Sprinklers not filling Large Planters

Using a pump to run water to sprinklers, all works well at first. Then randomly some of the planters stop receiving water. During this failure the sprinkler indicates that it does have water, the animation indicates that it is running, and I get "Wet" while standing there. But the planter water level does not change.

Temporary fix:

1. Remove the hose connection and reconnect it. The planter will start to fill with water immediately.

2. Wire all pumps into a switch and cycle the power for several seconds, then all will come back to normal.

This does not seem to be a "Sprinkler" issue, but more of a "Planter" not realising it is getting wet. As mentioned above, at the time of failure, the sprinkler has enough water to run the sprinkler (minimum 2), the sprinkler animation is working, and when standing next to the sprinkler you become wet. All indicating that the sprinkler is operating normally.
