Sprinkler Head Layout
One of the main tasks of designing an irrigation system is the sprinkler head layout. The sprinkler head layout consists of deciding what kind of sprinkler heads will be used and where exactly they will be placed. When I do a layout I place flags in the yard representing where each head will go.
I continue to mark out the sprinkler heads, using different color flags for each individual zone. For example, the front right spray zone may have blue flags at each spot where a spray heads will be placed, a side spray zone may have orange flags, and a back rotor zone would have red flags.
Keeping each zone its' own color will help you with the building of your sprinkler system so that you don't mix the wrong heads on a particular sprinkler zone.
When laying out your lawn sprinkler system remember to not mix rotors and spray heads as I mentioned in my previous article. Rotors and sprays put out water at a different rate so you'll want to keep them separated.
Rotor heads typically throw 30 feet and can be reduced slightly if needed. Sprays can throw from 4 feet to 18 feet depending on what type of nozzle you use. Rotors can usually be adjusted from about 25 degrees to 360 degrees radius. Spray nozzles come in either fixed or adjustable pattern radius. I try and stick with fixed nozzles (ie. 15 half, 10 quarter, 12 full ect...) because they have a better spray pattern and don't tend to get clogged like the adjustable pattern sprays.
Overall the most important factor when doing a lawn sprinkler head layout is to make sure that you have "head to head" coverage. What this means is that the water from one sprinkler head reaches the next sprinkler head in the yard. This will ensure even precipitation and "double coverage" which is essential to a proper lawn sprinkler design.
So remember when designing out your lawn sprinkler system to make sure that you don't mix rotors & sprays, you have double or "head to head" coverage, and use different color flags to represent the different zones.
