Note:I am not a writer nor a very good documentor, so if this needs some work please let me know, I have read dozens of instructables but never have been able to write my own, I just dont have the knack for it.
I am mostly writing this because I could not find another one like it on instructables, so count this as a springboard.
Step 1: Purchasing Materials
1 Rain Bird 2 1/2in Pop-Up Spray Head (whatever coverage area you want IE 90, 180 or 360)
4 3/4in 90's
2 3/4in Tee's
1 3/4in X
1 3/4 to 1/2in reducer (one half is what is on the bottom of my sprinkler head)
1 3/4 Slip x thread coupling
1 Package of hose washers (to keep it from leaking)
1 10foot stick of 3/4in pipe
A tape measure(optional)
PVC Pipe cutters
Personally I bought all of my materials at Lowes because I was there and they had all of the materials I need. (Nothing against Home Depot, LOL)
