Orbit Sprinkler System Designer specifies Poly Pipe for all mainline pipe and connections after the source
connection up to and including the valve manifolds (the valves control water flowing to the individual areas or
"zones" in your yard).
Poly pipe has many good qualities. It is inexpensive, relatively easy to work with, and has a very long useful
life. We recommend Poly pipe for the constant-pressure mainline part of your system (the part going from your
water source to your sprinkler valves). However, we recommend our environmentally friendly Blu-Lock for all
lateral sprinkler lines (the pipes coming out of your valves that go to your sprinklers). In a typical system
lateral lines are over 80% of the total pipe used, so your system will be very "green".
WORKING WITH POLY PIPE
Use poly insert fittings and
double clamps for each connection on the mainline
