Cold temperature and exposure to the sun have cracked and warped plastic piping used for rooftop sprinklers and caused some users to remove the systems they hoped would reduce cooling costs. Manufacturers of the polyvinyl chloride (PVC) pipe, however, claim the cracking was due to improper draining. Copper tubing can be used, but at a 20 to 50% increase in cost. Chemical treatment to repel ultraviolet rays must be used on PVC piping to withstand sunlight. Several users report their experiences with rooftop sprinkling systems. (DCK)
