How to choose sprinkler nozzles for uniform lawns
Nozzle choice drives real distribution quality. Pick radius, arc and precipitation compatibility carefully.
Sprinkler body vs nozzle
The body pops up; the nozzle defines distribution pattern and output. Many coverage issues are nozzle-selection issues.
Matched precipitation rate (MPR)
Within one zone, nozzles should have matched precipitation so different arcs still apply compatible mm/hour.
Real radius depends on pressure
Catalog throw distance assumes test pressure. Verify real field pressure before final nozzle selection.
Practical sizing by lawn scale
Small lawns use short-radius spray nozzles; medium lawns often benefit from rotators/rotors with longer throw.
Mistakes during replacement
Increasing nozzle size without rechecking zone flow can collapse pressure and degrade entire-zone performance.
