We are repiping our dry cleaning plant, and I am tempted to use PVC for the vacum system. In this application, the vacum is connected to a manifold to which the dry cleaning presses are tapped. The vacum's purpose is to apply suction pressure to the bed of the press, which helps in holding the garment. The vacum also assists in "pulling" the steam through the garment and evacuating the steam out of the plant. The quantity of steam is fairly minimal, and it is not under any pressure.
What kind of PVC should I use? I have looked at schedule 80, but the water temperature rating is only around 73 degrees F. Has anyone eber encountered this?
