About this task

Before you start equipment, manually flush the valve to remove any foreign material from the valve.

Procedure

  1. Turn the adjusting screw clockwise, to raise the adjusting screw away from the valve body as much as possible. See Figure 1. Count the number of turns for reference.
  2. Insert a standard slotted screwdriver tip between the adjusting screw and the push pin.
  3. Pry the push pin down with the screwdriver to open the valve as indicated.
  4. Hold the push pin down to hold the valve open. Flush the valve for several minutes, to remove all foreign matter from the V43/V243 valves.
  5. After you flush the V43/V243 valves, remove the screwdriver and set the adjusting screw to the desired operating pressure. See Adjusting the valve.
