Properly designed drip irrigation systems begin with what is called the drip zone or the drip zone assembly, which consists of three vital components: the back-flow device to prevent contamination from back-siphoning into the water supply, a filter to protect the drip emitters, and a pressure regulator to lower the pressure to the suggested operating pressure for a drip system. This assembly can be attached to a faucet, the most common method used for 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 (optional) (not included), connect the controller to the faucet first, before the back-flow device.
The first component needed is a back-flow device, which you attach to the faucet. (If your faucet already has a brass back-flow device as part of the faucet, an additional back-flow device is not required). Next, attach the filter, and then the pressure regulator.

Next, select which type of fitting to use to continue the drip zone installation. With installation from a faucet, the 3/4" swivel hose thread, sealed by a washer, is included to connect the drip tubing to the drip zone assembly. This 3/4" swivel adapter should be threaded to the pressure regulator, clockwise and "hand tight" only. Tightening with a wrench is not recommended and is usually not necessary using hose thread fittings. This completes the drip zone assembly.

Installation for 3/4" x 1/2" Drip Zone Assembly

Starting the irrigation system from a faucet:

·         Optional: If you wish to automate the system, first connect a hose end timer or battery-operated controller to the faucet, if a backflow device is used, connect the timer or controller after the backflow device (suggested controller model).

1.       Connect the 3/4" FHT x MHT backflow device to a timer or controller or directly to the faucet if not used with a hose end timer or a controller.

2.       Connect the 3/4" FHT x MHT T filter to the backflow device if used or directly to the controller male outlet or faucet if the backflow device is not used.

3.       Connect the 3/4" FHT x MHT 25 PSI pressure regulator to the filter.

4.       Connect the 3/4" FHT swivel adapter to the 3/4" FHT x MHT 25 PSI pressure regulator.

5.       To start the drip system, connect the poly drip tubing to the adapter by wiggling and forcing the drip tubing into the compression side of the adapter and then.

6.        Lay out the drip tubing to the garden area. The 1/2" drip tubing is used as the main line for drip systems into which drip emitters, micro sprinklers or 1/4" micro tubing are inserted 

Make sure that the water flow direction in each component is in line with the water flow of the system.
