DIY Irrigation :: Poly Pipes
Poly pipes or irrigation pipe is made of black polyethylene.
The wall of this pipe is thin to allow for easy joining and fitting of drippers
and sprayers. As a general rule, 13mm pipe can be used for drippers, but 19mm
will feed more emitters. Sprayers need 19mm pipe, and pop-ups usually require
19mm or 25mm depending on water pressure.
