Irrigation and Fire Sprinklers Backflow Test

A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow.

In water supply systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, pipes freeze, or there is unexpectedly high demand on the water system (for example, when several fire hydrants are opened). Reduced pressure in the pipe may allow contaminated water from the soil, from storage, or from other sources to be drawn up into the system.

Backflow means the undesirable reversal of flow of a liquid, gas, or suspended solid into the potable water supply; a backflow preventer is designed to keep this from happening. Points at which a potable water system connects with a non-potable water system are called cross connections. Such connections occur naturally in appliances such as clothes washers and dishwashers, but they must be carefully designed and installed to prevent backflow. Another common location for a backflow preventer is the connection of a fire sprinkler system to a water main, to prevent pressurized water from flowing from the fire suppression system into the public water supply.

Backflow Test Includes:

  1. We would fax the Backflow Test Report to the water district
  2. We would clean the Backflow device if it fails at the initial test to determine if the device needs new parts or needs to be replaced (Note: we would clean any device that has enough room to work on it and no bigger than 2” in size)
  3. We don’t charge for cleaning the device, only if the backflow assembly needs new parts or needs to be dig out (irrigation backflows)

Backflow Test Pricing:

$45-$55 (depending city location and backflow device size)

Note: Prices varied for any Backflow Assembly Test bigger than 2” in size.
