MIXC 100PCS Drip Emitters Sprayer with Stake Water Flow Adjustable for 1/4 inch Irrigation Tube Hose, 360 Degree Dripper Perfect for Irrigation System Watering Kits for Garden Patio Lawn Flower Bed

Features of these drip emitters with stake: *Ajustable water flow rate from 0-9 gallons-per-hours *Ajustable spray diameter from 0 to 20 inch *Height increase to 7 inches, higher than other products How many heads can be installed on a single 1/2 inch line? This depends on the line pressure, the further from the start of the line the water pressure will drop off. Adjust the flow rate of every emitter to ensure that all of them have water. How to add these emitters to my exist watering system? Create your lateral lines(1/4 inch tubing and couplings) BEFORE hooking them up to the main line. You also can punch a hole in the main line and insert the emitter to it directly. Please Note That: Make sure the hose is softened before connecting. Soak end of 1/4" tubing into HOT water before attaching to the drip emitter. I would recommend filling a thermos with boiling water to dip your 1/4" hose into as you assemble your lines.
