Fire sprinklers need to be tested to ensure water supply safety

Fire sprinklers are complex systems designed to protect life and property from a fire. But the complexity of their mechanisms, as well as the fact that they are connected to the municipal water supply poses some unique challenges. One of these challenges is the dangers of backflow and the need for a properly functioning backflow prevention assembly system.

A fire sprinkler system connects to a cross-contamination system, which is where water from various clean sources connects with contaminated or polluted water sources. For example, when a fire sprinkler system connects with a public water source, there is a crosscontamination system connecting them.

The water in a fire sprinkler system, as well as most potable water systems, is designed to maintain a constant level of pressure to ensure that it is ready to flow efficiently whether out of fire sprinklers, faucets, hoses, etc.

Backflow occurs when water pressure unexpectedly changes or drops in the municipal water supply. This allows a reverse flow of water from a contaminated water source into the clean, potable water. A backflow prevention valve prevents backflow in the event of dropped or failed water pressure. The backflow prevention valve can be installed in the fire sprinkler piping where there is a risk of contaminated water in the sprinkler system flowing back into the municipal water supply should water pressure drop.

If the City of Batavia’s drinking water supply were to be contaminated by backflow from a fire sprinkler system, it could endanger the health of those drinking from the water supply. Therefore the City of Batavia requires the backflow to be inspected and tested annually by a qualified professional who is certified in testing backflow devices.
