Rain Bird RCKIT-1PS Drip Irrigation Conversion Kit. Convenient kit converts underground sprinklers and 1/2” risers to water-saving Drip irrigation. All-in-one unit provides 30 PSI pressure regulation and 200-mesh filter screen for optimal Drip system performance. Saving up to 80% over sprinkler watering, Drip systems apply water directly to the root zone for healthier plants. In most instances, owners of Rain Bird 1800 Series pop-up sprinklers will make the conversion without digging. Kit will replace all pop-up sprinklers with a 1/2” threaded bottom inlet. If you have another brand dig out and remove old sprinkler and thread kit to existing 1/2” male fitting. Easy Fit Tee tubing connector allows for assembly to any 1/2" or 5/8" Drip tubing. Constructed of highly durable UV and chemical-resistant materials to assure long life. Requires capping other heads on the zone. Inlet pressure 15 to 70 PSI.
