the pipes are plumbing venting system. For water to drain freely out of a
house waste system, there must be adequate venting. The venting performs
three functions. It allows air in front of the water rushing through the
waste pipe to be
pushed out of the way, and it also allows air to be reintroduced to the
waste piping after the water has gone by. Lastly, it allows sewer gases
to escape outside through a vent stack. |
