Rehabilitation Guidelines 1980. 7. Plumbing DWV Guideline for Residential Rehabilitation
This seventh volume of an eight-volume series provides rehabilitation guidelines for use by code officials, inspectors, designers, and builders who inspect and test existing drain, waste, and vent (DWV) systems. Applicable to all types of residential occupancies, the guide's use should facilitate rehabilitation in circumstances where code requirements for new construction are being applied to a project undergoing rehabilitation. The volume reviews basic drainage and hydraulic concepts including the function of the drainage system, hydraulic principles, flow in drains and stacks, and modes of trap failure. It gives suggestions for carrying out functional performance tests for several modes of failures: self-siphonage, induced siphonage, blowback, and crossflow. The guideline also discusses inspection procedures, documentation, testing, and methods for estimating system capacity, all of which may be required to determine existing conditions. Problems and solutions are presented for correcting existing drainage, waste, and venting (DWV) system structural, hydraulic, and functional defects, and surcharged sewers; relocating fixtures; adding new fixtures to existing DWV systems, extending DWV systems, and installing new DWV systems in existing buildings; and through-the-wall venting. Diagrams are given. Two appendices list performance criteria and examples of acceptable DWV practices for building rehabilitation.
