Last summer the sprinklers worked fine but when trying to replace them with drip we found the water no longer flowed. I opened the pressure regulator to inspect if it was blocked but it seemed fine. I can hear the gurgling of water when I turn on the system either with the actuator or manually. But water just barely flows out and only at the first sprinkler outlet. There may be some dirt or stones in the pipes. Is there any way to clear out the pipes without water pressure? Or how can I troubleshoot the lack of pressure?

  • No, it's quite warm. – Reed G. Law Mar 31 '19 at 15:32

  • No. We capped most of the sprinklers while working on the yard in preparation for installing drip conversion kits. Now the water just barely comes out at the first uncapped outlet. – Reed G. Law Apr 1 '19 at 0:06

    I can advise you to pull-out one dripper at-a-time while the tap is on. See if water rushes-out when you do it. There is a chance (I raise it as a possibility) that you have let-in some soil or other dirt and clogged the system somewhere along the way. – Christmas Snow Apr 1 '19 at 17:57
