Yep! Thats one of the videos I watched. It does sound like that for the most part... but it sounds like its harder and longer if that makes sense at all.
Also, Do you know anything about how/when that should happen? As in... Does the expanding occur right after the sink is used? Or can it happen at any time?
The knocking in my bathroom has stopped because it's not too cold outside right now, but when it's cold outside and we have the heat on inside, I hear the knocking quite often. It's strange because it will knock when the toilet is used, as well as when the shower is used.
The knocking in the bedroom seems to happen any time, but again, normally it is cold outside, or even raining, and warmer inside. I'm thinking it's a larger pipe or vent of some sort.
