how to use

Drip System Flag Indicator


To minimize the question of “not sure that my drip system is on”, DIG provides a simple solution with the 8” Pop-Up Flag Indicator. Install the 8” Pop-Up Flag Indicator with one per zone at the highest point or in the most easily viewed area in the garden, and when that drip zone is activated it will provide a visual indication that the zone is pressurized and working. The pop up indicator will emit a small amount of water as it rise, to lubricate the piston, and when the system is pressurized, a red indicator cup will be raised to indicate the system is running.

Installation to drip tubing

Mount the pop up in most easily viewed area in the garden, into1/4” micro tubing not to exceeding 2’ to 4’ in length:
1. Cut a length of ¼” micro tubing and connect the end of one side into a ¼” barbed connector (model H80A for pack of 5 or H80B for pack of 50) by forcing and twisting the micro tubing over the barb.
2. Connect the other end of the micro tubing into the ¼” barbed elbow mounted on the lower part of the pop up indicator. The micro tubing is forced over the pop up indicator barbed elbow - no glue is needed (the barbed elbow is press-fit type and it can be removed from the pop up assembly)
3. Punch a hole into the side of the drip tubing and insert the 1/4" barb into the drip tubing.
4. Mount the pop-up indicator about 4”-5” above the ground in a visible area between the plants.
