I’ve got about 12 low flow emitters in my yard to water some potted plants. All work off the same sprinkler valve. After I adjust for the correct amount of flow for each emitter, the flow diminishes after a few days and then there is virtually no flow. To get everything working again I need to remove the caps, manually open the water valve and let air out of the system. Once water is flowing again I can adjust the flow rates again. This “air in the system” issue seems to be never ending. How do I prevent this?
As it stands now, when I go away on vacation, my plants are dead when I return home.
What you've described is fairly common with the adjustable emitters.
They have them at the Home Depot. Note the different colors have different gallons per hour.
