Back flows are mechanisms that are used to keep drinking water safe from contaminants. They are important pieces to the water supply, and homeowners should hire a contractor for back flow testing every couple of months to ensure that their drinking water stays safe. This video will explain how to be certified as a back flow tester.
The first thing you need to do is gain experience working with back flows. The certification process requires a few years of experience to get certified as a tester. On top of this, you need to register with a specialized training program to understand the regulations that govern back flows.
Of course, you need to know how back flows work. There are multiple types of back flows that operate in different contexts, and a certified tester needs to know how each one works. They need to know how to take apart the back how and put it back together so that they can make repairs or adjustments when needed.
Finally, you need to take a written test. If you pass this, then you are a certified back flow tester. You need to be re-certified every three years to ensure you are up to date. It’s a lot to go through, but it’s a good job that provides a lot of value to the community.
