Lately I have heard a little knocking from my pipes in the evening and
thought nothing of it. I have had or should I say there has been a
gallon can under I guess a vent/drain pipe since I have bought the
house (approx. 2 months). Today that can was overflowing.
Can anyone tell me what would cause this? we are planning on
finishing the basement and would like to not have this water problem.
Thank you very very much for you help.
