Can Schedule 40 PVC be used for drinking water?
The problem with PVC pipe is that it may have issues with leaks. It will degrade when exposed to UV light (such as sunlight), and also high temperature. Its pressure rating is to be derated at high temperatures. Because of this, PVC is not approved for use in houses for potable water.
Which PVC pipe is safe for drinking water?

Water Pressure for Sch 40 vs Sch 80. Both schedule 40 and 80 PVC are used widely around the world. Each one has its benefits in different applications. Schedule 40 pipe has thinner walls, so it is best for applications involving relatively low water pressure.
