Now, go back and check your new misting system. Check for leaks, direction of spray and the distance of spray patterns. If you find a leak go back and repeat steps 1 through 3 for installing the fittings and the 1/2" Poly Tubing. Note: To change the direction of the spray simply turn the Mister to the desired angle. To change the distance turn the Mister Valve. At this point, if you wish, you can simply cover the tubing with mulch. We know you will enjoy years of efficiently watering your plants with our system.
