Believe it or not, plumbing isn’t always what it seems from the outside. One might think things are as simple as connecting pipes together and turning on the sink or filling up the tub and seeing it drain through. While all the proper seals and connections might make this situation very possible, there are many other factors that play into the effectiveness of your plumbing you may now know about. The one we will be talking about today is plumbing venting.
Your drainage system is much more dynamic than a good seal between pipes (as we are all aware that poor seals can cause the pipes to come apart or for water to leak at the “joints”). It does its job thanks to a variety of factors, some including the pitch of the pipes and just how the water flows down through the pipes. All on its own, water flowing through your pipes requires the help of another system to be able to flow efficiently. What could possibly be needed to help water simply flow, you might ask? Well continue on, fellow plumber, interested homeowner, or whoever else you might be that wants to know what could be so difficult about water traveling through a perfectly good pipe.
There are two main components used for drainage pipes, the drain, and a piece called the vent. They look rather similar, but serve two different purposes. The drain’s purpose is rather self-explanatory, but the purpose of the vent is solely intended for the helping of air movement while the water is traveling. For example, when you flush a toilet, the water drains down through the pipes. As the water pushes down through the pipes, it is also forcing air down with it.
There is always air moving within a plumbing system at all times and in the vent piping. Essentially, what a vent is designed to do is relieve the pressure from the pipes and draw in air that will help balance out the plumbing system. Let’s look at the example once more, but as it is related to a venting system. After you flush the toilet, the water pushes down, and pulls air into the pipes behind it through the vent, dragging it behind it. Any air that is being pushed out by the water leaves the home or business through another vent to escape as outside air, creating a circulation that keeps water flowing freely through the entire plumbing system smoothly (given there are no other problems!).
If your plumbing does not have a proper venting system, you would not see the same results. Let’s look again at flushing the toilet in this scenario. The increase in air pressure when you flush will cause the exiting water to draw the water from the trap (a small curved piece of piping that water sits idle inside of to seal off the gases from your sewer from entering into the room) to follow behind it, instead of drawing in air, and empty the trap. Since the empty space behind the water will be filled with one of the other, this situation leaves the sewer pipe clear for the gases to enter your home or business!
As you can see, a venting system is important to have as part of your plumbing system. Simply installing the piping your toilet and other fixtures need to eliminate water from your home won’t do the trick by themselves. You can be too scarce with your venting, through, so be sure to plan out how many vents your system will use to be able to draw in the air it needs everywhere in the house that it is relevant. Another important tip is to consider that when your drains are acting up, that it is possible there might be a clog in one of the vents that is preventing the air from being drawn into the plumbing!
