Plumbing vents are important to any plumbing system. The main task of these pipes is to create equal pressure in the pipes by allowing air to flow into the drainage system, which will let the waste to flow passively out to the septic system or sewage. When this is blocked or wrongly installed, the vents can cause gurgling noises, sewer odours and poor drainage.
If you are uncertain about the quality of the vents in your home especially if you see some signs of problems, make sure that you get it to check. But where are plumbing vents located, you may ask. Most plumbing vents stacks are placed on the roof but there are other places where it can be at the ground level or on the side of a building.
The main drain line
The vent pipes mostly run straight up and down from the main line of your house. This is commonly located in the basement or crawl space underneath the house. You can easily know that it is the main drain line because you can easily hear the pipes and the flow of the water especially when someone flush the toilet and you are in the basement near the drain line.
Your attic and roof
Once you know where the general location of your vent pipe, you can now check them in your attic or roof. The vent pipe in the attic is similar to a toilet drain pipe which is a diameter pipe. Some plumbing vent pipes are capped in the attic, or they could continue travelling upwards and will finish above the roof.
