How to measure water pressure for irrigation
Pressure determines sprinkler radius and zone capacity. Measure it first to avoid design mistakes.
Pressure is your starting parameter
Catalog radius values assume specific pressure. If your real pressure is lower, coverage drops and gaps appear.
Typical home values
Residential supply is often around 2-4 bar, but dynamic pressure under flow is what matters for design.
How to test
Use a hose-thread pressure gauge and also measure flow with a bucket test. Pressure and flow together define your real zone capacity.
Account for pressure losses
Pipes, fittings and valves reduce pressure along the line. Design with safety margin so end sprinklers still operate correctly.
