Section 13VAC5-63-549 of Virginia's Maintenance Code regulations updates the referenced technical standards listed in Chapter 8 of the International Property Maintenance Code (IPMC) as adopted in Virginia. Specifically, it substitutes a set of ASSE 5010-series field-test procedures and a Canadian Standards Association backflow-prevention manual for whatever standards previously appeared in that chapter. These referenced standards govern the technical methods used to test and verify backflow-prevention assemblies in plumbing systems at maintained properties.
Plain English — not legal advice.
Under 13VAC5-63-549, Virginia-regulated properties must comply with the specific ASSE 5010-series field-test procedures and the CAN/CSA-B64.10-01 standard when backflow-prevention devices are tested or inspected, rather than any superseded standards. Compliant operators generally ensure that any contractor or inspector performing backflow-prevention field tests on their properties uses the procedures enumerated in this section. Keeping documentation that the correct 1991 ASSE procedures and the CSA backflow manual were followed can support a showing of compliance during a code inspection.

Section 13VAC5-63-549 establishes the technical standards that govern how backflow-prevention assemblies in a rental property's plumbing must be tested and verified under Virginia's property maintenance regulations. If a tenant has concerns about whether plumbing safety equipment at their residence has been properly tested, they may raise the applicable standards under this provision when communicating with their landlord or local code-enforcement authority. Tenant-rights organizations and local building or housing code offices can provide information about how these technical requirements connect to habitability obligations.
