Dear experts:

I am a new home owner and know almost nothing about the house. Hopefully you can help me out with this annoying sound.

Recently I heard some dripping sound from the ceiling between ground and second floor. I never heard about the noise before until last week I raised the temperature setting of the heater due to cold weather. So far, I didn't see any water stain on the ceiling or wall. I noticed that the frequency of the dripping sound is higher when the heater is working and get lower when the heater stops.

I am so afraid that it is due to water pipe leak and the noise really drives me crazy. Does anyone have any clue about what it is and how to solve it? Your answer is highly appreciated.

Thank you!

A Nervous New Home Owner!
