Irrigation Installation:

 

A beautiful green lawn is the first objective of any irrigation system but equally important is the investment our clients have made in bedding plants, shrubbery and trees. Each has its own unique watering requirements that must be taken into consideration when developing any irrigation system design.

 

GardenMasters will design a system that can meet each and every design challenge presented. We as professionals in the irrigation industry know the inherent strengths and weakness of many products manufactured today, a knowledge our customers appreciate.

 


Valve Boxes:

* Build your manifold before it goes into the ground.

* Install the valve box so the lip is just above ground.

* Use a valve box to protect wire splices and gate valves.* Add a gravel base below the box for drainage and settling.* Choose a color of valve box that blends with the landscape.

* Use a valve box to hide drip filter and multiple drip emitters.

* Space valves far enough apart to allow for Future servicing.* Allow enough pipe between each valve making sure it's long enough to cut out the valve later.

 


Sprinklers

* Maintain matched precipitation rates for each zone. (Don’t mix spray and rotary sprinklers)

* Avoid putting too many heads on one zone. (This causes poor head pressure and coverage)

* Don't mix combine zones if you can help it. (shady areas with sunny areas)

* Place grass, plants, and trees on seperate zones. (group plant types for each zone)

* Wind Considerations. (space heads closer together, if constant wind exists)

* Use swing joints on all heads. (This allows the spray head to move in different directions)

 


Wiring
* Add additional wire to each valve manifold for future needs
* Use waterproof wire connectors for connections to valves
* Use a common wire (white) for the ground to all valves
* 16-gauge wire is recommended, don't use small gauge
* Use direct burial wire from the controller to your valves
* Bury wire with the water main line to the valves

 


Q: What is the maximum distance I can run wire between the controller and the valves?

The answer really depends on the static water pressure of the irrigation system and the wire gauge you are using. Hunter Industries has provided a Valve Wire Sizing Chart to assist you with the correct wire size for your application.
