Poly Pipe
Poly pipe, or polyethelene pipe is a flexible, usually black pipe that is used for underground spinkler line. It’s more popular in the northern areas of the country due to the cold climate.
The poly pipe is more flexible and allows for movement when the ground freezes in the winter months. Regular PVC pipe, even when the system has been blown out, would crack and end up with a lot of leaks in the spring.
Poly pipe is allows also allows for installation without trenching using a pipe puller instead of having to dig trenches in your yard.
Most commonly I use a one inch diameter line with 125 psi, but I might use a slightly smaller line depending on the amount of water flow needed and the pressure available.
