Turn an underground sprinkler system into a low-flow drip system that waters eight individual plants with the Hydro-Port Adjustable Eight outlet Bubbler. The emitter has a 1/2 in. FPT inlet which connects to a 1/2 in. MPT sprinkler riser and eight out letting ports. Attach 1/4 in. supply tubing to each port to deliver precise watering. Ideal for garden areas and perimeter landscaping. Best used with a pressure regulator to lower water pressure and keep tubing in place.
