====== Loss of Pressure ======
In the event that the system is no longer pressurized, the [[components:valves:blowoff:division_two_blowoff]] needs to be opened to allow air to escape the system and to avoid stresses on the system.

<WRAP center round important 60%>
If the booster pumps are off for an extended period of time (for maintenance, power outage, etc...) and the [[components:gauges:mains_pressure_gauge]] reads 0 or close to 0, it is critical that the [[components:valves:blowoff:division_two_blowoff]] be opened before the booster pumps are restarted.

  - Ensure both [[components:pumps:booster_pump_left|]] and [[components:pumps:booster_pump_right|]] are turned off at the [[components:controls:control_box|]]
  - Ensure that the all [[components:valves:main_shutoff|]] valves are open
  - Open the [[components:valves:blowoff:division_two_blowoff]]
  - Put one of the booster pumps into manual mode
  - Let the booster pump run for at least 10 minutes, the water coming out of the blowoff should be steady, no sputtering or air.
  - The [[components:gauges:mains_pressure_gauge]] should show some pressure now.
  - Slowly close [[components:valves:blowoff:division_two_blowoff|]]
  - Set the booster pumps to auto
  - Monitor the [[components:gauges:mains_pressure_gauge|]] and the pressure gauge in the control box. It should return to 20 psi
  - The booster pump set to auto should automatically shut off when the system reaches ~22 psi
