Similar to a sprinkler head, the Eco-Indicator pops up to provide visual indication that a drip system is operating.


The Automatic Flush Valve (AFV) allows debris to be flushed out of any dripline system.

  • It is good practice to install an AFV at the end of any single dripline or grid of dripline.
  • Flush the zone prior to use. 
  • An AFV may be used for any dripline system without check valves and will flush the line every time the system starts. Install after initial system flush.



Some of the features of the WVP include:

  • Simple, push button programming
  • Large Liquid Crystal Display (LCD) with easy to under- stand icons
  • Radio communication WVC controllers up to 100 feet away
  • Operates on standard 9-volt alkaline battery
  • Days-of-the-week watering schedule
  • Up to 9 start times per day
  • Run times from 1 minute to 4 hours
  • Manual watering
  • Low battery status shows status of life of the battery in the WVP and WVC

The system off function will turn your WVC controller off, stopping all automatic watering until turned back on with your WVP.


This feature permits the user to stop all programmed watering for a designated period from 1 to 7 days. At the end of the programmable rain off period, the controller will resume normal automatic operation.



All program information and manual watering is conducted with the WVP and individual WVC controllers using radio signals. Under normal conditions, these operations can be conducted up to 100 feet from the controller. The Transmit/Receive button on the handle of the WVP is used to establish radio contact to transmit and receive data.  It is recommended procedure to first retrieve the program from a WVC, review and make necessary changes, and then transmit the new program back to the WVC.


Even if you have drained the water out of your irrigation system, some water remains and can freeze, expand, and crack PVC piping (rigid, white pipe). Polyethylene pipe (flexible, black pipe) is used in many freezing climates. Although polyethylene pipe is more flexible and can expand under pressure, water left inside can freeze and rupture the pipe walls. Freezing water in the backflow assembly will damage the internal components and can crack the brass body.


The Cycle and Soak feature allows you to split a station’s run time into more usable, shorter watering durations. This feature is useful when applying water to slopes and tight soils because it automatically applies water more slowly, helping to prevent runoff from occurring. You should enter the Cycle time as a fraction of the station's watering time, and the Soak time as the minimum number of minutes required before watering can occur again for the next Cycle. The total number of cycles is determined by taking the total programmed station run time and dividing it by the Cycle time.


REL 2 is used to allow multiple controllers to operate the same low-voltage device

(Master Valve or Pump Start Relay). 

IMPORTANT: REL 2 is NEVER connected to high voltage. It is for 24VAC devices, only.
