Problem: My Mister won't spray!
Solution: Occasionally, during installation, the Mister and/or Violet Flow Controller may become clogged with debris. Use a small paper clip, needle or the Mister Landscaper All-In-One tool (MLA-TOOL) to unclog the Mister's orifice. To clean the Violet Flow Controller, simply twist the two halves apart, clean it (be careful not to lose the diaphragm), and then rejoin the two halves. You may also experience clogging if you have hard or dirty water. In this case, the cleaning procedures are the same. However, to prevent future clogging, use the Mister Landscaper screen filter (MLFF-41).

Problem: The Backflow Prevention Valve is leaking!
Solution: The Backflow Prevention Valve was designed with relief holes to reduce pressure and prevent water from flowing back into the pipes once the water is shut off. When the water supply is turned off at a faucet, negative pressure or a vacuum is formed. Without the Backflow Prevention Valve installed, water can be suctioned back into your pipes. With the Backflow Prevention Valve, when this water is pulled, it is allowed to flow out the relief holes and not back into your home. This is completely normal and nothing to worry about.

Another cause for a leaking Backflow Prevention Valve is incorrect placement. If the valve is mistakenly placed before a timer, and the system is not active, water will leak from the relief holes. Because a faucet must be left open for a timer to work, too much pressure is placed on the valve. If a timer is used, it must always be installed first. This is then followed by the Backflow Valve.

Problem: My Pressure Regulator is leaking!
Solution: Both the 25 and 50 PSI Pressure Regulators are designed with a single air vent in the side of the casing. This air vent allows a diaphragm inside the regulator to function correctly. Typically, the only time water would leak from this hole is if the regulator has been installed in the wrong order. If a regulator is installed before the timer, the pressure build-up can be too great when the system is not running and can cause the air vents to leak. If a timer is used, it must always be installed first. This is then followed by the Pressure Regulator. On rare occasion, dirt or debris might get caught up in the diaphragm. To clean it, simply remove the pressure regulator and backwash using a hose.

Problem: My Pressure Regulator doesn't reduce pressure!
Solution: The Pressure Regulators are designed to reduce pressure ONLY when the system is running. So if, by chance, you test the Regulator with a pressure gauge and get a reading higher than expected, it's because water is not being allowed to flow continually through the regulator. If a gauge is placed directly after the Pressure Regulator, the flow of water stops at the gauge, the Regulator's diaphragm opens and the pressure is equalized on both sides of the device. Thus, giving a reading consistent with the home's normal water pressure.
