Main Line Behind 1 Green. . .

When the Superintendent first got here he asked me if there were any major irrigation issues. I mentioned the fact that there is very low pressure running to hole #3. This is one of the biggest holes on the course and we need it to have full pressure so we can water more of it at once. Last Summer I could only turn about six fairway heads on at once, while on other holes I could turn ten on. So we consulted with Jim Barrett who designed the irrigation and he recommended adding an additional main line to run water from #1 backwards to number five to number two. It is hard for me to describe without being able to show the irrigation map. Here are the pictures of the digging and existing pipes:

Let the digging begin

Tee dug up reveals a Harco fitting

A Harco fitting is made from ductile iron and it has a gasket inside of each opening so when you push the pipe into the opening the gasket seals it from leaking. Obviously these fittings are a lot stronger than a PVC tee and any pipes bigger than 2.5" you should use a Harco fitting.

The tee is going to be moved down about ten feet extending the 6" part of the pipe , so the Harco tee will be 6x4x4.

Where the new line is going to run, it will tee into line on 5(where backhoe is)

Unfortunately I was unable to get out and take pictures of them actually putting the pipes together. It's all finished and we are confident that it will increase the pressure to where we want it to be.
