The Eco-Indicator is a robust device that will indicate when the system is currently in operation. At 0.85 bar (85 kPa), the riser will pop up displaying a bright yellow stem. This commercial grade body attaches to either polyethylene or PVC through a ½” NPT connection thus avoiding ¼” tubing. This adds durability to the system that no other indicator can boast. When the system is not active, the Eco-Indicator will be in its retracted state and be flush to the ground.
