Without clean water, the filters in your Irrigreen Sprinklers can acquire excessive amounts of debris and restrict or prevent watering.

If you have particularly dirty water (well or canal water), installing a 100 Mesh (150 micron) filter with your system is required. If you need more information on well systems and Irrigreen visit: https://support.irrigreen.com/en/installation/wellsystems

Tip: You can add a solenoid valve to your filter, wire it to the controller and schedule it to run as a valve zone to create a self-flushing version and avoid cleaning the filter constantly.

Measure with a pressure gauge. If using a diaphragm pressure gauge and it is fluctuating, you have dynamic pressure. All irrigation requires constant pressure, you may have to consider a pressure regulating valve (PRV) or a constant pressure system.

Note: The Irrigreen XP Sprinkler Heads have a pressure sensor that can make up ~5-10 PSI of pressure fluctuation. Measurements must be taken even with XP, if you do not meet our requirements your system is likely to underperform.

Measuring flow is just as important as pressure. Flow is the volume of water moving in the pipe over a certain amount of time (measured in Gallons Per Minute [GPM]). A flow meter can be purchased and ran with your system, though not required.

To measure your flow, bring a 5-gallon bucket to the water source. Place bucket underneath the faucet and turn on the water (avoid frost freeze faucets).

Record the time it takes to fill up the bucket. If you can fill the bucket in under 45 seconds, then you have the recommended amount of flow.

Exact placement is not critical as you can
program each sprinkler to the shape of the zone.

Using a tape measure, measure from the rough center of your zone to the farthest corner to make sure you have enough watering range to reach every part of the zone.

Considerations for placement:
• Don’t overlap sprays or zones.
• Place 1 sprinkler per zone.
• Place sprinklers so that they can reach your furthest corners.

NOTE: Refer to the PSI/distance chart before placing heads. The farthest corner is the longest distance on the zone. This chart assumes you meet our requirements of 8+ GPM at the head location. Less than 8 GPM will result in shorter throws, likely maxing out at 15-20'.

Example of two zones:

Check minimum throw distance (cannot be less than 5 feet).

NOTE: Sprinklers cannot be programmed to distances less than 5 feet, to keep the head riser from retracting.

• Place sprinkler along the edge.
• Sprinklers can be programmed to water in a 180° pattern, or other patterns.
• The 5 feet minimum throw distance ensures that the sprinkler has enough pressure to stay popped up. Good practice is to start with the furthest distance to allow the head to get as much pressure as needed initially.
