Fixing An Old Roof Vent

When it comes to those buying their very first home, one of the least understood components of a home seems to be plumbing vents. Those pipes sticking up out of the roof that run through the attic and through the rest of the house, are called roof plumbing vents. The majority of plumbing fixtures require a plumbing vent. Vents are frequently connected together inside the attic, which allows for less penetrations in the roof.

So what is their purpose? Believe it or not, when water drains in an upward motion, it is actually faster than when being drained downward. When draining downward, it’s only gurgling out while air replaces it. However, if drained upward with a hole at the top, water drains out at a quicker pace like a vent in a gas can. Roof plumbing vents also prevent traps from being siphoned and they prevent back-pressure on traps. Every plumbing fixture has a trap which prevents sewer gas from coming into your home. When water drains through a plumbing fixture, it can be enough water to create a siphon effect, which has the potential to pull water right out of the plumbing trap. Another main purpose of a roof plumbing vent is to allow the free movement of air in the drainage pipes, which protects the water seal of the fixture traps from siphonage. The roof vent termination is instrumental and should be installed properly by certified and professional roofing contractors.

Now that you know a little bit about the purpose of a roof plumbing vent, what about it you already have one and something seems to be wrong with it. These reasons below are sure tell signs you need some repairs:

  1. Something Doesn’t Smell Right

If you know what a rotten egg smells like, this would be it. If your home begins to smell like a rotten egg, it’s your plumbing vent. It could be clogged and that stops sewer waste to escape via the roof vent.

  1. Toilet Critters

Yes, bugs. In your toilet, none the less! Whether its through cracked pipes underneath the ground, or entrance through the rood vent, insects, frogs, and other small animals can find their way to your toilet. Unless you welcome this kind of trespassing on private property, I suggest a call to a plumber to repair your roof vent or pipes to rid your home of this invasion immediately.

  1. Sounds Coming From The Walls 

When you hear gurgling noises as fixtures drain, it’s usually the result of a vacuum being created in your plumbing system. This vacuum forms when there isn’t proper venting of a fixture or some other part of your plumbing system. The venting configured into your plumbing system helps move air and water through the pipes. If any part of the drainage or venting system is blocked, gurgling results as negative pressure makes the water push through trapped air in the system.

Remember, having a roof vent for plumbing is crucial for proper vetting of waste. If you have one already, great! Keep it maintained through out the year. If you don’t have one, It might be something worth while looking into!
