Low pressure sprinklers everywhere I have an eight sprinkler system using 4" Hunter popups to cover 700 sq ft. This is tied directly into a hose bib. How can I increase the irrigation system pressure without adjusting the main water valve and increasing water pressure for the entire house? Zone 10a, 90%TFFF 10%KBG TIA!
