Properly designed drip irrigation systems begin with what is called the drip zone or the drip zone assembly. The Drip Zone Assembly provides protection to the drip emitters and micro sprinklers from particles that may enter the system, and reduces or regulates the incoming pressure of the water entering the micro irrigation system to the appropriate operating pressure of 25 PSI, which is within the range of recommended operating pressures for a drip irrigation system.
A manual or automatic optional control valve (optional) may be added at the start a drip irrigation system. This assembly can be attached to a faucet, the most common method used to start a drip irrigation installation in home gardening. If using this option to start a system, begin the installation from an outdoor faucet (spigot). If you are planning to automate the system with a battery operated controller or a hose end timer connect the timer to the faucet first, before the backflow device.

About drip irrigation and the Drip Zone
Drip irrigation requires clean water and proper operating pressure. The cause of most drip irrigation system failures is either high pressure or clogged drip emitters; therefore a screen filter and a pressure regulator are the most important components in the micro irrigation system.
This drip zone kit provides the user with a complete kit that includes ¾ inch backflow device, ¾ inch 155 mesh screen filter, ¾ inch 25 PSI preset pressure regulator and a ¾ inch adapter with .700 OD to connect a drip zone to a 1/2 inch drip tubing installation .
The backflow device acts as a one-way valve, allowing water to move in one direction only and prevents back siphoning of non-potable or contaminated water into the water lines.
The screen T filterr is a simple and economical method for protecting a drip irrigation system. Periodically the filter screen needs to be cleaned by opening the filter cover, removing the screen, and rinsing the screen under water.
The 25 PSI preset pressure regulator is used to reduce and regulate the incoming pressure of the household water entering a drip irrigation or micro sprinkler system to the appropriate operating pressure range of 25 PSI, which is within the range of recommended operating pressures for a micro irrigation system.
The 3/4" FHT swivel adapter with .700 OD compression connection is used for the connection of a 1/2 inch drip tubing with .700 OD to any hose thread fitting with 3/4” male hose threads.
Connecting to a Faucet
1. Connect the 3/4" FHT x MHT backflow device to the faucet if not using with a hose end timer.
• Drip zone connection includes: ¾ inch 150 mesh T-screen filter, ¾ 25 PSI preset pressure regulator, and ¾ inch adapter with .250 OD compression for ¼ inch micro tubing
