My spray pattern has a blank dry spot in it. What should I do to correct this?

Mega spray heads have an adjustable ring that changes the flow rates and direction of the spray. Use this adjusting ring to control the intensity and geometry of your spray pattern. If that does not work, check the spray head assembly for debris and damage to the guide disc or lower housing. See image below for a demonstration of this.  If your problem persists please contact Mega Product Support for assistance and more information.
