosening the metal brackets slightly. Maybe it depends on how sensitive you are to noise or how your pipes run through the walls... but for the extra cost, I'm not totally convinced.
