Re:  RainJet sprinklers

I've used a self-installed RainJet system for five years, and I highly
recommend it.  The parts are sturdy, wear well, and are as easy to
install as possible considering you have to do a lot of digging...

Don't let a sprinkler system guru do all the design for you and then go
out and install what they design.  Odds are they'll overdo it by about a
factor of two, to insure coverage and sell hardware.  There's a big
learning curve, and the spare parts laying around attest to my trial and
error, but overall I saved money by learning, and then planning my own
system.  For example, no lines around perimeters facing inwards; large
squares in the center facing out are adequate (until trees grow in the
way, etc.  in which case you lay more heads as needed).

Keep accurate records of what you put in where -- distances to corners,
riser nipple sizes, etc.  You'll need them later to add sprinkler heads,
raise existing heads, etc.  A single scale map suffices.
