Why Backflow Prevention is so Important

How’s that backflow prevention device working for you? Okay, the look on your face says it all, and your response is “What’s a backflow prevention device? What does it do? Do I have one?” Don’t feel badly. Based on our experience at Kotz Heating, Cooling & Plumbing, your response isn’t at all unusual.

At its simplest, a backflow preventer is designed to prevent drinking water from being contaminated by non-potable water, or water not suitable for human consumption. In most cases, it is a backflow valve which allows water to flow in only one direction. While they are more common in commercial applications, they are used in homes as well. They may be required by code, or at the very least recommended, because of certain local conditions.

The risk usually comes when there is a sudden drop in water pressure in your home, business, or in a public water system. Without a backflow prevention device, contaminated water can be literally sucked into the system. When you consider locations like restaurants, food processing plants, and medical facilities you understand why backflow protection is so vital in commercial plumbing systems.

If you have a backflow preventer in your home or business, you need to know it requires annual testing and you should call Kotz to make an appointment. Our licensed plumbers will make sure it is working properly. If you’re not sure you have one or not sure if you need one, we can assess your situation so you can make an informed decision about what’s best for you.

Backflow prevention is just one facet of ensuring clean water. The Flint water crisis has put everyone on alert about the safety of our drinking water. Kotz will test your water at no charge. All you have to do is bring a sample to our plumbing showroom or give it to our technician during the next visit to your home or business.
