Why Do I Need A Plumbing Vent
What is the purpose of a plumbing vent? A plumbing vent ensures the smooth running of the plumbing system. Keep reading to discover why plumbing vents are so important.
In a typical household, there is always a constant flow of water; however, a hidden component keeps this system flowing smoothly.
This underappreciated element in the plumbing system is none other than the plumbing vent. Realising the importance of this unassuming vent can be the difference between smooth operation and clogged pipes.
Beyond just the plumbing system, a plumbing vent also plays a significant role in the drainage system. If this isn’t enough to convince you why you need a plumbing vent, read on. We will go over the various benefits of this vent and its different types and identify vent-related problems.
Let’s jump right into it, shall we?
Most people think of plumbing systems as the inlet and outlet pipes that carry water around the house. Drain pipes remove waste and dirty water from the sewage system. Meanwhile, supply lines are what we use to draw water into the building for sinks, appliances, and other daily needs.
Alongside these essential piping arrangements, a plumbing vent pipe regulates airflow in the entire system. Although it may seem out of place, it has one of the most vital roles. It works by creating vacuums to control the direction of air in both drain and supply lines.
As a result, a plumbing vent system essentially uses air to pump water into the home while pushing waste material and dirty water out of it. Regardless of how clean and well-maintained other drain pipes are kept, they would not function without the plumbing vent pipe to move the water.
The plumbing vents are also crucial for preventing sewer gasses from entering your home from the sewer system. Without these vents in place, sewer gas would slowly build up and make its way into rooms.
Not only are these sewer gasses unpleasant, but they can also be quite dangerous if inhaled. Potential poisoning and other ailments are highly likely in individuals exposed to such sewer gases without proper protection.
Due to this feature, plumbing vents are typically located on the roofs of houses and buildings. HVAC systems are also kept far away from these plumbing vents to prevent them from entering the home through another vent. Ultimately, limiting the frequency of contact with humans is the end goal of plumbing vents.
Among plumbing vents, a few variations are specialised for specific installations and purposes. Below are some of the different types of vents and where you can find them.
One of the most commonly found plumbing vents, a true vent, is attached directly to the drain line. It is responsible for regulating the flow of gasses in the plumbing system. No water runs through these pipes, allowing them to vent the air onto the roof, leaving your bathroom with clean, fresh air.
Usually, common vents are used when two fixtures, like sinks, are in separate rooms and share a common wall. These vents are connected to a stack (known as vent stacks) with a sanitary cross to differentiate them from the other drain pipes in the plumbing system.
This vent acts as a pathway, attached directly to the drain line or used behind a plumbing attachment like sinks and tubs. Down the line, it connects other plumbing fixtures to the central vent to control the gas buildup.
An incredibly important type of plumbing vent, the AAV acts as a buffer to stop gasses from moving into a room while wastewater is drained. When opened, this wastewater pipe can release a sudden influx of harmful sewage gas, which gravity stops due to the AAV. Typically, these vents are used for multiple plumbing fixtures around the home, much like the true vent.
Identifying an issue with your plumbing vent pipe can help you determine the best course of action to get water flowing smoothly again. Although you can tackle problems with plumbing and drainage pipes, a plumbing vent demands extra attention.
One of the best steps to take before proceeding is figuring out the source of the blockage. One way to watch a blocked vent is a gurgling sound in the drainage pipes. Other tells include a backup of wastewater, little or no drainage in sinks or tubs, and an unpleasant odour from sewage gas.
If you feel the cause of your blockage is due to a blocked plumbing vent, it is highly recommended to call in professional help. When a blockage is allowed to remain in the pipes, a high chance of a sediment buildup will occur. This buildup can eventually damage the pipeline and cost a hefty sum to repair.
It is safe to say you are more aware of why plumbing vents are so important in any plumbing and drainage system.
Ensuring your vents are working correctly can be beneficial to have a system that runs as seamlessly as possible. After all, no one likes blocked drains and the hassle they entail to fix. Not to mention, plumbing vents keep unpleasant odours away from our living spaces, and we owe a lot to this system of pipes.
Without these plumbing air vents in place, no modern home is complete, allowing our daily necessities to be met. On that note, we will conclude our guide on why these vents are so important. Please contact us if you need any assistance with plumbing vents in Melbourne!
