Rain Bird 1804APPRS four-inch spray heads, four-pack
Four pressure-regulated, four-inch pop-up spray heads with adjustable pattern nozzles.
Replacing a few tired spray heads is a useful moment to straighten the whole zone. Match the four-inch body to the installation, set each head level, then adjust the arc to the lawn edge. Walk the zone while it runs so you can catch overspray and dry patches together.
