Proper system design and placement of valves is an intricate part of a good irrigation design.  Before installing an irrigation valve ensure you have a good irrigation design that follows your local and county building codes. 

Guidelines to follow when installing your valves:

When determining what might be the best valve for your particular needs, it is a good idea to keep these considerations in mind:

Choose a valve that will operate at the pressure available on the project. If your system will be subject to pressure surges or water hammer, the surge can be several times higher than your static pressure (for large projects, it's best to choose a valve with a higher operating pressure). A valve with a 200 psi (13.8 bars/1378.96 KPa) rating will provide the best long-term performance.

The Hunter Flow Sensor body (FCT or Flow Clik Tee) is designed in diameters from 1" to 4"(2.54-10.16cm). It is installed into the mainline of the irrigation system, near the point of connection. It is important to install the Sensor Assembly (FCT + HFS) downstream of the master valve. Also, it is necessary to install the Sensor Assembly in an area of low turbulence within the system. Areas of high turbulence will cause erratic readings from the Flow Sensor.

Hunter's ET System has a wind option that utilizes an anemometer to read local wind conditions. In some cases site conditions may require the anemometer to be located away from the ET Sensor. If this is the case, using 18AWG wire the anemometer can be mounted up to 100ft (30.34m) from the ET Sensor.

To simplify setting up a Hunter ET System we've highlighted some of the more complex choices.

Note: The ET Module dial must be left in the Automatic position, or the ET program will not irrigate! If the ET System is watering, moving the dial from the Automatic position will cause it to stop.

The I-90-ON is now compatible with Hunter PGP nozzles, the opposing nozzles and the mid and short range nozzles can now be outfitted with normal PGP nozzles.

Now that there are multiple options and configurations of nozzle pairings, each nozzle's precip rate will have to be taken into consideration. A total precip rate for all nozzles will no longer be accurate.
