This section shall govern the replacement of existing building sewer piping by PVC Fold and Form methods.

The replacement of building sewer piping by PVC fold and form methods shall be limited to gravity drainage piping 4 inches (102 mm) to 18 inches (457 mm). The replacement piping shall be of the same nominal size as the existing piping.

The existing piping sections to be replaced shall be inspected internally by a recorded video camera survey. The survey shall include notations of the position of cleanouts and the depth of connections to the existing piping.

The replacement piping shall be manufactured in compliance with ASTM F1504 or ASTM F1871.

The piping sections to be replaced shall be cleaned and flushed. Remediation shall be performed where there is groundwater infiltration, roots, collapsed pipe, dropped joints, offsets more than 12 percent of the inside pipe diameter or other obstructions.

Where the existing building sewer did not have cleanouts meeting the requirements of this code, cleanout fittings shall be installed as required by this code.

The completed replacement piping shall be inspected internally by a recorded video camera survey. The video survey shall be reviewed and approved by the building official prior to pressure testing of the replacement piping system.

The replacement piping system as well as the connections to the replacement piping shall be tested in accordance with Section P2503.4.
