systems. 21 603.3 / P2602.3 Tracer Wire on Nonmetallic Supply Piping New VA amendment Change Summary: This requirement already exists in the 2012 VA Plumbing Code for Sanitary Drainage (703.6) and is now also a requirement for water supply piping. The requirements are identical to the

drainage tracer wire requirements. 22 605 Groove and Shouldered Mechanical Joints and Press Connect Fittings 605.14.5 Press-Connect Joints. Summary: A new standard for press-connect joints has been added.

International Code Council 37 1106.2 Vertical Conductors and Leaders (Storm Drainage) Change Type: State amendment Change Summary: This state amendment keeps the same language as in the 2012 VPC, which specifies that vertical connectors and leader sizing will continue to be based on the maximum projected roof area (and not flow rates of the piping as the 2015 IPC now

specifies) 38 Chapter 13 Nonpotable Water Systems Change Type: New chapter in the ICC code ONLY Even though the IPC now has a chapter 13 with the same name as the VA version, there are numerous significant state amendments to the 2015 VA version Always refer to the Virginia version of chapter 13 for Nonpotable Water Systems

39 Chapter 14 Subsurface Landscape Irrigation System Change Type: Completely new chapter 1401.1 Scope.
