Maintaining backflow prevention devices is critical for the health and safety of everyone! Local water districts as well as the health department have gone to great lengths to ensure that the city provide safe drinking water. It is required that backflow prevention devices be tested at least once a year and that they pass the minimum federal requirements.

Fire Safety First tests all serviceable backflow prevention devices, from irrigation to main fire lines. If you have received a notice from your local water provider call Fire safety First. With highly trained testers, Fire Safety First is an expert when it comes to backflow prevention.


Fire Safety First's certified and knowledgeable technicians have the ability to test, service, and repair any backflow device that you have on your property

Fire Line backflow devices are installed on fire protection systems and – even though these are “non-flowing” installations – it is not as simple as shutting down the valve to test or repair the device. Alarm monitoring systems need to be put on test or fire pumps need to be turned off for backflow testing or repairs. Alarm panels may need to be reset after completion and alarm monitoring must be taken off test mode. The monitoring systems ensure that all control valves are returned to their proper position. Since these are non-flowing systems a shut control valve would not be noticed until there is a problem. The reason why the vast majority of fire sprinkler systems fail is because someone shut down a water supply valve and forgot to open it up again.
Domestic backflow devices are typically installed to isolate any potential problems from getting back into the water purveyor’s piping. This will cause the water purveyor to mandate a backflow device be installed as close as practical to the water meter, ensuring no other possible cross connections between the meter and backflow device. Domestic backflow devices need lots of coordination to test and repair. There may be pumps to turn off or shutting down water, just for a few minutes to complete an annual test, can cause problems on systems that are using water. Many test and almost all repairs are completed after hours or during a time that water is not being used. For this reason, Fire Safety First highly recommends installing two backflow devices in parallel, ensuring uninterrupted domestic water usage during testing and repairs.
Industrial water is typically a piping system to serve a variety of non-potable water use within a facility. You can install one backflow device on a dedicated industrial water system versus having multiple backflow prevention devices every time you want to connect to the potable water piping to supply water for a machine or processes. Industrial water backflow prevention devices have the same testing requirement as any other backflow prevention device. As with other systems that are using water, coordination needs to take place with building maintenance personnel to shut down an industrial water line for backflow prevention testing or repairs.
Backflow prevention devices on irrigation systems are the easiest systems to deal with. Testing and repairs can be accomplished at almost any time without disruption. Irrigation systems do however require the highest level of protection when it comes to backflow prevention devices. This is because irrigation can have fertilizers and herbicides injected into them, making them a serious “contamination” hazard. Most of the time a water purveyor will require a reduced pressure principle backflow preventer.
It is unusual to have backflow prevention devices on a reclaimed water system. This is because reclaimed water systems are not connected to a water purveyors potable water piping. Reclaimed water piping is its own piping system not connected to anything else, so backflow prevention devices are not required. You will occasionally find some type of backflow prevention device on a reclaimed water system, this is usually because a water purveyor does not want their system contaminated, but it has nothing to do with protecting the public health. The most concerning issue is not to use a backflow prevention device testing gauge to test both potable and reclaimed devices as you have the potential of contaminating potable water piping. Once a gauge is used on a reclaimed water piping that testing gauge will be used for no other testing except for a reclaimed water service.
