I have tapping noise from the heat system in my apt building. I know
what causes it. The pipes are expanding from heat.

For many years I heard a fast series of clicks every 30-60 minutes or
so, but lately, I've been hearing a "slow tapping," which is one CLICK
and then five seconds of silence and then another CLICK. This lasts
1-2 minutes.

Do you know why this "slow tapping" would happen as opposed to the old
tapping?

Somebody loves you. Are these two taps?
