Includes labor, PRV valve ($40–150 part), pressure test, and adjustment to FL-standard 55–65 PSI.
Normal residential water pressure in FL is 40–80 PSI. PRVs are set to 55–65 PSI per FL Plumbing Code (FPC 604.8). Utility pressure in urban FL often runs 80–125 PSI — a working PRV is essential.
A failing PRV in a closed FL water system requires a thermal expansion tank ($100–300 installed). FL code requires expansion tanks on all water heaters in closed systems. Ask your plumber to check both.
High water pressure (over 80 PSI) voids most FL water heater and appliance warranties. If your PRV has failed, every appliance on your system is running at risk. FL insurance adjusters note failed PRVs when evaluating water damage claims.
A non-functioning PRV on a supply over 80 PSI is a code violation that must be disclosed in FL real estate transactions (FS 689.261). Replace before listing to avoid renegotiation or deal fall-through.
PRV installation or replacement requires a FL plumbing permit in most jurisdictions when it's part of a larger plumbing repair. Your CFC-licensed plumber handles the permit. Ask upfront.
