Question
I installed a rain jet sprinkler system in my lawn about 28 years ago.  One of the T connections for a 1/2 riser has split out.  Where can I get a replacement for Rain Jet lawn sprinkler parts?  

Answer
There should be an irrigation supplier near where you live, the kind that sells to contractors. John Deere Irrigation is one, Ewing irrigation is big in the West.  Try calling them, but dont be surprised to find that no one has those parts.  Also try this link:
