Water Supply & DistributionQuestion 32 of 360
For vertical copper water tube, how must risers be supported according to the support requirements?
a.No vertical support is ever required
b.Only at the top of the building
c.Every 40 feet regardless of stories
d.At each story or at intervals not exceeding about 10 feet
Explanation
Vertical copper piping must be supported at each story or at intervals not exceeding roughly 10 feet so the weight is not carried entirely by lower connections. Claiming no support, top-only support, or a flat 40-foot interval regardless of stories does not meet the support requirements.
