Can PVC be exposed to the sun?
PVC does surprisingly well when exposed to ultra violet rays (sunlight). Research shows little to no effect on PVC’s tensile strength or elasticity after prolonged sun exposure. The only degradation that seems to occur is impact strength.
Can Schedule 40 be exposed to sunlight?
As far as the impact of environmental factors is concerned, both Schedule 40 and Schedule 80 PVC pipes hold up well to soil corrosiveness, rain, etc. However, prolonged exposure to sunlight may affect the structural integrity of PVC pipes.

What’s the difference between Schedule 40 PVC and regular PVC?
Schedule 40 PVC is usually white in color and has thinner walls, thus can handle less pressure than it’s counterpart. Schedule 40 PVC pipe works best for low water pressure applications. By contrast, Schedule 80 PVC is usually gray in color and has thicker walls; therefore, it can handle higher water pressures.

What is the difference between Schedule 40 and SDR 35?
SDR will bend with the shifting and settling. Having a higher flex tolerance means less breaks from the soil conditions. Schedule 40 is so rigid that in the event the ground shifts or settles this pipe has no give. It will simply snap or break from the pressure.
Can you mix GREY and white PVC?
