What is Backflow Protection?
When you have any device connected to a potable water system, like a lawn irrigation system, backflow protection is essential. Think about it like this: you have a lawn irrigation system and if there were to be a city water main break, it would create negative pressure that would allow anything that your potable water system comes in contact with, to backflow into the system. Simply put, the chemicals you put on your yard with the lawn irrigation system could wind up back into the potable water system which is the water you and your family drink. A backflow preventor is designed to stop that scenario from happening. It acts as a containment device; it contains the hazard within the facility that it is protecting.
Residential Vs. Commercial Backflow Protection
A lot of people don’t come in contact with this backflow prevention in a residential setting, unless of course you have something like a lawn irrigation system as mentioned. Backflow prevention is mostly needed in commercial buildings, especially where highly hazardous materials exist. They are required to be tested annually by local jurisdiction. They must be tested by both a company that is licensed to test the system and the individual from the company that is doing the test must be
individually licensed as well. Reliable Drain is a licensed and insured company in backflow prevention, and we have four individuals that are licensed for testing and installation.
Are Backflow Prevention Devices Required or Optional?
Backflow protection is required to have in any sort of situation where backflow is possible. For instance, if you have a water-driven backup sump pump, you are required to have a reduced pressure backflow preventor to protect yourself and those around you. They are a local and state requirement and it is required that you test them annually.
