Sub Surface Irrigation Drip Line Connection Assemblies


Component Assembly For Sub Surface Drip Irrigation Systems

Continuing with our Drip Zone Assembly we will now look at the components required for assembling the Supply and Exhaust Headers and the Drip Lines connecting the two. 

  • Water Source Connectione
  • Air Release Valve
  • Supply Header and Drip Line Connections
  • Exhaust Header
  • Zone Drainage

Supply and Exhaust Header Connection Assemblies.

Please Note:  The assemblies illustrated in this tutorial are for the actual drip line assemblies to the header and exhaust assemblies.  When connecting to your supply header to your main distribution line you may also need elbow and tee connections to navigate to the drip lines.  This configuration will be dictated by the layout of your property and are usually very simple to figure out.

Basics For Drip Line Installation  For Sub-Surface Drip Systems 

Emitter Installation Pattern and Spacing:  It is recommended to install drip line emitters in a staggered pattern to provide better coverage (see illustration below).  For spacing we recommend lines to be spaced 12" apart with 12" emitter spacing for good coverage.  

Installation Depth:  We recommend installing sub surface Drip Lines at a 4" depth.  This depth encourages root growth while also being deep enough to avoid being damaged by aeration equipment. 

Component Installation Options: As with other component illustrations there are several ways to install drip lines in a sub-surface turf irrigation installation.  We will now provide several examples using a variety of components, all of which work on the same principle.  We will look at connecting at 1/2 and 3/4" and larger distribution lines seperately.  As you can see from the illustration below we have also distinguished parts for either 12mm Techline EZ or 17mm Techline.

Connecting Drip Lines to a 1/2" Distribution Line - Mid Lateral Connection
Since all Male Adapters have male pipe thread all connection options must have a female pipe thread fitting for a proper connection.

** When using insert fittings using a gear or crimp clamp is recommended

Connecting Drip Lines to 3/4" and 1" Distribution Lines
Since all male adaptors have male pipe thread all connection options must have a female pipe thread fitting for a proper connection.

Additional Methods: In addition to the connection assemblies illustraed above it is also possible to connect the drip lines using 12mm Techline EZ or 17 mm Techline as your Supply and Exhaust headers using standard 12mm and 17mm Tee and Elbow Fittings found in the Techline Fittings Category. 

We will now look at completing the Sub Surface Drip Zone with a drainage valve.
