3. Building Code & Permit Fast-Brief: IRC P2801.6 & IPC 607.3 - Water Heater Expansion Tanks & Pans Permit Standards
Water Heater Thermal Expansion & Leak Containment Pans
Where a water supply has a backflow preventer, check valve, or pressure-reducing valve installed, a closed system is created. An approved device for controlling thermal expansion (such as a diaphragm thermal expansion tank pre-pressurized to match incoming municipal water pressure) is mandatory. Safety pans with dedicated 3/4" drain pipes are required when installed in locations where leaks could cause structural damage.
Is a Municipal Building Permit Required?
Yes. Plumbing replacement permits ensure proper combustion gas venting, relief valve piping, and expansion control.
Municipal Inspector Rough/Final Checklist
- ✓ Thermal expansion tank air bladder charge matched to static household water PSI.
- ✓ Temperature and pressure relief (T&P) valve discharge line pitched downward without threads on terminal end.
- ✓ Electrical bonding jumper connecting hot, cold, and gas piping.
