Your home’s plumbing system is composed of interconnected pipes that work together to keep wastewater moving smoothly. A stack pipe plays a critical role in this operation.
It collects all waste and sediments from sinks, showers, toilets, bathtubs and other fixtures in your plumbing drainage system. Furthermore, it regulates pressure within that same plumbing drainage system.
Vent Stack
A plumbing stack pipe is a vertically oriented pipe typically found on the roof of a home. Although it doesn’t look much like a chimney, it serves as the vent for pipes coming from sinks, showers, and toilets.
The stack pipe is an essential element of your home’s drainage system, providing air displacement. It prevents toxic gases from building up inside waste pipes and ensures water flows efficiently through it.
In some homes, you may not be able to see your vent stack because it may be situated at an angle or behind the wall. If this is the case for you, take extra effort to locate and fix the issue.
Typically, the top of a vent stack is made from copper or galvanized steel. These materials are strong and resistant to corrosion, making them an ideal choice for your home’s vent stack.
Vent stacks come in many varieties, but all serve the same purpose of controlling air pressure within your piping system and facilitating proper wastewater and fresh water flow in your home.
Most often, vent stacks are connected to a drain line via vertical pipe that is fastened directly onto the drain. This type of vent is known as a true vent.
Another popular vent type is a revent, which attaches to the drain line near a plumbing fixture and runs up and over to the main vent. While more convenient to install than true vents, they’re not quite as durable.
Finally, relief vents are another viable option for tall buildings (11 stories or higher). This type of vent connects upward from a soil stack or vertical waste stack to an elevated location to prevent drain venting issues caused by pressure changes within the stack pipe.
The main drain line from each fixture in your home travels through stack pipes and into a waste pipe, acting as the primary vent for wastewater from all of your drain lines. In some cases, this vent leads to either a sewage treatment facility or septic system. If the main drain line is made out of clay or other porous material that absorbs tree roots and causes backups of wastewater into your residence, contact a professional augering service to auger it out.
Clean-Out Stack
A plumbing stack pipe, also referred to as a clean-out stack, is one of the primary drain pipes in your home’s plumbing system. This pipe carries wastewater and sediment from various areas such as sinks, toilets, bathtubs, and showers throughout your residence.
A stack pipe is essential for the plumbing system’s proper function, keeping water moving through your home’s pipes and keeping sewer pipes unclogged. If a stack pipe becomes blocked, it could cause water backup, sewage backup, and other issues in your home.
If your stack is clogged, a plumber can snake or use a hydrojet tool to break up the blockage and clear out the pipe. After clearing away the obstruction, they’ll install a new cap or roto-root your primary drain line for maximum effectiveness.
Cleaning out a stack is no small feat for plumbers, yet it is necessary. The issue can arise due to many reasons such as tree leaves, dust, small dead animals and plastic materials that get blown around in strong winds.
Insects and rodents can enter your house through damaged stacks, so it is important to contact a pest control company right away. These pests and rodents can pose serious health risks for you and your family if left unchecked.
Tiny rust spots on your stack pipe can weaken the metal and lead to leaks or worse. These are called barnacles and they may be difficult to detect, but if you see them appearing on your pipe, take action right away!
Sewer odors or bad smells may indicate your plumbing stack is clogged. These unpleasant odors can negatively impact the quality of life for you and your family members.

Cleanouts are required on all sanitary drainage lines that turn more than 45 degrees, as well as horizontal waste and soil piping.
Secondary Drain Stack
A plumbing stack pipe is the main drain line in your home’s drainage system, transporting waste away to the sewer. It’s part of a wider network of pipes connecting water fixtures like toilets, kitchen sinks (secondary drain lines), and showers to the house sewer.
This complex system utilizes vent pipes to ensure your drains run smoothly without any unpleasant noises, while also blocking odors from entering your home.
DWV systems come with various vents and traps. Some are standard P-shaped pipes that contain water, blocking odors and gases from entering your house. Others feature smaller holes that permit air passage through them.
The main DWV pipe is typically 3 or 4 inches in diameter and runs straight up through your home’s roof. Branch drainpipes of smaller diameters collect wastewater from different fixtures before being routed to this main stack.
These smaller drainpipes are connected to various vents and traps, which ensure your pipes and sewage drain properly. Furthermore, they prevent walls and floors from getting wet – leading to mold formation or mildew growth.
If one of your drains is obstructed, fixtures will likely drain slowly – another indication of an issue with your plumbing stack pipe. You may need to hire a plumber to inspect your pipes and determine what’s causing the problem.
In addition to clogged stack pipes, other issues can develop around your plumbing stack, such as leaks, breaks and rust spots. If you notice any of these issues, get them rectified immediately.
Rotten drywall or wet spots on your walls: These are signs that your plumbing stack has a leak and is causing moisture damage to the walls of your house. If not addressed promptly, it can lead to mold growth, mildew growth, an unpleasant odor and the deterioration of your home’s structure.
Sewer odors and sewage stench can make it difficult to sleep at night, relax or think clearly. These unpleasant aromas may even give you headaches or nausea – another major reason why replacing your plumbing stack is recommended.
Primary Drain Stack
A primary drain stack is a vertical pipe that collects waste from all fixtures in your home, such as sinks, toilets, tubs and showers.
Typically, this pipe measures 4 inches in diameter and runs under your basement or foundation slab. It will remain invisible from outside your house unless you need to repair or add a new pipe.
Plumbing stacks are essential, directing water from fixtures to the sewer system rather than flooding your property. Without them, homeowners would need to rely on horizontal pipes which don’t transport wastewater as quickly as vertical ones do.
The main drain stack, also referred to as a soil stack or soil lateral, serves two important roles in your home: it removes sewage from the system and releases sewer gas through the roof. Furthermore, it helps regulate air pressure within your entire drainage system by eliminating negative air pressure that could lead to plumbing issues.
Plumbing stacks fall into three main categories: vent stacks, drain stacks, and soil stacks. Each of these components plays an essential role in your drainage system and must be kept up-to-date.
With any plumbing system, it’s essential to understand what each category of stack pipe does. Doing this will enable you to make informed decisions regarding maintenance, repairs and replacements.
Before we dive in, it’s essential to comprehend what a drain pipe is. This line transports all wastewater from your sinks and toilets up through the floor until the bottom of the trap and eventually connects with the sewer system.
It’s essential to comprehend what a vent pipe is, which connects to your drain line’s venting component. This large pipe transports odors away from your home and also releases gas which may be hazardous or unpleasant.
Maintaining your plumbing stack is the best way to keep it in optimal condition. In addition to cleaning it out, check all connections between secondary and primary drain lines for any obstructions – this will save time and money in the long run.
