What Are Plumbing Vents and How Do They Work?


Plumbing vents are essential because they lead from your plumbing appliances in your home to an outdoor area. Rather than water, plumbing vents carry sewer gases safely and effectively outside of your home since they are dangerous to breathe. Plumbing vents also bring oxygen in through the vents so that they can break down waste more quickly.

According to our expert Tampa plumbers, it is important to have your plumbing work with gravity so that there is neutral air pressure. If you have neutral air pressure, you won’t have to worry about waste water not moving out of the pipe. If you have poor air pressure, the sewer gas could circulate back into your home. With good neutral air pressure, your pipe will form a vacuum and pull out gas and push waste through efficiently.

In compliance with building codes, you are required to have a plumbing vent and a trap for each appliance in your home. Because of the necessity of proper ventilation and the fact that your family’s health could be at risk with poor ventilation, it may be in your best interest to have a professional Tampa plumber put in your plumbing vents. When plumbing ventilation is done incorrectly, the fixture can drain slowly, methane may leak into your home, water can siphon out and cause damage, and the drain could make a gurgling, bubble noise.

Most of the time, you will be required to have a vent stack with your plumbing vent. This will lead to the main roof vent of the vent system, within five feet of the appliance. Vents can get clogged due to pests or weather, so it is important to keep yours maintained so it does not back up and potentially ruin the interior of your home, as well as put your health at risk.
