Do you have a PVC irrigation system in your yard?
If you do, is any of it exposed to the sun? if so, it’s bad.
Because it becomes brittle by the UV Rays.
Here are the affects on PVC when exposed to sunlight over time:
|Impact Strength||Impact Resistance||Decrease|
|Tensile Strength||Pressure Capacity||No Effect|
|Modulus of Elasticity||Pipe Stiffness||No Effect|
What can be done to prevent PVC damage from the sun:
Wrap it or paint it. (wrapping is better if you live in cold climates to avoid pipes bursting due to freezing)
If you are dealing with a new installation, then use Schedule 80 PVC for anything above grade. (it’s grey) It is thicker, and is far more resistant to sunlight.
