In response to Re: Question on venting - what it should read - sorry

: : : What is the difference in a stack stack as opposed to a vent stack?

:
: A Stack Vent (sometimes called a waste Vent or Soil vent) is the extension of a soil or waste stack above the highest horizontal drain connected to the stack

: A VENT STACK is a vertical pipe instaled primarily for the purpose of providing circulation of air to and from any part of the drainage system

: Either one should be increased to at least 4" to prevent hoarfrost in certain areas and ideally you would want a Fresh Air inlet FAI installed 6" above grade and should also be half the diameter of the building house drain but in no case less the 3".

: Hey no one said its easy :-(
