Model TP-102, this valve features a 2-inch shank and fits all applicable AO SMITH residential water heater configurations, including direct vent models. The TP relief valve is a critical safety device that automatically opens to release excess pressure or dangerously high temperatures inside the water heater tank, preventing catastrophic failure.

This valve is suited for residential water heater installations where a TP relief valve replacement is required. Its 2-inch shank accommodates standard discharge port fittings found on residential tank-style water heaters. The TP-102 designation covers a broad range of AO SMITH residential models, including direct vent configurations, making it a practical stock item for plumbing service technicians who regularly service AO SMITH equipment.

Installation Notes

TP relief valve replacement is a plumbing task that should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Before servicing, shut off the cold water supply and power or gas to the water heater and allow the tank to cool.
