No idea on any age correlation but the sound was identical and took months to isolate the first time. Once I’d heard it I knew exactly what it was by the 2nd time.

The LL and I just had to work with other tenants. Luckily they were all accommodating, let me have one person in their unit running hot water while someone else waited downstairs in mine listening. We found it within the firs couple units both times.

Appreciate the advice! I’ll have to see if I can get in the other units and try something similar. Fingers crossed it’s something simpler

That’s exactly what mine sounded like. Suppose it’s entirely possible with any temp mine is just always more prevalent with warm water. But suppose if the pipe passes through an area that’s not well insulated in cold areas even “cool” water could cause at least some expansion.
