Getting to know if a vent stack can have bends in it is not a priority of most homeowners. In fact, homeowners typically do not take time to even understand how plumbing is tied into vents. Looking at your roof you will see various vents coming out of the roof. These vents have a variety of purposes. Vents serve your plumbing as well as appliances such as your appliance dryer. Can a vent stack have bends in it? Vent stacks can only have 45-degree angled piping to route horizontal pipe and connect to vertical pipe.
Let’s take a look below at what all of this means.
Why Is Venting Important
Venting pipes are vital to your health and safety in a home. Plumbing vent pipes are especially necessary in order to remove all sewer gases from your sewer plumbing. Plumbing air vents are connected to your plumbing. In fact, these vents push air pressure into your plumbing as you flush your toilet. The air pushes your waste and water through the sewer pipe and towards to city sewer pipe connection.
Your drain-waste-vent pipe is meant to carry waste and water through your home’s plumbing system while keeping fumes and gurgling out. So, if you plan to remodel your home’s plumbing system, make sure you consult a professional licensed master plumber. They can inform you as to which plumbing choices make the most sense for the setup of your home.
The drain-waste-vent pipe is run vertically and connected to your horizontal pipes. The pipes are run horizontally so that water can flow directly to the city sewer system so don’t ever use a tight 90-degree elbow. This is often called a vent elbow and used if the joint of your pipes is below the water level of the sink. Your plumbing vent pipes must be installed straight on the vertical as this keeps fresh air in and all drains in the house working properly.
What Are The Venting Types
There are a variety of vents that run throughout your home. Each homeowner should begin to understand which vents does what. Whether you are buying a home or getting to know more about your current home, vents should be kept clear of debris and in good working condition. Let’s take a look at the vent types in your home.
- True Vent – a vertical pipe that is attached to a drain line. It travels through the roof with no running water. Fixtures on the top floor of a home are closer to the upper stack and this serves as a great vent option.
- Auxillary Vent – attached to the drain line nearest to the fixtures and goes up and over your main vent. This can attach directly behind the fixture or to your horizontal drain line.
- Common Vent – found on back to back sinks and tied together by a sanitary cross. These fixtures are found on opposite walls.
- Loop Vent – used when you have a freestanding sink.
- Air Admittance Valve (AAV) – when waste is drained, air is let into the vent pipe. After air is allowed into the vent pipe, gravity closes the vent, keeping the sewer gases from releasing back into the room. Code restrictions determine how many fixtures can be vented this way. These are now allowed per most local building codes. An AAV can now replace vent lines.
Can A Plumbing Vent Pipe Have Bends
Understanding how your plumbing vent pipes work is important. If you don’t know the proper way that these pipes should be installed, then you should stay away from this project. Plumbing vent pipes are meant to be straight and vertical. Under no circumstances should a plumbing vent pipe be installed with a 90 degree angle PVC joint.
Any angles should be limited to one 45-degree angle from horizontal pipe if the pipe needs assistance running through the attic and up through the roof. Plumbing vent pipes are used to allow fresh air into your plumbing system so that all drains work in the house.
