What is the purpose of flushing pipes before installing sprinkler heads?

Flushing pipes before installing sprinkler heads is crucial primarily for removing debris that could clog the heads. During the installation of irrigation systems, dirt, sediment, and other particles can accumulate inside the pipes. If not flushed out, these contaminants can enter the sprinkler heads once they are installed, potentially leading to blockages that hinder water flow, affect coverage, and ultimately reduce the efficiency of the irrigation system. Flushing ensures that the sprinkler system operates correctly from the outset, minimizing maintenance issues and ensuring optimal performance.

Other purposes listed, while they may appear relevant, do not directly address the fundamental need to ensure that the water delivered to the sprinkler heads is free of obstruction. Proper filtration and water flow management are indeed important, but they are secondary to the immediate goal of clearing any potential blockages created during installation.
