Abstract
A system and method for restoring water supply pipes in buildings is provided. Compressed air is blown through one end of a cold water supply pipe, such as a cold water riser, and elsewhere on the pipe the cold water supply pipe is connected to the hot water supply pipe by an air hose. Compressed air may alternatively be blown through one end of the hot water supply pipe. To clean the pipe, abrasive particles are introduced into the stream of compressed air upstream of the section of pipe to be cleaned. To line the pipe, an epoxy coating is introduced into the stream of compressed gas upstream of the section of pipe to be lined.
