 Intermittent Water Drop Sound
Author: jignesh5 (VA)

I hear intermittent ( or mostly first time, Once, morning or may be after a long time of no use of the bathroom) in the room below my bathroom.

It comes only when flush has been run or faucet is running. However, I am unable to reproduce the sound after few seconds even after I flush it repeatedly or keep running the faucet.

What could be wrong and how to at least narrow down the issue without opening up drywall?

running hot water can make pipes expand and actually move a tiny bit. his can cause a noise that might be interpreted as a drip-drip-drip.
BUT you say it happens when you flush the toilet ????
