WASTEFLOW® HEADWORKS INSTALLATION

  1. Your WASTEFLOW Headworks components may come loose in shipping and handling. Please tighten all threaded connections prior to installation.
  2. Provide a minimum of 3" gravel beneath the WASTEFLOW Headworks. Install the box below grade.
  3. After installation close the two valves in the WASTEFLOW Headworks box and pressurize your Geoflow subsurface drip system. Once the system is fully pressurized, check the pressure gauge in the WASTEFLOW Headworks box and be sure it is less than 60 psi. The optimum pressure range in the subsurface drip field is 15-45psi.
  4. In freezing climates be sure to:
    a. Insulate the box. Use closed-cell insulation that can easily be removed such as perlite in a plastic bag.
    b. Mark the valve box with a metal pin so it can be found when covered with snow.
    c. If using manual WASTEFLOW Headworks, make sure field flush valve and filter flush valve are cracked open slightly to allow drainage.
    d. If using automatic WASTEFLOW Headworks, make sure controller is set to leave field flush valve and filter flush valve open after pumps are turned off to allow drainage. This is the default setting for Geoflow¹s Geo controllers.
  5. Solenoid valve operation:
A
Manual bleed lever

Operating normally lever should always be in the horizontal position.

- Horizontal position

Solenoid port inside is closed unless opened electrically.

- Vertical position

Solenoid port inside is always open and water flows through the valve.

B
Flow control

When operating the valve the flow control dial should be free spinning and adjusted according to flow demand.

If the valve is not closing or slow closing, turn dial clockwise to reduce flow.

If the valve is not opening or delivers low flow, then open the flow control dial counterclockwise. Clockwise rotation closes valve.
