Gear Driven Pop 3/4"

A 3/4-inch pop-up sprinkler is an underground irrigation head designed for medium-to-large landscapes that features a 3/4-inch female threaded bottom inlet to connect to underground water supply pipes. When the irrigation system is turned on, internal water pressure forces a spring-loaded riser to "pop up" above the lawn surface; when the water is turned off, the riser automatically retracts flush with the ground, staying hidden from lawnmowers and foot traffic.
