1.Plumbing vent, also known as a vent stack, helps regulate the air pressure in your plumbing system. Just as drain pipes remove water and waste from your home, the plumbing vent pipe – also known as a plumbing air vent – removes gas and odors.Read More

It also allows fresh air into the plumbing system to help water flow smoothly through the drain pipes. However, no water runs through the plumbing vent pipe. It is a vertical pipe attached to a drain line and runs through the roof of your home. The vent stack is the pipe leading to the main roof vent. It channels the exhaust gases to the vent and helps maintain proper atmospheric pressure in the waste system.                                                                                                                                                                                                    2 Plumbing Vent  can be considered as having a glass of water in front of you with a straw to drink. If you place your finger at the top end of the straw; sealing it while lifting the straw out of the glass, you will see that the water  remains in the straw until you remove your finger. This is the same principle by which venting occurs in the circuitry of your plumbing.                                  In simple form , when air is allowed in your vent pipes ; then gravity allows waste in sewer line to run freely. In most cases, you will find that your waste, especially  in bathtubs , kitchen sinks and areas where grease is predominant.                                         Why knowing how Plumbing Vent is Important?                                                                      3.Your home’s plumbing system is designed to efficiently remove water and waste. Its drainage and vent functions are actually two systems that work together.                                                                                                                                                            4.Drainage pipes carry waste out of your home to either the city sewer or a septic tank. Plumbing Vent pipes supply fresh air to each plumbing fixture in the house, which helps the system move water through the drainage pipes each time a toilet is flushed or a sink is drained.                                                                                                                                                                                          5.Plumbing vent also prevent sewer gases from entering the home and allow wastewater gas and odor to escape. Plumbing vent pipes are located on roofs, away from windows or air conditioning units, so that the fumes can  as well disipate.            Problems With Plumbing Vent Pipes          6.When plumbing vent or vent stacks do not work properly, neither will your home’s plumbing drainage system. If you hear gurgling sounds coming from your drains, see standing water in your sink or bathtub, or notice a slow drain in the bathroom or kitchen, a blocked vent may be the issue.                                                  Below is a video on how to vent plumbing
