Great Main Vent Stack

Re-vent pipes otherwise known as auxiliary vents attach to the drain line near your fixture.

Main vent stack. These are excellent options when your sink is too far away from the main stack. Vent stacks in a household plumbing system work the same way. If you are more specific I can touch on how to do.

A re-vent or revent pipe in a plumbing drain-waste-vent or DWV system is an auxiliary vent that is attached to the drain pipe close to an individual plumbing fixture. They can attach right behind your fixture or horizontally to the drain line. This may prevent you from having bends in your plumbing vent since the lower horizontal connection will slope toward the stack.

How Drain-Waste-Vent Plumbing Works. The vent system serving each building drain shall have at least one vent pipe that extends to the outdoors. The plumbing throughout a home is connected to a main plumbing stack that runs from the lowest level of the home and often times vents through the roof.

A plumbing vent or stack as the pros call it runs from your plumbing through your attic to the top of your roof. A secondary stack perhaps 2 or 3 inches in diameter serves a branch of the system. Water and waste will again freely flow down into your sewer line or septic system.

The stack connects to the homes soil stack and branches off into the every room that uses plumbing pipes. The main stack is a vent pipe that runs through the center of your home and exits through the roof. If you had the vents below then you may get watersewage in them and your house would stink and possibly drains would not function as well.

As per the 2006 International Plumbing Code all branch vent pipes and the main vent pipe should also be connected and graded in such a way that allows them to drain to the drainage pipe via gravity. Cut the pipe as near to the fitting as possible. Branch drainpipes of smaller diameter typically 1-12 or 2 inches.
