What should you determine before starting the layout of a residential irrigation system?

  1. Pipe material

  2. Area dimensions

  3. Static water pressure

  4. Water source location

The correct answer is: Static water pressure

Before starting the layout of a residential irrigation system, it is important to first determine the static water pressure at the location. This is because the pressure of the water supply will affect the design and functionality of the system. Option A, pipe material, can be chosen after determining the static water pressure as it needs to be compatible with the water pressure. Option B, area dimensions, may be important but it is not the most crucial factor to consider before starting the layout. Option D, water source location, is also important but can be determined after knowing the static water pressure.
