Newbie question..... Does the change in outside temperatures affect plumbing pipe noises in the wall? When an upstairs toilet is flushed, I hear a knocking noise in the walls. It's not a drip, it's a knock. It seems, however, that I'm now hearing a knocking noise when I flush any toilet in our home (two story). I had a plumber out initially who advised that it wasn't a leak/drip but rather a pipe that probably wasn't fastened. I have an associate who's a plumber that said the same thing. We have no evidence of water damage, leaks etc. but it seems to be more prevalent now that we have colder temperatures. Can colder outside temps (teens) affect plumbing noises? Help.
