pvc pipe is rated schedule 34, schedule 40, schedule 80 and so on. the #
dictates the wall thickness. the higher the # the thicker the wall. schedule
34 is what we call thin wall pvc. this is used primarily in sprinkler
systems and sewer lines from the house to the street. thin wall cannot be
used under a home per code. pvc cannot be used as water piping inside of a
building per code.   there are a couple of kinds of pvc on the market.
schedule 40 pvc is pressure rated. it is used for water lines and drainage.
the drainage is more under homes than sewer lines out side of the home. foam
core or cellular core is used for drainage under the home also. foam core
has a thin layer of pvc on the out side, foam on the inside then another
thin layer of pvc on the inside. foam core has the same wall thickness as
shedule 40 so it is rated as schedule 40 .  foam core cannot be used for
pressure. you ned schedule 40 or higher for tesla coil use *** enough
plumbing lets get back to coiling***
