What information do I need to get the correct size pump?

You need to have the elevation, distance to the furthest sprinkler head from the pump, gallons per minute needed, how many zones, and the size of pipe that you are using

Why isn't my pump producing enough water pressure?

The reason your pump is not producing enough water pressure could be the suction line, electrical, problems in the control or pump relay switch. A solution to this problem would be to determine if the amount of water (volume) and pressure on the discharge side of the pump is adequate to run the system.  Your footvalve may be clogged up with mud or incorrectly installed.

Why won't my electric valves open or close?

When an electric valve will not close it is usually due to an obstruction (sand, debris, etc.) which prevents the diaphragm from sealing or maybe a hole, crack, or slit in the diaphragm.

When an electric valve will not open, it is best to check the flow control (located on top of the valve) and make sure that it is open all the way, check to see if solenoid is operating correctly, check to see if there is adequate voltage from the controller to the solenoids.

How do I hook up the wires to my electric valves?

There are two wires that are on an electric valve.  Hook one of the wires up to the common wire and hook the other wire up to the hot wire (the wire for a specified zone)

Note:  it doesn't matter which wire is used for the connetions.

How do I set my Pro Plus/Dial-a-nozzle sprinkler head?

When setting the Pro Plus Sprinkler head you want to make sure that you have a K-Rain key (These usually come with the sprinkler head when you buy one).  First start by inserting the key  in the keyhole.  Then turn the key until the arrow on the sprinkler matches up to the degree that you need it at. 

To set the starting point for your sprinkler, pull up the riser from the sprinkler and turn the bottom portion of the riser to make your starting point (Note:  This can be done while the system in on)

When setting the Dial-a-Nozzle Sprinkler head you want to find the start position.  Then press your fingers around the ring between the top portion of the riser and the lower portion of the riser.  Then insert the key in to the keyhole and turn the dial until the nozzle that you need is in front of the arrow.

How do I set my R-50 Rainbird rotor sprinkler head?

When setting the Rainbird R-50 you want to ensure that the left fixed trip is where you want it.  This position is indicated by the double ribs on the body below the cap.  While sprinkler is up and operating, spread the vandal collar and slide it down the riser shaft (Do NOT remove the vandal collar).  You may add arc by turning in a clockwise direction.  Hold the riser in one hand.  With the other pushdown on the nozzle turret and while still holding down, dial the additional arc you need.  You may decrease arc by turning the nozzle turret in a counterclockwise direction (Note:  The sprinkler comes preset at 180°)
