Can I install a PRV myself or do I need a permit?
Most jurisdictions treat PRV installation as permit-and-inspection plumbing work because it modifies the incoming service line. Many areas allow homeowner work on owner-occupied homes, but requirements vary by AHJ. Confirm local permit rules before installation and include downstream thermal expansion control where required.
