Step 3. Choose Your Components

Spray Head Installation

We’ve now basically laid down the groundwork for the system and we can now move on to the how to connect all these parts together. For this tutorial, we will be focusing on a few techniques that will make your life easier when installing your spray heads.

In-Line Spray Head Installation

The first thing we will look at is installing a spray head in-line, meaning the line continues to other spray heads. A good example would be head number 2 in our more Zone 1 layout and number 9 in our Zone 2.  

When we install a head in-line we always recommend the use of Dawn Quick Tap Saddles. Quick Tap Saddles eliminate the need for cutting the supply line and allows you to install a spray in head in minutes, if not seconds. We also recommend using Swing Assemblies (Specifically the SJ-506 from Hunter), and finally we recommend using a pressure compensating Spray Body (K78004-PR40).

Why Swing Assemblies? Swing Assemblies will allow for variances in tubing depth below the surface and also provide a certain amount of cushion for the spray head if for instance it was run over by a vehicle.

Lets take a look at a video of just how easy it is to install a spray body or rotor using Dawn Quick Tap Saddles.

Quick Tap Saddles can also be used when using Blu Lock Tubing.  We can also look at alternate installation methods.

From the above illustration and video you can see that the best practice is to have your T fitting facing upward to allow for easy maintenance. 

End of Line Spray Head Installation

Now we will look at installing Spray Heads at the end of a tubing run. Spray head number 1 in our sample layout is a perfect example. We will still illustrate the installation using the Hunter SJ-506 Swing Assembly. The basics for installation are the same, using regular black poly tubing or Blu Lock Tubing, just a few different fittings.

Although we have recommend using Swing Assemblies, you can also look at using ½” Nipple Fittings as a replacement for the Swing Assemblies.
