In the U.S., every plumbing fixture must also be coupled to the system's vent piping. [1] Without a vent, negative pressure from water leaving the system can slow flow (resulting in clogs) or cause a siphon to empty a trap. The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.
As one of the most widely used rehabilitation methods, CIPP has applications in sewer, water, gas, chemical and district heating pipelines ranging in diameter from 0.1 to 2.8 meters (2–110 inches). The process of CIPP involves inserting and running a felt lining into a preexisting pipe that is the subject of repair.
Orangeburg was a low cost alternative to metal for sewer lines in particular. Lack of strength causes pipes made of Orangeburg to fail more frequently than pipes made with other materials. The useful life for an Orangeburg pipe is about 50 years under ideal conditions, but has been known to fail in as little as 10 years.
The manholes are used for access to the sewer pipes for inspection and maintenance, and as a means to vent sewer gases. They also facilitate vertical and horizontal angles in otherwise straight pipelines. [4] Pipes conveying sewage from an individual building to a common gravity sewer line are called laterals.
A common type of this style fitting is a "hex bushing" with a hex head for installation with a pipe wrench. A double-tapped bushing is more compact than a reducer but not as flexible. While a double-tapped bushing has a more minor female thread concentric to a larger male thread (and thus couples a smaller male end to a larger female), a ...

A sanitary manhole (sewer manhole, [1] sanitary sewer manhole [2] or sewer maintenance hole [3]) is a manhole that is used as an access point for maintenance and inspection of an underground sanitary sewer system. Sanitary manholes are sometimes used as vents to prevent the buildup of pressurized sewage gas. [4]
