https://sndup.net/5rpc/Tapping+sound.wavThis sound started appearing a week ago late in the evening. At first I thought it was a neighbour, but today I realised that tapping sounds could be produced by a water heater. I found some recordings of water heater sounds due to sediment at the bottom, which is not the same. But failed to find any recording of a tapping sound. If anyone can confirm this sound could be from a water heater, I would be quite grateful.Thanks via /r/DIY https://ift.tt/3lbiawV
