Riser Conversion Elbow

About:

The ½” female pipe thread x ¾” male hose thread Conversion Elbow is a simple and economical part used to convert a ½” sprinkler riser to a ¾” hose thread so that other components with hose thread can be used to start a drip irrigation installation.
Starting a drip system from an existing 1/2” riser
1. First, unscrew the sprinkler head from the riser.
2. Attach the ½” FPT x ¾” MHT conversion elbow to the riser.
3. Connect a 25 PSI preset pressure regulator with hose thread (model D46) to the conversion elbow.
4. To the pressure regulator connect a 3/4” swivel adapter (model C34). Use the ¾” adapter to connect to 1/2” drip tubing.
5. Secure the drip tubing to the ground using the tubing holder stake (model R60) and keep the end of the line open.
6. When combining drip irrigation with an existing sprinkler system, be sure to use a high flow drip emitter such as 4 GPH (model B224B) or adjustable drip emitters (BA1B, B10B) with flow rates of 0-10 GPH.
7. When the installation is completed, turn the valve on and flush the line. Then close off the end of the drip tubing with end cap (model Q58) or figure “8” hose end (model F68B).

NOTE: When connecting drip irrigation components make sure to use the correct threads. Do not mix hose and pipe threads, as they will leak
