Why would he be listening to pipes? Is he listening for leaks?

Yes.

I've seen them wandering about town in the dead of night with their
sticks. Presumably the only time it's quiet enough

Also, fewer people will be running taps, which as well as masking the
actual sound of the leak reduces the local pressure allowing some
leaks to close.
