Leak cause – magnifying glass effect

Placement of drip laterals under transparent plastic mulch can create a magnifying glass effect, where sunlight shines through droplets and concentrates beams of light that burn the tube.

Prevention methods

  • Use black plastic mulch instead.

  • If using transparent plastic mulch, lightly bury the tube under soil.

 

Remember that the magnifying glass effect can also occur during storage of the drip rolls, in particular for drip rolls that do not have cardboard packaging and are wrapped in a clear wrap. Do not leave these rolls/coils in direct sunlight before installation.
