Your home has several types of exhaust systems in it, from the furnace and fireplace chimney to the dryer vent and kitchen fan. However, one crucial but often unnoticed exhaust or vent system is the plumbing vents and vent stack. Did you know that although your plumbing vents are low maintenance, they still need a little TLC in the wintertime, too? Interestingly enough, your plumbing vent stack is actually susceptible to freezing in the winter. It happens in frigid regions. If you didn’t already know this, it’s no big deal. Truthfully, the plumbing vent system is often overlooked. So, unless you are a professional, it can be hard to know all the ins and outs of your plumbing system. But that’s where your local Beavercreek Plumbing & Drain experts come into play. Our goal is to keep you informed, illuminate the significance of your plumbing vents and vent stack, and provide strategies to prevent them from freezing. 

Understanding the Role of Plumbing Vents and the Vent Stack:  

The primary function of the plumbing vents is to release sewer gases out through the roof by way of the vent stack, effectively preventing the presence of these gases within your living spaces. It’s crucial to note that most homes feature a single vent stack, linking all drain lines to the plumbing vent system within the house. However, some residences may have multiple vent stacks on their roof.  

Vent stacks are typically crafted from cast iron, galvanized steel, PVC, and CPVC. Plumbing vents connect to sinks, toilets, tubs, and other drains, maintain air pressure, prevent siphoning, control odors, and avert backflow, all of which contribute to a well-functioning plumbing system.  

Recognizing a Frozen Plumbing Vent Stack:  

Although plumbing vent systems usually demand minimal maintenance, they can pose issues during extremely cold weather, especially in Ohio. When a vent stack freezes and becomes obstructed, it cannot perform its job. This means those noxious sewer gases within your home will have nowhere to be released and accumulate in your home, leading to many potential plumbing problems.  

You can visually inspect a vent stack from the ground. If it has ice buildup, this indicates it’s frozen. But as with all things, safety is paramount. So, please don’t go climbing onto the roof to rectify this issue. Lastly, another telltale sign of a frozen vent stack is slow-running toilets or gurgling noises from your toilets. 

Prevention of Frozen Vent Stacks:  

  1. Pipe insulation is a key preventative measure. Wrapping the pipe leading to the vent stack from your attic can aid in the prevention of ice buildup.   
  1. Pouring warm water down infrequently used drains and running hot water from faucets helps maintain trap fullness, which prevents freezing. Keep this tip in mind, especially for floor drains.  
  1. Try to make sure that the vent stack is clear of debris, such as leaves and twigs. Loose debris paired with winter weather is a recipe for a disastrous and stubborn ice clog. But we want to reemphasize the importance of practicing safety. So, please don’t get on top of your roof unless you are a professional.  
  1.  An insulated cap for your vent stack is another excellent option to help the component heated.  
  1. Heat tape can further prevent freezing issues if you have access to a portion of the vent stack from your attic.   
  1. Opening the attic door to allow warm air into the attic can raise the temperature in case of an already frozen stack. Remember that, though effective, it may temporarily increase your heating costs.  

Conclusion:  

By diligently applying these tips, you can safeguard your plumbing vent stack from freezing this winter and ensure your plumbing system’s smooth operation. Moreover, regular maintenance and preventive measures during colder weather significantly reduce the risk of freezing.
