Once you have selected all your sprinklers you will need to split the sprinklers into zones. This has to be done because it is unlikely that you will be able to run all the sprinklers at once, unless you have a very small yard. You will need to have one valve to control each zone. It is best to locate the valve manifolds in an easy to access location for when service/maintenance is required.
Things to Consider When Separating Sprinklers Into Zones
- Do not mix sprinklers with sprays
- You will want to match the precipitation rates
- Once grouped into zones, starting at the sprinklers use the smallest pipe size required to support the water flow for the sprinkler. As you connect the pipes that feed the sprinklers to your mainline make sure that you are up sizing the pipe as required to meet the combined flow rate for the sprinklers downstream.
