Home Equity and Refinancing

What would cause your neighbor in the town home next door to hear pipes rattling in her basement every time you flush the toliet?

I believe that one cause would be air in the lines. A plumbing system must have a vent in order to drain properly, if the vent is of improper size or improperly installed the drain will gurgle much like a gallon of water turned upside down sucks air in through the water. In metal pipes this sound will echo and create a rattleing sound, moreso than plastic pipes.
