What Is Backflow and How Does It Happen?
Backflow occurs when non-potable water from a sprinkler system flows back through the pipes and potentially contaminates the drinking supply. It is clear why it is very important to address backflow with your fire protection in Tucson.
Backflow happens in one of two ways. When downstream pipe pressure goes higher than the supply pressure of the pipe system, you get back pressure — and backflow can occur. If the supply pressure goes below the water system pressure, you can also get backflow. This type of backflow is called back siphonage.
How Do You Test for and Prevent Backflow?
You cannot test for backflow on your own. You will need a qualified backflow inspector to test your system to make sure it is operating properly. The backflow professional shuts down the water supply and visually checks to make sure the water is flowing the right way, then employs a test kit to verify the condition of the system.
If you have a backflow problem, you need to install a backflow preventer. This creates an air gap that stops contaminated water from collecting and flowing the wrong way. Your fire system professional can help you choose the right backflow preventer.
You may opt for a double-check assembly for your Tucson fire prevention system. This is an all-purpose valve that protects you from both back pressure and back siphonage.
You may also choose a reduced pressure zone assembly. This is the standard backflow preventer for apartment buildings, since they provide maximum protection against contaminating backflow. Another possibility is the pressure vacuum breaker assembly, which is a spring-loaded system you use in high-hazard situations with downstream valves.
