Irrigation System Control

In addition to the landscapers, the Landscaping Committee has 2 members who regularly inspect the irrigation system and look for issues. This page has the information pertinent to that process.

Backflow Preventer

  • The "backflow preventer" is located at the corner of Crown and Queens.
  • The backflow preventer valve is basically the main shut-off for the entire irrigation system.
  • Shutting down the entire system is an action not to be taken lightly, but it is the point of control should there be a major break in the irrigation system.
  • Once the system is shut-down, the start-up should most likely be handled by the landscaper as it is an old system and must be started up gently.
  • The backflow preventer was tested and certified on August 31, 2016.

Turning Off Water

  • The control valves are located behind the road sign for Crown Drive and Queens Road.
  • There are 2 blue handles. The one labeled #2 controls the main water flow. The other one controls the irrigation system.
  • If a Landscaping Committee member shuts down the entire system, it will cost additional to have the landscaper respond, particularly if it is weekend or after hours. If leaks in the irrigation system are discovered, it is possible to isolate specific regions or areas and shut them off at the control panels.

Controller Boxes

There are 3 control panels, each of which irrigate separate areas of the property.

  • Controllers A and B are located close to the fence near the backflow preventer valve at the corner of Crown and Queens.
  • Controller C is located in the walkway between #1310 and #1314 Crown near the Green Space.

Each of the Controllers has 2 programs:

  • Program A: Controls the Turf Areas
  • Program B: Controls the Shrub Areas

The Landscaping Committee members who are designated to keep tabs on the sprinkler system have a complete set of keys to the controllers. These are kept on a hook in their garage. If they are away for a period of time, a pet-sitter will have access to their home and garage and can get the keys when necessary.

The are Clock Setting Sheets (A, B, C) show the program run times for the individual valves.

 

Maps

  • There is a color coded map for each of the Controller Boxes that shows which areas are turf and which are shrub.
  • In each Controller Box is a detailed sheet that contains more detailed information for the landscaper's use in analyzing areas and times.
  • The actual Controllers are old but have digital displays and a main dial that allows you to change the display to view various program settings.
  • Below the digital display, each Controller has a junction box to which wires are attached and then routed to valves throughout the irrigation system.
  • Each Controller Box has a 9 volt battery that is changed yearly to retain the programming in case of power outage.
  • The metal Control Box Cabinets are old, and the locks not easy to work but they are functional. You have to tightly squeeze the doors to the cabinets to be able to lock them, but they are certainly usable. The interior panel locks were not as difficult but again, older equipment and usable but have to fiddle to get them unlocked and locked.

  • The Control Box B cabinet is a little wobbly, will try to get it a little more stable with a few rocks or stakes.

Operational Notes

  • The rotating sprinklers in the turf areas have an inherent tendency for the internal sprinkler head to shift it's orientation over a period of time; hence, we sometimes see those sprinklers watering where they shouldn't, like watering the parking areas adjacent to the turf. The landscaper just has to be notified of this and they will correct accordingly.
  • The landscaper does semi-annual checks of the entire system. They manually turn on each valve and observe each sprinkler head to make sure they work, are not leaking, and are set for the proper direction of spray etc.

Original Drawings

These drawings are quite cluttered but do represent what the original developer specified. They are from The Crown Harbor Project by Ponderosa Homes. Peter Callander was the Landscape Architect.
