Plumbing systems are incredibly complex, hosting many different components that the average homeowner might need help to understand. One aspect of a plumbing system that commonly causes confusion is the air gap. Air gaps are used most often in dishwashers, sinks, and bathtubs, and despite not being well-known, they actually fulfill a vital function. So, let’s learn more about air gaps, how they work, and how they protect your water supply each and every day.
What Is an Air Gap?
Funnily enough, an air gap is exactly what it says – a gap made of air placed in between parts of your system. In more technical terms, the air gap is a small space that separates the end of a pipe from a fixture such as a dishwasher or sink. This gap is usually about an inch wide but can be larger depending on the fixture’s needs, the local code requirements, and other criteria. You may not know it, but this small gap plays a big role in how your system works. Therefore, it’s incredibly important to have one and ensure it’s working properly.
The Importance of an Air Gap
But why is this little gap in your system so important? The answer isn’t apparent when all is working well; instead, an air gap comes into play when a backflow occurs. In short, backflow is when water flows backward in your pipes, which isn’t supposed to happen. This can cause dirty, unsanitary water to be pushed back into your clean water if you don’t have an air gap. There are plenty of health hazards that come from drinking unsafe water, including a whole host of illnesses that you definitely want to avoid. So, with an air gap, the unclean water won’t be able to reach your drinking water, keeping you and your family safe and healthy.
Air Gap FAQs
Do I need an air gap in my plumbing system?
If you have a dishwasher, sink, washbasin, water purification system, or other fixture that requires one, yes, you absolutely do need an air gap. On top of being important safety measures, air gaps are often required by local codes and regulations. The plumbing and air gaps in businesses such as restaurants come under heavy scrutiny, so they must follow these regulations rigorously.
What is an air break? Is it the same thing as an air gap?
An air break is not the same thing as an air gap. A gap is an open space, while a break is an indirect connection where the drain line terminates below a flood level. An air break can be useful for some things, but it doesn’t fully prevent backflow from contaminating your water supply, which makes air breaks inferior to air gaps overall.
What do I do if there’s a problem with my system’s air gap?
When it comes to air gaps, you don’t want to take any risks, or else you’ll put yourself and your family in harm’s way. Air gaps can run into problems such as clogging or knockout plug issues, and while some of them can be fixed by a handy DIYer, it’s always recommended to call a plumber to address the concern. This way, you won’t have to worry about health and sanitation issues, as the job will be done right the first time.
