Ever catch yourself wondering “what’s that for?” Your home’s plumbing system is made up of an intricate network of pipes, vents, and drains. There may be some parts of your plumbing system that you are familiar with, then there are those parts you have not clue what purpose they serve. Today we are going to shed some light on the mystery plumbing parts that have been eluding you.


You may have noticed that funny looking knob next to your faucet on your kitchen sink, this is called a vacuum breaker. A vacuum breaker is designed to prevent backflow issues. They can also be found by toilets and hot water heaters. In the mystery case of the knob next to your faucet on your kitchen sink, it is hooked up to your dishwasher. The Vacuum breaker, or air gap as it is sometimes referred to is designed to help relieve pressure to help the waste water drain properly. Without a vacuum breaker, waste water could travel back into the dishwasher.


A plumbing cleanout is a necessary part of your plumbing. You may have noticed a funny looking cap with a square in the middle, that is your cleanout. You may have more than one depending on the size of your home. Cleanouts are often located right on the main sewer line. They are designed to provide for easy access, for cleaning, snaking, or video pipe inspection.


The water supply is one of the most important parts of your plumbing to know. In the event of a plumbing emergency, knowing where your water supply is and how to turn it off could make a huge difference. First there is the main water supply. If you have a major plumbing like, like a burst pipe, you will want to turn off the main water supply. Most main water supplies will be located around the foundation of a home or in the ground out front of the home. In addition, each water using appliance and plumbing fixture will have its own water supply, you may have noticed that knob on the back of your toilet, that is the water supply. If your toilet overflows, or if you are replacing your toilet, this is where you will turn off the water supply.


Another common mystery plumbing part and an important part of your plumbing is the overflow drain. Each bathroom sink and bathtub will have overflow. This prevent the sink or bathtub from overflowing, which could lead to flooding. Overflows are usually placed at the front of the sink or under the faucet.
