A kitchen sink drains into a pipe that runs underneath the kitchen sink. This pipe is connected to a larger pipe, called a sewer line, which carries waste water away from the house.
This is a question that we get asked a lot! The answer may seem obvious, but it’s actually not as simple as you might think.
Kitchen sinks drain into what is called a “sump.”
A sump is simply a hole in the ground that collects water. This water is then pumped out of the sump and into the sewer system.
However, there are some homes that do not have a sump.
In these cases, the kitchen sink drains into a pipe that goes directly to the sewer system.

Does Kitchen Sink Drain into Sewer?
The kitchen sink drain is connected to the sewer line. The sewer line carries waste water from the house to the municipal sewer system.
Does Kitchen Sink Drain to Septic Tank?
If you have a septic tank, your kitchen sink will drain into it. The septic tank is usually located underground, and it is where sewage and wastewater from your home are stored. The septic tank is typically made of concrete, fiberglass, or plastic, and it has a heavy lid that needs to be removed in order to access the inside.
Where Does Kitchen Drain Pipe Go?
If you’re wondering where your kitchen drain pipe goes, the answer may surprise you. The kitchen drain pipe is actually connected to the main sewer line for your home. That means that when you run water down your kitchen sink, it eventually makes its way to the sewer.
The main sewer line for your home is typically located in the basement or crawl space beneath your house. From there, it runs out to the municipal sewer system or septic tank. So, when you wash dishes or do other things that send water down the drain, just know that it’s all going to end up in the same place – the sewer!
Replacing Drain Pipes under Kitchen Sink
If you’ve ever had a clog in your kitchen sink, you know how frustrating it can be. Not being able to use your sink is a huge inconvenience, and trying to fix the problem yourself can be daunting. Calling a professional is always an option, but it can be expensive.
If you’re feeling handy and want to try to fix the problem yourself, here’s a guide to replacing drain pipes under your kitchen sink.
The first step is to identify what kind of pipe you have. If your home was built before 1980, it’s likely that you have galvanized steel pipes.
These pipes are prone to rust and corrosion, which can cause clogs. If your home was built after 1980, it’s likely that you have PVC pipes. These are less susceptible to rust and corrosion, but they can still develop clogs over time.
Once you’ve identified the type of pipe you have, it’s time to get started with the replacement process. If you have galvanized steel pipes, start by removing the U-shaped trap underneath your sink (this is where most clogs form). Next, use a hacksaw or similar tool to cut through the galvanized pipe just above where it enters the wall.
You’ll need two new pieces of pipe – one for each side of the cut – so measure carefully before cutting!

Kitchen Sink Drain Pipe Size
One of the most important aspects of any kitchen sink is the drain pipe size. The wrong size drain pipe can lead to a number of problems, including a slow draining sink, water leaks, and even flooding. That’s why it’s so important to know what size drain pipe you need for your kitchen sink before you purchase one.
The most common kitchen sink drain pipe sizes are 1-1/2 inches and 2 inches. These sizes are generally sufficient for most sinks, but it’s always best to check with the manufacturer or your local plumber to be sure. If you have a particularly large or deep sink, you may need a larger pipe size.
Conversely, if your sink is shallower or has a smaller basin, you may be able to get away with a smaller pipe size.
Once you know what size drain pipe you need, the next step is to choose the material. The most common options are PVC (polyvinyl chloride) and ABS (acrylonitrile butadiene styrene).
Both materials are durable and easy to work with, but PVC is typically less expensive. If cost is not a concern, then either material will work just fine.
Installing a new kitchen sink is not as difficult as it might seem at first glance.
However, getting the wrong sized drainpipe can cause serious problems down the road. Be sure to measure your sink carefully and consult with either the manufacturer or a professional plumber before making your final decision on which size drainpipe to use.
Conclusion
The kitchen sink is one of the most important fixtures in your home. It’s where you wash your hands, prep food, and clean up after meals. But have you ever wondered where all that water goes once it goes down the drain?
Your kitchen sink drains into what is called a trap. The trap is a U-shaped pipe that is connected to your home’s sewer system. The trap holds a small amount of water at all times, which creates a seal that prevents sewer gases from entering your home.
When you turn on the faucet, water flows into the sink and displaces the air in the trap, allowing more water to flow in and keeping sewer gas from escaping. Once the sink is full, the water level in the trap rises and blocks off the opening to the sewer line, preventing any more water (or sewage) from backing up into your home.
When you pull the plug in your sink, the standing water in the U-shape of the trap is siphoned out through a hole in one side ofthe U and down intothe sewer line.
