Backflow Prevention
In Pennsylvania, a water backflow prevention device is a requirement for buildings equipped with a fire suppression system, a large boiler, or an irrigation system. Also known as a Reduced Pressure Zone (RPZ), a back-flow preventer valve protects both your building’s potable water and the city water supply from contamination. When your building experiences a drop in water pressure, the backflow valve automatically dumps water from your fire, boiler or irrigation system, rather than allowing it to be pulled into your clean water supply.
How Back-Flow Occurs
Back-flow can occur when there’s a drop in water pressure either within your building or in a city water main. This drop in pressure is often caused by a leak in your building, a water main break, the use of a nearby fire hydrant, etc. When the water pressure drops below the pressure in your boiler system, fire suppression system or irrigation system, it can force the water from these systems to enter your potable water. This can introduce bacteria and sediment that’s been resting in your boiler or sprinkler system. Likewise, it can introduce pesticides or fertilizer from your irrigation system.
When contaminated water is pulled into your potable water system, the results can be hazardous. Naturally, this can lead to serious health problems – and costs.
