Design starts with pressure and flow
Before laying out heads we measure static pressure and available flow at the service. Those two numbers decide how many heads can run per zone. Overloading a zone is the most common reason an existing system leaves dry rings in the lawn no matter how long it runs.
From there we map zones by what is growing in them. Turf, shrub beds, trees, and containers all have different needs, and mixing them on one valve guarantees something is either drowning or crisping.
