In our last blog post, we covered a few tips and techniques that you can use to keep your kitchen sink from getting clogged. However, if you’re not in the habit of throwing food scraps into the trash, it may feel like a big adjustment to start doing it. You might be wondering if it’s really worth the effort.

If you’re used to calling a plumber every so often to unclog a kitchen drain that has gotten plugged, you might not realize that it is entirely possible for a sink to go for many years without ever getting slow or clogged. But other than the potential of avoiding so many applications of Drano, why should you be purposeful about keeping debris and food from going down the drain?

How Your Kitchen Sink Works

The design of your pipes makes it it easy to understand why you should be careful about letting food go down the drain.

If you open your cabinet and take a look at the pipes under your sink, you’ll probably see a U-shaped pipe, called the “trap,” where everything that flows down the drain must then reverse course and go back up (against the flow of gravity) on its way out of your home. The idea is that larger, heavier food particles will get caught here and that only the water will flow through.

However, if food is allowed to go down the drain on a daily basis, the food particles themselves get pushed on further into the plumbing. If food gets caught in the trap, it is in a place that’s easy to reach and easy to access when it needs to be cleaned out. However, the fuller this trap gets, the greater the danger that more and more food will flow through the trap and create a clog lower down. If a clog happens lower down in the pipe, it is hard to access and clean out, and it may not even be possible to fix with a snake.

Main line clog

In addition, it is very possible that your kitchen sink’s drainage connects to a point that is near your home’s main line. Think of the plumbing network in your house like a tree with one trunk and many branches. The main line is the trunk, and it is where all the sewage, water, and other drainage flows away. Kitchens with a sink that connects near the main line are at a high risk of clogging the main line. If this happens, it can even cause your toilets, shower, and other sinks to back up. You definitely don’t want this to happen, and if it does, it’ll be much more inconvenient than taking the simple, necessary measures to keep food from going down your drain in the first place.
